It includes all vegetation, whether or not it is palatable to grazing <br />animals. It includes the current year's growth of leaves, twigs, and fruits of woody <br />plants. It does not include the increase in stem diameter of trees and shrubs. It is <br />expressed in pounds per acre of air-dry vegetation. In a normal year, growing <br />conditions are about average. Yields are adjusted to a common percent of air-dry <br />moisture content. <br />In areas that have similar climate and topography, differences in the kind and <br />amount of vegetation produced on rangeland are closely related to the kind of soil. <br />Effective management is based on the relationship between the soils and <br />vegetation and water. <br />Rating Options <br />Units of Measure: pounds per acre per year <br />Aggregation Method: Weighted Average <br />Component Percent Cutoff.
