A multivariate approach to the response of lucerne plants to varying soil conditions in pots.

Abstract

Five levels of lime, five levels of P and a constant level of K were applied to soil in pots to create a range of soil conditions. Factor analysis was used to relate a number of soil test variables to a few factors. Seventeen of the eighteen recorded soil variables were closely correlated with six factorsLanguage: English
