Introduction

This manual covers the following tasks for 60-foot three-section Yield-Pro®Planters equipped with Air-Pro seed meters:

• setting and checking seed rate for singulated crops

• applying liquid fertilizer from optional tanks on-board

the planter, or from a trailing cart.

This manual is your guide to planter adjustments for achieving speciﬁc seed population targets. It also includes information you may need to properly setup and adjust a separately provisioned fertilizer tank and pump system.

Although some setup/adjustment material herein is repeated from the Operator’s Manual, you need to be thoroughly familiar with planter operations and adjustments before applying this Seed Rate manual and its table data.

Rate Setting Overview

Setting Planting Rate

There are ﬁve or six steps to obtaining the desired number of seeds per acre, depending on row conﬁguration. This data applies to the Air-Pro when planting at one

1. For your crop, determine your intended population, in seeds/acre or seeds/hectare. If you know only the seed spacing or pounds/acre (kg/hectare), consult the charts on page 2 through page 4.

2. For your crop, population and desired ﬁeld speed, verify the suitability and setup of your seed disk: See “Air-Pro® Meter Disk Selection” on page 5.

3. Set initial seed inlet shutter per seed rate chart. Set initial meter pressurization per page 8, 9.

4. Sprocket index for staggered twin-row Twin-row planters, with certain crops, get maximum beneﬁt with precise seed spacing between adjacent rows. See “Indexing Fine Adjustment” on page 25.

5. Set meter rate This is done via the seed monitor. Once data about your planter is entered, you select the seed rate directly. Consult the manual for the seed monitor.

6. Check planting rate See “Checking Planting Rate” on page 10.

meter

Setting Fertilizer Rate

If your planter is equipped with one or both optional fertilizer manifold systems, it does not include the tank.

If the planter has a Type 2b (formerly referred to as a “starter”) manifold, it may rely on an off-planter pump, or may use one or two ground drive pumps on the planter.

See “Ground Drive Fertilizer Rate” on page 42 for ground drive pump conﬁguration.

If the planter has a Type 3 “hi rate”) manifold, it relies on an off-planter pump, typically the pump on a Great Plains PFC1600 or PFC2000 tank cart.

Rate setting for the cart pump is found in the cart’s Operator manual.

Rate is controlled by the pump. Consistent distribution requires using the correct size oriﬁces in the manifolds. If the oriﬁce size is too large, ﬂow may not be even across all rows. If the oriﬁce size is too small, material may be dumped at the relief valve.

See “Fertilizer Rate” on page 39 for oriﬁce information.

b. Type 2 and Type 3 are described in the YP2425A

Operator manual, under Setup topic “Fertilizer Connections”.

Population Reference Information

Seeds Per Unit

If only pounds/acre (kilograms/hectare) is known, obtain the population count by multiplying the weight by the “Kernels per pound” value from the seed container.

Example: Milo

Target rate: 4.5 pounds/acre Seed density: 14500 seeds/pound Population: = Rate × Density

= 4.5 × 14500, or: 65250 seeds/acre

Seed Spacing

If only seed spacing is known, use the tables on the next ﬁve pages to determine population.

Checking Planting Rate

Singulated seed charts are based on cleaned and sized seed singulated with the recommended disk. Extreme seed size variations and foreign material can affect the planting rate.

Any material difference between chart and ﬁeld rates implies a mechanical malfunction, a planter setup error or extremely worn planter components. You can verify your setup and planter performance by measuring seed placement and spacing over a relatively short distance.

The columns to the right provide example data for a rate check, in U.S. customary units and a similar example metric units.

Checking Singulated Rates

1. Determine the sample distance to check. Find your row spacing in the table at right.

2. Note the number of rows to sample. Adjust the planting depth to a shallow setting on one or two outside rows (per table). Tie up the press wheel arms with wire or bungee to prevent furrow closure.

3. For populations above 100 000 seeds/acre, use a sample size of 1/1000th acre.

For populations below 100 000 seeds/acre, use a sample size of 1/200th acre.

4. Conﬁgure the planter for the chart rate, either using the chart settings for sprockets, or, with hydraulic drive, selecting the rate on the seed monitor.

5. Plant at the desired planting speed for slightly more than the computed sample run length.

6. Measure off the sample distance, balanced in between where seeding started and stopped.

7. Count the number of seeds over the distance measured. Also note the consistency of the seed spacing.

8. Compute the rate for a full acre or hectare.

For a 1/1000th sample, multiply the counted seeds by 1000.

For a 1/200th sample, multiply the counted seeds by

200.

9. If the ﬁeld and chart rates vary by more than a few percent, re-check planter setup, including meter disk or cell count, air system, hydraulic drive setup, chain slack, etc. If seed spacing is irregular, this suggests a seed delivery problem, and not a rate setup problem.

10. While planting, pay attention to the seed monitor. In addition to conﬁrming the single-row furrow check, it will also provide ﬁeld rate data on all the other rows, and alert you to any irregularities or stoppages.

Planting Rate

Singulated planting employs the seed monitor in “PLANTER CONTROL” mode.

Hydraulic Drive Meter Rate

Hydraulic drive meter rate is set directly on the seed monitor in the tractor. Consult the monitor manual for detailed instructions, which may vary slightly over time with ﬁrmware updates to the monitor system.

Enter/update your planter conﬁguration (width/row-count, single-row/twin, disk cell count, etc.). Once entered, specify the population directly in seeds/acre or seeds/ha.

Enter meter RPM limits for your disk (pages 13-20).

Note: For consistent results, and least meter wear, do not

exceed the recommended ground speed.

For step 1 through step 4, any needed data not provided in this manual can be found in one or more of:

DICKEY-john

Quick Start Guide

Planter Operator Manual Refer to the DICKEY-john®IntelliAg® Planter/Drill Control Operator’s Manual for details on setup item.

Note: The monitor must be in User Level 2 to change

some of these parameters.

1. For a crop not previously planted with this planter,

create a “Material Name” for the crop. Selecting a named material is a required step in later screens.

2. Verify, and as needed setup or update the “Material”

record for the singulated seed to be planted.

The table at right lists the parameters that need to be reviewed or set. <angle bracket> values are your choice/preference when not from meter rpm chart.

3. Verify, and as necessary setup or update the

“Channel” assigned to the planter’s hydraulic drive. If the monitor resets to defaults, Gear Ratio may be incorrect.

Count rows individually for “# Seed Rows”. A twin pair (if both openers are in use) counts as 2 rows. “Channel Width” is swath.

4. In the Material Library screen, makes sure that the

Material (SOYBEANS in our example) is assigned to the Channel (CH 1 in our example) which controls the planter’s hydraulic drive.

5. Perform a Valve Calibration for the control channel.

6. Switch the seed monitor from Setup/Conﬁguration

mode to Operate mode. Load seed. Move the planter to the ﬁeld.

If you are planting:

• with a seed disc having 24 cells or less,

• twin-row crops,

• at seed populations below 45,000 seeds/ac (111 000 seeds/ha),

you can synchronize each pair of adjacent meters in a twin row so that you achieve the maximum seed-to-seed spacing between the units of the pair.

If the initial indexing does not provide equal spacing, see “Indexing Fine Adjustment” on page 25.

If you are planting:

- single-row,

- or with seed discs or 25 cells or more,

- or a volumetric crop,

- or twin row with seed spacings below

91⁄4inch (23.5 cm), this section of the manual, and the sprocket indexing charts, do not apply to your operations.

Indexing Preparation

Tools required:

•7⁄8inch (23 mm) open end wrench

•3⁄8inch socket wrench, or any socket wrench with3⁄8in. (9.5 mm) square drive

• 812-391C timing tool (located under walkboard)

1. Find (in page 26-27) the sprocket indexing chart for your row spacing, cell count and desired seed population. Note the “Initial Rear Tooth Number” value in the second column.

2. Raise the planter. Chain geometry changes slightly when lowered. The indexing charts account for this change, and assume the planter is raised. Also, raising the planter disengages the drive clutches, allowing you to turn the drive shaft with a hand tool.

3. Clean out meters. Leave seed discs out. See Operator Manual for procedure.

Note: The 812-391C tool was introduced in late 2010.

Check latest Parts manual for storage mount hardware part numbers.

Note: Sprocket indexing is possible with seed present

and discs installed, but if so, you must perform step 9 (chain taut check) by rotating the drive shaft forward to remove slack. Reverse meter rotation, with seed present, is not recommended.

812-391C Timing Tool

Figure 5

31445

Basic Indexing

Refer to Figure 6 (which depicts tooth 1 slightly ahead of the index rib at 2:00)

4. Use drive shaft to set front row unit to index 1.

Observe the meter drive sprocket at a front (short mount) row unit on each wing. Use the wrench, from the rear of the shaft, to rotate the shaft forward (wrench up and forward).

Stop rotation when the tip of the tooth stamped “1” is aligned with a rib cast into the meter housing. In general, the 2:00 rib is the easiest to use, as it is visible from the side and from behind the meter.

5. Check front sprocket synchronization.

Inspect all meter drive sprockets on front row units. Check that all springs are taut, and no chains have slack. All sprockets should be at “1”. If not, use step 6 through step 10 to set them to 1. Although front sprockets machine-wide may be at 1 after this check, sprockets do not remain in sync wing-to-wing, due to clutch operation.

With Swath Command™, front sprockets are not synchronized planter-wide. With row clutches, each front sprocket must be checked when timing the mating rear sprocket of the row pair. The front row can be advanced by manually turning the tandem sprocket forward until the front sprocket is at 1. Then set the rear sprocket. Check that the front sprocket has not moved.

Figure 6

Sprocket Indexing Reference

Equipment Damage Risk:

Do not apply signiﬁcant force to meter disk, or drive hub may be damaged.

Note: Without Swath Command™: In the future, ﬁnding

front sprockets out of sync on a wing suggests idler spring problems, and/or worn chain. Row drive systems must be in reliable working order for effective sprocket indexing.

6. At the rear (long mount) row unit of each pair, note which sprocket tooth is at the index mark . If the

sprocket is already at the chart value, skip to step 12. Otherwise, complete step 7 through step 10 for that row.

Refer to Figure 8

7. Place the timing tool over the meter shaft. Attach

a3⁄8inch (10 mm) socket wrench to aid in rotation.

Sweep the toolatooth under the chain, rotating in the direction opposite of that desired for sprocket adjustment.

Each clockwise rotation of the timing tool advances the sprocket by one tooth.

Figure 7

29628

Sprocket Index Check Each counter-clockwise rotation of the timing tool retards the sprocket by one tooth.

8. Advance or retard the sprocket until the desired tooth number is at the index mark. Hold the sprocket stationary, and re-mount the chain, making sure the chain is taut in the top loop.

9. Rotate meter shaft backward, or rotate wing drive shaft forward to tension chain. Re-check that front

row sprocket is still at “1”.

10. Check the position of the rear row sprocket. The tooth tip at, or just ahead of the index mark must be the tooth called for by the chart. If not, release spring and re-mount chain.

11. Repeat step 4 through step 10 for each row pair.

12. Re-install seed discs and meter covers. No particular disc orientation is required during seed disc installation. The disc is symmetrical about all four seat lobes.

Indexing Fine Adjustment

If, after indexing, the twin-row side-to-side seed stagger is substantially imbalanced, it is possible to make small adjustments that may correct it. Imbalance can occur over time as row unit chains wear and stretch.

The Indexing charts on page 26 and 27 provide columns for alternate rear row sprocket alignments. These settings move the placement of the rear seed drop. The amount of movement is given as a percentage (±20% or ±40%) of the in-row seed spacing.

Refer to Figure 9

Adjustments are made only to the rear row timing.

• Advancing the timing (dropping the seed sooner, moves the seed position back).

• Retarding the timing moves the seed position forward.

40% Rear Timing Adjustments

Figure 9

If an adjustment is made, test it on one row pair before adjusting the entire planter.

Indexing Adjustment Steps

1. Make sure the current front sprocket index is 1, and

the current rear sprocket index number matches the “Initial” number in the indexing chart for the population being planted.

2. Measure the actual stagger at the rear row seeds.

3. Determine by how many inches (or cm) the rear

seed placement needs to move in order to be centered between the front seed placements.

4. Determine the percent of seed spacing, and whether

advance or retard, required to adjust the rear seed drop to the desired spot.

5. In the tables (thumbnail view of one shown at right),

ﬁnd the new rear sprocket tooth setting for the percent retard or advance desired.

Example:

The front sprocket is “1”. At a target population of 31,500 seeds/ac, the rear sprocket is at tooth “17”.

At this population, spacing in a single row is:

13.3 inches

The rear row seeds would be ideally at:

6.6 inches

ahead or behind the front row seeds.

We ﬁnd that the rear seeds are being placed:

1.5 inches behind the front seeds.

We need to move the rear seeds back another 5.1 in.

A 40% advance is 5.3 inches at this seed spacing.

General Information

Refer to Figure 10

These instructions explain how to operate and calibrate the Air-Pro® No. 1 84 cell volumetric seed disc .

Clean-Out Meters

Possible Chemical Hazard:

Avoid contact with seed treatment residues inside meters and on removed meter discs. Wear gloves unless all recent planting involved untreated seeds. Consult the MSDSa for any treated seeds recently planted. See planter Operator manual for brush cleaning instructions.

1. Perform a meter clean-out per the instructions in your planter Operator manual.

2. Remove and store the current seed discs. Perform a brush inspection and cleaning as necessary.

3. Continue at “Install Discs / Set Shutters” on page 29.

Grain Shield

To order the grain shield use the following Great Plains part number: 403-596A VOLUMETRIC METER GRAIN SHIELD

When planting with the volumetric disk, a very small percentage of grain may be lost out the opening at the back of the seed tube. If the amount of loss is more than you desire the grain shield can be installed to stop this.

Note: It is highly recommended that the grain shield be

removed from the meter when going back to larger singulated seed.

Refer to Figure 12

To install:

4. Remove the strip and block brush assembly. Save the washer for reuse in step 6.

5. Remove the

⁄16inch hex-headed bolt and discard, it

is replaced with the5⁄16inch button head cap screw.

6. Position the grain shield and reinstall with the

Take Note of Meter Pressure

Due to delivery of multiple seeds per disc cell, a volumetric crop requires a speciﬁc value of disc pressurization.

Initial Meter Pressurization: Wheat

2.0 inches of water Hard Red Winter (HRW)

2.5 inches of water Soft Red Winter (SRW)

Note: Do not operate below 2.0 inches of water

10. Note the suggested initial meter pressure. Have this value at hand in the tractor cab.

Calibrate

Calibration is essential for accurate populations:

• Seed monitors cannot accurately count individual

seeds in volumetric planting, both due to the small seed size, and due to multiple seeds per cell being often detected as one seed.

• Ground drive charts are only approximate, and only for

the seed variety and conditions used to develop the chart.

• Your own rate records may also be approximate. The

same seed variety planted at a different date can require a rate adjustment due to different seed density, different weather, different ﬁeld speed, etc.

11. Calibrate your seed rate.

Population Risk:

Volumetric planting based strictly on ground drive charts is likely to be inaccurate. Volumetric planting based on seed monitor seed counts is certain to be inaccurate. Calibrate. Check your actual rate by weight or by furrow count. Check your seed consumption when reﬁlling.

For hydraulic drive planters, use the “Spreader Calibration” feature of the seed monitor.

For ground drive (or hydraulic drive) planters, rely on a “seeds per row foot” furrow check, the next topic.

Volumetric Monitor Setup

In volumetric planting, the seed monitor operates basically as a blockage detector. Any seed drop rate information is only approximate.

DICKEY-john®IntelliAg® Volumetric

In volumetric planting, the seed monitor is operated in: “GRAN SEED CONTROL” (hydraulic drive) or “GRAN SEED MONITOR” (ground drive). This is a change from the: “PLANTER CONTROL” (hydraulic drive) and “MONITOR ONLY” (ground drive) modes used for singulated crops.

IntelliAg® Hydraulic Drive

The planter needs to be hitched to the tractor in which the DICKEY-john® virtual terminal (VT) is installed.

1. Power up the seed monitor (usually via tractor ignition). Clear or resolve any alarms. The system is in User Level 1.

2. Change monitor to User Level 2. See PDC manual, or consult with dealer for procedure.

You need a light weight container for each row sampled, and a scale that is accurate at the expected sample weight. Great Plains recommends using enough rows and/or revolutions to generate a sample of about 10 pounds (4.5 kg), ideally:

• Use at least two rows.

• Use no fewer than 5 meter revolutions.

For Example 4 containers each weighing: 8 oz.

Fertilizer Rate

The YP2425A planter optionally includes one or two fertilizer manifolds, and may include one or two ground-driven pumps for the Type 2 manifold. Tank(s) and any off-planter pump(s) are usually located on a trailing tank cart.

The Great Plains PFC1600 (single tank) and PFC2000 (dual tank) tanks include a single pump. Refer to the tank Operator’s Manual for pump settings at the tank.

Note: Great Plains recommends checking with your local

Agronomist as soil conditions vary. Soil conditions in your area may need lesser or more amounts of fertilizer than represented in these charts. Do not exceed 12 gallons/ac (112 liters/Ha) in any case.

Fertilizer rate is independent of seed rate. Fertilizer rates are set by the pump systems. On-planter ground drive pump operations are described on page 42 and in the YP2425A Operator’s Manual. Off-planter pump operations are described in the tank manual.

Manifold systems include oriﬁce plates at each row unit drop line. Each fertilizer system normally includes a pressure relief valve and strainer. These components affect consistency of ﬂow across all rows.

Adjust the relief valve(s) per the YP2425A Operator’s Manual and/or tank Operator’s Manual.

Oriﬁce Plate Selection

Refer to Figure 19

Oriﬁce plates at each drop line nozzle provide back-pressure that balances ﬂow in the manifolds, assuring that each row obtains the same ﬂow rate. Plates are provided with the system(s) in three sizes. Additional sizes are available.

In general, the oriﬁce needs to be small enough to create a minimum pressure in the manifold but large enough to prevent the manifold pressure from exceeding the maximum: 15 psi min., 15-40 optimal, 65 psi max.

Using an oriﬁce size too large can result in unequal ﬂow at rows. Using a size too small can cause excess back-pressure resulting in material dumping at the relief valve.

Agricultural Chemical Hazard:

Wear protective gloves when changing oriﬁce plates. Consult material manufacturer or supplier documents for proper handling and steps to take if skin contact occurs.

Material Loss/Equipment Damage Risk:

Set application rate at pump using pump drive chart., not by oriﬁce size. Oriﬁce size is only used to create 15-65 PSI back pressure to provide even ﬂow between rows. An oriﬁce size too small causes material loss at relief valve. A size too large can cause application imbalance across the planter.

Strainer

Refer to Figure 20

A Banjo brand strainer is supplied with the ground drive fertilizer pump. It is plumbed before the Hypro pump. The standard 80 mesh screen should be suitable for most

applications. Other screen sizes are available from Banjo Corporation.

Agricultural Chemical Hazard:

Wear protective gloves when changing screens. Consult material manufacturer or supplier documents for proper handling and steps to take if skin contact occurs.

If changing screen sizes, keep in mind the following.

• A smaller mesh (100) will keep very small manifold oriﬁce plates from plugging so often. However, the screen will have to be cleaned more often.

• A larger mesh (50) or (30) will pass more material but should only be considered when using large manifold oriﬁce plates.

• A plugged or partially plugged screen will starve the pump resulting in a reduced application rate.

• Mesh sizes: (Smallest) 100, 80, 50, 30 (Largest)

Ground Drive Fertilizer Rate

One or two JohnBlue ground drive pumps customarily supply a Type 2 boom on the planter.

JohnBlue Pump Rate

Refer to Figure 21 and Figure 22

One piston pump generally sufﬁces for “starter” application rates. Two piston pumps may be required for higher rates.

Coarse rate is set by a single “driving” sprocket on the ground drive assembly. Fine rate is set on a dial (setting

hub) at the pump, using a tool supplied with the pump.

Rate settings may be established in any of three ways:

• the table on the next page,

• the slide chart provided with the pump, or;

• a calculator on the JohnBlue internet web site (www.cds-johnblue.com)

1. Check plumbing setup. See “Setting Relief Valve”

and “Strainer” in the Operator Manual.

2. Determine Driving sprocket (15T or 47T) required

from table, slide chart or web calculator. If this sprocket is already installed on driven shaft, skip to step 7. Otherwise, to change sprocket, continue with step 3.

3. Remove knob and guard . Loosen idler , and

remove chain from lower jackshaft .

4. Select the new sprocket from the storage shaft .

Remove the pins, and exchange sprockets. Store the previous sprocket on the storage shaft.

5. Remount the chain . Re-engage idler , tightening

so that the longest span of the chain has

⁄4inch (6 mm) slack.

6. Remount guard and secure with knob .

Refer to Figure 22

7. Using the box-wrench end of the JohnBlue

115681-01 tool, loosen the setting pointer nut .

8. Use the other end of the tool to rotate the dial to

the setting determined by table, slide chart or web.

9. Re-tighten pointer nut.

Setting Relief Valve

A relief valve is plumbed after the pump outlet to protect the manifold and pump from excessive pressure. Any product that dumps over the relief valve will discharge from the dump line .

To set relief valve:

Refer to Figure 24

1. Unlock plastic jam nut from relief valve knob .

2. Unscrew knob clockwise until it loses contact with

internal spring.

3. Screw knob counterclockwise two turns. Start at this

setting.

4. Observe manifold gauge . Watch for relief valve

discharge while operating in the ﬁeld.

5. If valve is dumping product and gauge reads under

65 psi, stop tractor and, looking down, turn knob clockwise1⁄4turn. Continue operating at normal ﬁeld speed. Repeat this step as needed until no product is discharged from relief valve.

6. If pressure gauge reads above 65 psi, change to a

larger oriﬁce. Go to step 2. Repeat steps.

Ezee Glide Plus Lubricant

To maximize performance of Great Plains metering systems, it is imperative to use only “Ezee Glide Plus” lubricant. “Ezee Glide Plus” Talc-Graphite lubricant is mandatory for all seeds, especially treated or inoculated seed. Thorough mixing of seed and added lubricant

is required.

Recommended Usage:

For clean seeds other than milo, cotton, and sunﬂowers sprinkle one cup of Ezee Glide Plus Talc per 4 bushels or units (170 ml per 100 liters) of seed.

For milo, cotton, and sunﬂowers double the application to one cup (or more) per 2 bu or units (335 ml per 100 liters) of seed.

Adjust this rate as necessary so all seeds become coated while avoiding an accumulation of lubricant in the bottom of the hopper.

For seed with excessive treatment, or for humid planting environments, increase the rate as needed for smooth meter operation.

29248

Irritation and Chronic Exposure Hazard:

Wear gloves. DO NOT use hands or any part of your body to mix seed lubricant. Wear a respirator when transferring and mixing. Avoid breathing lubricant dust. Not an acute hazard. May cause mechanical eye or skin irritation in high concentrations. As with all mineral spills, minimize dusting during clean-up. Prolonged inhalation may cause lung injury. Product can become slippery when wet.

Meter Pressurization - Metric

Meter pressurization in U.S. customary units begins on page 8. Refer to the Operator Manual for the procedure for ﬁne tuning meter pressurization.

Start with pressures from below and on page 9, which are based on crop, and for corn, seed shape and density.

Note: These are suggested initial (starting) pressures.

Use the seed monitor console to adjust them up or down per the procedure in the YP2425A Operator Manuals.

Corn: Reading a Pressure Chart (below, next page)

1. Pick the chart based on seed shape (ﬂat, round). Example: large round corn

2. Pick a line based on seed size (large, small). Example: the right line below

3. Find the seed density on the bottom scale. Example: 2800 seeds/kg

4. Read the suggested starting pressure on the left scale, where the line (example shown as dotted gray) intersects the density. Example: 3.4 inches of water

Initial seed inlet Shutter for corn is: 3

Initial Meter Pressurization: Cotton

1.5 inches of water (any seed density) Initial seed inlet Shutter: 2

Initial Meter Pressurization: Milo

1.5 inches of water (all disk, any seed density) Initial seed inlet Shutter: 1

Initial Meter Pressurization: Soybeans

2.0 inches of water (84 cell disk, any seed density)

3.0 inches of water (168 cell disk, any seed density) Initial seed inlet Shutter: 2

Initial Meter Pressurization: Sunﬂower

Disk: 817-851C SUNFLOWER OIL LARGE 18700 seeds/kg (or fewer):

18700 - 15400 s/kg 1.25 inches of water 15400 - 12100 s/kg 1.75 inches of water 12100 s/kg and fewer 2.25 inches of water

Volumetric Furrow Checking Rate - Metric

a. Conﬁgure the planter for the approximate rate, based

on the charts.

b. Set the meter pressure to the chart value.

c. Prime the meters. See your planter Operator manual

for the steps.

d. Plant for a short distance, just until the air delivery

system is stabilized, and the meters are all delivering seed.

e. Select one or more rows to sample.

Row Spacing Seeds per Population Kilograms per Hectare

Centimeters Row Meter Seeds/Hectare

f. Set the planting depth to shallow for the sample

row(s). Set the press wheels to minimum force. Use a wire to tie up the press wheel assembly.

g. Resume planting for a short distance.

h. Use a sampled row lengtha of one meter.

Count the seeds.

i. Find the nearest “Seeds per Row Meter” in the table

for your row spacing.

j. Look up the Population, or “Kilograms per hectare”.
