Which of the following is NOT true of N-P and N-K interactions in soil?
◦ With adequate N and P, there is rapid growth, and the potential response to other nutrients in the soil is greater.
◦ Crop response to N is greatly reduced in low P soils.
◦ Recovery of applied N is increased and residual fertilizer NO3-N in the soil profile is decreased with application of N + P on low P soils.
◦ Antagonistic N-K interactions on grain yield are observed with increasing K fertilization.
