Coefficient of correlation for soil physico-chemical parameters

P.G.Smitha1, K.Byrappa, Lancy D'Souza

Soil samples fromtwenty agricultural fields of Bantwal taluk of Southwestern Karnataka, India, were subjected to analysis of physico-chemical parameters like, soil texture, pH, electrical conductivity, organic matter content, total nitrogen, P, K, Na,Ca, S, trace elements like Fe,Mn, Zn, Cu,Mg, and B. Simple correlation or Karl PearsonÂ’s coefficient of correlation was established between the parameters and in this paper the results are discussed with respect to the statistical significance of the correlations observed.
