[ul][*]Divide field into 4, measured, equal sized foodplots. This is for managing planting density, herbicide rates, fertilizer application, ect.[*]Start the fields in a rotation, in order, 1) RR corn 2) RR soybeans 3) clover 4) clover. Each field is in a different part of the rotation. When clover is planted, that field sits for two years before getting plowed under to plant corn in the rotation. So each spring you are only working 3 of the 4 plots. Rotating helps control weeds, disease, and soybeans/clover put Nitrogen in the ground for the corn.[*]Variations might include putting some rape/brassicas in with the planting of clover.[*]Or adding a 5th field with a summer planting then a fall planted winter wheat/clover plot added to the rotation.[/ul]
