 CORN

 

Corn requires large quantities of nitrogen per bushel of grain produced. Nitrogen recommendations will vary according to potential yield goal, soil type, organic matter content in the soil and the previous crop. Corn removes approximately 1.2 pounds of nitrogen, .35 pounds of phosphorus and .25 pounds of potassium per bushel of grain. It is important to supply the corn crop with the appropriate amount of nitrogen, phosphorus and potassium to obtain potential yield goals.

    To maximize corn yields, make sure a soil test indicates that your soil has an optimum level of phosphorus and potassium. Then apply the recommended amounts of nitrogen, phosphorus and potassium based on grain removal. The calculator below will help you determine the recommended amount of nitrogen, phosphorus and potassium needed based on grain removal only.

 SOYBEANS

  

Soybeans require large quantities of nitrogen, phosphorous and potassium. Most of the nitrogen needed is obtained from the atmosphere. Phosphorous and potassium recommendations will vary according to potential yield goal and the soil?s ability to supply nutrients to the crop. Soybeans remove approximately .90 pounds of phosphorous and 1.50 pounds of potassium per bushel of grain. It is important to supply the soybean crop with the appropriate amount of phosphorous and potassium to achieve the potential yield goals.

To maximize soybean yields, your soil test should indicate that your soil is at optimum level for pH, phosphorous and potassium. Then apply the recommended amount of phosphorous and potassium based on grain removal for yield goal.

The calculator below will assist you to determine the recommended amount of phosphorous and potassium needed based on grain removal only.

Wheat fertility 
 Wheat can require large quantities of nitrogen, phosphorus and potassium. Nitrogen recommendations will vary according to potential yield goal, soil type, organic matter content in the soil and the previous crop. Wheat can remove approximately 1.3 pounds of nitrogen, .60 pounds of phosphorus and .40 pounds of potassium, .10 pounds of sulfur per bushel of grain. It's important to supply the wheat crop with the appropriate amount of nitrogen, phosphorus and potassium to obtain potential yield goals. For efficient nitrogen application, you should split apply the total amount of nitrogen needed for the wheat crop, typically applying 20 to 30 percent of the needed nitrogen in the fall at planting and the remaining balance in the spring.

To maximize wheat yields soil test levels of phosphorus, potassium and lime should be at optimum level. Then apply the recommended amounts of nitrogen, phosphorus and potassium based on yield goal.
