One reason to contract crop sales is to capture value in an identity preserved system

Identity Preserved Crops
There is something about the variety that is worth remembering.
Variety identification is “preserved” throughout the growth, transport, and processing cycle.
the “something” is what you contract
ID includes prevention of contamination

A New Way of Thinking
A specified product, not a commodity
Consider what happens after the farm gate, not just in the field
Value is in quality, not just yield

Commodity Grain Grading
US Federal rules and regulations
Established to aid and standardize grain commerce
Emphasizes speed of process and uniformity of commodity
Grain price is reduced by failing grade

Identity Preserved Crops
US Federal No standard rules and regulations
Established to enhance specific trait aid and standardize grain commerce
Emphasizes speed of process and uniformity of commodity uniqueness
Grain price is decreased increased by increased quality and lost completely by failing grade

Identity Preserved Crop Management
Use production practices that enhance the “something” that makes the variety useful
Try to limit events and conditions that decrease the “something” that makes the variety useful
Limit contamination (0% contamination is an expensive dream)
