Agriculture, both crops and livestock, depletes soils of mineral nutrients, because of the removal of nutrients contained in the produce sold. Since the 1950's the increase in farm productivity and efficiency has not always resulted in a corresponding increase in the replenishment of mineral nutrients to the soils through commercially available means. This is because many growers in the US do not have sufficient management expertise to account for or replace all plant nutrient elements removed. In public range and forest tracts leased by ranchers, there has been relatively little effort to replace minerals removed by livestock. Consequently, there is evidence of widespread mineral nutrient depletion in U.S. farm and range soils.
