When determining the margin, two types of inputs are considered, variable inputs and fixed-price inputs.*
VARIABLE INPUTS
Corn: diesel fuel, interest, diammonium phosphate (DAP), potash**, urea
Soybeans: diesel fuel, interest, DAP, potash**
Wheat: diesel fuel, interest, monoammonium phosphate (MAP), potash**, urea
FIXED-PRICE INPUTS
While fixed-price inputs impact the amount of insurance coverage, only price changes for variable inputs determine whether an indemnity is paid along with county yield changes and changes in price for the commodity.
Corn: preharvest machinery, seed, lime, herbicide, insecticide
Soybeans: preharvest machinery, seed, lime, herbicide
Wheat: seed, maintenance, chemicals, lubrication
*Land, rent and labor costs are not included.
**The price of potash won’t change from fall to spring because there is no current viable trading market.
