NE Iowa | The N in DAP is much more stable then the N in urea. Not incorporating it is no problem. I don't take credit for the N if fall applied but if applied in he spring I certainly do. I apply enough DAP in the spring for both the corn and beans in my rotation because the N in DAP is basically free. My source of fertilizer used to also stock TSP (0-45-0) years ago but it is now exactly the same price as DAP so they quit. | |
