THE STUDY OF SOIL HUMUS CHANGES WITH THE HARRINGTON “DESIRABILITY” FUNCTION

Abstract

The potential utility of the Harrington “desirability” function is examined in the assessment of changes in soil humus content using spectrophotometric data. The influence of external factors, such as sun angle, soil moisture content, and degree of soil cultivation, on spectral brightness coefficients is analyzed. The applicability of this method when there is only a small volume of experimental data is noted.
