What Are Districts?

Agricultural Statistics Districts (ASD) are defined groupings of counties in each State, by geography, climate, and cropping practices. The geographic attributes include soil type, terrain, and elevation (mountains). The basic components of climate are mean temperature, annual precipitation and length of growing season. These factors influence the crops grown, the need to conserve soil moisture, and the use of irrigation (cropping practices).
