Abstract

Nitrogen, phosphorus, potassium, silica, iron, alumina, and base-exchange capacity were determined on nine Iowa soils and correlations made in an attempt to devise a system of soil mapping to be used when these constituents of the soil and soil extract were known. The results secured indicate a definite relationship between these constituents in each of the soils studied. However, no apparent relationship existed between the variations and soil type. The P₂O₃ content of all soils was found to vary directly with the base-exchange capacity of the soil.
