People Also Ask about

How much P and K does corn need?

A typical fertilization of macronutrients for corn in the United States is 180 lb of N, 90 lb of P2O5, and 160 lb of K2O per acre. Phosphorus, although required, is often overlooked in maintenance fertilizer applications, which can limit corn yield potential.

What are the dry blends for corn fertilizer?

Common dry blends are 20-10-10, 10-20-20, 8-32-16, and 6-24-24. With dry-blended fertilizers, segregation can occur when these materials are transferred from a bin to a truck or a truck to a bin. A compound fertilizer is typically a solid product that contains multiple nutrients within each granule.

What are the P and K requirements for corn?

A typical fertilization of macronutrients for corn in the United States is 180 lb of N, 90 lb of P2O5, and 160 lb of K2O per acre.

What does corn need for fertilization?

Thus, a good starter fertilizer might range from a ratio of 1-4-0, 1-3-1, 1-3-3, to 1-1-1, depending on the rate of fertilizer required. Do not apply more than 80 to 100 pounds per acre of N + K2O in the starter band. For example, 350 pounds per acre more of 10-20-20 can result in seedling injury.

What are ideal P and K levels in soil?

The 23 ppm P value is in the “optimal” range, between 20–40 ppm. Potassium is reported as 100 ppm in Table 1. In addition to the potassium (K) soil test result, cation exchange capacity (CEC) is also used to develop the K recommendation.
