Understanding the cause of an inadequate soybean stand is important to help prevent a reoccurrence of the problem if the decision is made to replant. Final soybean plant stands of at least 73,000 plants per acre provide 90 percent or more of maximum yield potential. Make weed control a high priority in fields with reduced stands.
Soybean yield potential is the result of many factors: genetics, environmental conditions and management practices. Additionally, deficient nutrient levels in the soil can also affect yield. When nutrients are limited, photosynthesis, water transport, and protein, oil and carbohydrate production can be negatively affected. A simple soil test can help evaluate the deficiencies and increase yields.

Nitrogen is an integral nutrient when it comes to plant health. Crops find it both in the soil and through fertilizers applied in early spring. Unfortunately, nitrogen is susceptible to loss via ammonia volatilization, nitrate leeching and denitrification. Rainfall, soil types and fertilizer application play a roll in how much of your nitrogen investment gets…
Soil analysis is a great tool to assess what soil amendments are needed for optimum plant function and yield potential. Soil test results list the soil test concentration for specific parameters along with an interpretation value (low, optimum, and high) and a recommendation This Spotlight will help explain the meaning of each soil test parameter,…
Nutrients are required for water transport and photosynthesis processes, and protein and oil production in the plant. Nutrient deficiencies are one of the causes of leaf discoloration and/or chlorosis that might be observed in a soybean field and can decrease plant growth and reduce yield potential. It is beneficial to understand the function of a…
Higher corn yields mean more minor nutrients are removed from the soil; thus, minor nutrient deficiencies may occur. Starter fertilizer is one way to help ensure nutrient availability to the crop early in the season. While sulfur (S) and zinc (Zn) are needed in smaller quantities than nitrogen (N), phosphorus (P), and potassium (K), it…
Several fields are showing what is believed to be nutrient deficiency. Several causes including weather, soil conditions, and nutrient availability may contribute to this symptom. Questions regarding whether the deficiency is due to processes within the plant, problems with root uptake, or an actual soil deficiency should be answered before making additional fertilizer applications this…
Achieving maximum soybean yield potential will likely depend on increases in stress tolerance, efficient use of all plant growth resources, and increased biomass production. A variety of agronomic practices have shown benefit to increasing soybean yield potential. Selecting what works best on your farm requires careful consideration and implementation. Agronomic Spotlight – Maximizing Soybean Yield…
Whether it is with site specific grid sampling, or more traditional methods, soil testing is the most useful means of determining what inventories of nutrients are available for crop production. In a period of rising fertilizer prices, soil testing allows a grower to prioritize fertilizer applications, and focus on inputs that will provide the greatest…
