The determination of the distribution of the feldspar and clay mineral groups in 650 surface soils of the various counties in Pennsylvania indicates that the variations noted point toward important relationships between mineral composition and agricultural value. The most valuable soils agriculturally are those where the feldspar of the very fine sand fraction is greater than 17% and the predominant clay mineral is a low fixer of potassium. This study indicates that the mineral composition of soils should be taken into account when soil studies involving fertilization application, maintaining soil productivity and soil description are undertaken.
