Cropping Systems

Cropping Systems Research at WSU

The term cropping system refers to the crops and crop sequences and the management techniques used on a particular field over a period of years. Long-term cropping systems research projects generally involve a team of scientists of different disciplines working together to answer questions and solve problems. Dryland cropping is practiced in many diverse agro-climates in the Inland Pacific Northwest where average precipitation ranges from 6 to 26 inches per year. Common objectives of cropping systems research projects conducted by WSU and USDA-ARS scientists are to increase crop diversity with non-cereals such as oilseed and legume crops, intensify rotations (i.e., less fallow), maintain or increase soil quality, reduce or eliminate tillage, and sustain economic profitability for farmers.
