Yield Monitor Maps for P and K Fertilizer Rate Prescription Maps??

Soil sampling time may be in short supply when crop harvest is to be followed by the establishment of a succeeding crop. Soil test results are not always timely, further delaying prescription map development. Due to the expense, grid, or zone, sampling is often done only every 2 to 4 years, which raises the question of how much fertilizer is to be applied in other years.

Generally, the area of plant death is larger than we initially estimate. If the water was over the ears for about 24 hours, then the ears are lost. They very likely have started to rot by now.

Dry Weather Effects on Corn at Early Growth Stages
