Seeding Hints
Choose your field using these guidelines
- Field should be relatively free of stones
- If stones are present, field should be harrow packed or rolled.
- Soybeans are adaptable to most soils. They can handle drought and excessive moisture.
- Chemical residue may be a concern if using repetitive applications of Assert, Lontrel, Glean and Muster.
- Avoid recently manured, fertilized or soils with very high natural fertilizer.
Determine seeding date and rate:
- Approximate seeding date range of May 1st to May 25th. As a loose guideline the latest planting date is June 6th. Planting too early is a risk as a spring freeze may destroy the seedlings.
- Minimum soil temp of 9 degrees Celsius. Planting in cool, wet soil may result in low germination, increased incidence of seedling diseases and poor stands.
- Frost tolerance to -3 degrees Celsius.
- Seeding Rate is 180-200,000 plants per acre. High planting rates may cause yields to decrease in low rainfall years due to drought stress and may lodge more & be susceptible to sclerotinia in good rainfall years. However a slightly higher planting rate can be an advantage in order to provide more height from the bottom pod set to the ground. This is especially true with RR soybeans that tend to be lower set.
- Seed depth should be between ¾” to 1 ½”
- Can be seeded with an air seeder, press drill or row crop planter (with proper plates).
RULE OF THUMB: SMALLER SEED SIZE, LOWERS YOUR INPUTS COST
| Variety | Seed Size | Lbs per Acres | Bags per Acre | Cost per Acre |
| competition | 2650 | 75.47 | 1.51 | $ 60.38 |
| competition | 2900 | 68.97 | 1.38 | $55.17 |
| 23005RR | 3350 | 59.70 | 1.19 | $47.76 |
| Our New variety 2006 | 4300 | 46.51 | 0.93 | $37.21 |
Calculation breakdown: 200,000 plants per acre / Seed Size = lbs per acre L per acre / 50 lb bags = Bags per acre.
Price per bag x Bags per acre = Cost per acre *we used 200,000 plants per acre in this example & cost of $40 per bag.
Monsanto Tech Fee
All Roundup Ready® soybeans have the tech fee included in the price of the seed. There is no additional fee per acre on top of that. You must sign a Tech Agreement & provide your Monsanto Tech # (same # that is used for RR® canola)
