Nutritional data on pasture quality have been correlated with chemical data on related soils to provide criteria for selecting forested or other nonagricultural sites potentially capable of producing pasture of adequate quality for grazing animals in eastern Peru. With the selection of crude protein as being of first importance, a minimum level of 3% organic matter in a soil identified two‐thirds of the soils investigated that produced pastures containing a concentration of 8% or more crude protein in the moisture‐fee forage. Application of the additional criterion for adequate P in the forage, 0.02% of soil N, identified 80% of the soils producing adequate protein. Regression coefficients for concentrations of plant constituents — P, Co, Cu, Mn, Ca — and crude protein on soil measures, pH, total N, organic matter, exchange capacity, and exchangeable Ca are presented.
