➢ Soil Adaptation: Adapted to most soil types and conditions. Soil drainage is important as standing water on soybean plants for extended periods is not beneficial.
➢ Planting Dates: April 15 through July. Earlier planting dates generally allows for more forage production. Planting during “Green Up” of the area’s native plants make take some browse pressure off of the soybeans allowing them attain some growth.
➢ Soil pH Range: 5.5 to 7.0
➢ Fertilization: Apply fertilizer according to soil test recommendations. May apply 50 lbs/ac of 0-46-0 and 50 lbs/ac of 0-0-60 at time of planting.
➢ Soil Preparation: Plant in a well-prepared, firm seedbed. Planting “No-Till” works well if the proper equipment is available, and if the right herbicides are used properly to reduce weeds at planting.
➢ Planting Rates: If using a seed drill or planter, plant at least 140,000 seeds per acre. Most bags of soybeans contain at least 140,000 seed. If planting for cattle forage, plant at a rate greater than 140,000 seed per acre to get smaller diameter plant stems.
If broadcasting, plant 1.5 bags per acre into a well prepared seedbed. Cover seeds to 1 inch deep.
➢ Inoculant Strain: S Inoculant is needed the first year soybeans are planted on ground where soybeans have never planted or have not been planted in a long time. It is strongly encouraged to use inoculant each year soybeans are planted. Research has shown a yield increase for soybeans that are inoculated each year as compared to soybeans that are not. Inoculant is cheap insurance.
➢ Management: Large plots may be required in areas of high deer density and you may have to prevent grazing for the first month following germination to allow plots to become established.
➢ Recommended Herbicides: Use a preemergence application of Pursuit (4 fl. oz/ac) or Prowl 3.3 EC (1 to 3 pts/ac) to control many warm-season annual weeds. Use a postemergence application of Select (10 fl. oz/ac) or Poast Plus (2 to 3 pts/ac) to control grass weeds. Where sicklepod is a problem, we recommend a postemergence application of either Frontrow (0.4 fl. oz/ac), Blazer (2 pts/ac), or Butyrac 200 (2 pts/ac). You can also use an early postemergence application of Pursuit to control grass weeds. Many commercial herbicides available for soybeans include glyphosate-tolerant technology.
