Key Considerations for Soybean Crops

NUTRIENT MANAGEMENT

Soybeans are commonly used as a rotation crop to improve soil health, since they produce most of their own nitrogen through rhizobium. Inoculants can help generate nitrogen, the most required nutrient for sufficient crop growth and yield.

SOIL AND TEMPERATURE REQUIREMENTS

The ideal soil type for soybean growth is typically well-drained, loamy soils. Soybean roots are very sensitive to acids and they like the heat. They utilize moisture very efficiently and are tolerant to moderate drought stress.

PEST MANAGEMENT

Fortunately, soybeans are fairly tolerant to insect and pest damage, but insecticides can be applied if insect populations are particularly high. If your soybeans are experiencing disease pressure, applying fungicides along with an integrated pest management plan is key.

Key Nutrients

• Nitrogen — For the most part, nitrogen is self-regulated in soybean crops. However, it should still be incorporated into your nutrient management plan.
• Phosphorus — Proper phosphorus levels are essential for plant development and can help ensure N fixation.
• Potassium — Soybeans require fairly high amounts of potassium, since it influences water efficiency, the number of seeds per plant and helps with disease prevention.
• Micronutrients — While soybeans are usually good at absorbing the micronutrients they need from the soil, sulfur has a tendency to fall by the wayside. Consider sulfur applications to ensure your crops are getting all the nutrients they need.
