Crops include corn,  soybeans, oats, grain sorghum, barley, wheat, hay, rye,  flax, and cotton.  Budgets show the quantity and value of  specific preharvest and harvest inputs, total preharvest  costs per acre planted, and total variable costs per acre  planted.  Detailed breakdowns of crop yields and rates of  fertilization are also included.},
