Correlation Between Plant Analyses and Soil Tests in New Mexico1

M. R. Pack and R. S. Gomez2

ABSTRACT

As part of a plant nutrient survey of New Mexico, samples of cotton leaves and alfalfa were collected from a wide variety of soils throughout the state. The soil was also sampled at each location. Within each set of samples (cotton and alfalfa) the following comparisons were made by means of correlation analysis: plant P with CO2-soluble soil P, NaHCO3-soluble soil P, H2O-soluble soil P, and Bray's adsorbed soil P; plant N with total soil N and soil organic matter; and plant K with CO2-soluble soil K. Significant positive correlations were found in all comparisons except those involving N. The degree of correlation was used as a basis for evaluating the different soil testing procedures.

Of the four P tests that were tried, H2O-soluble soil P showed the best correlation with plant P. There was a better correlation between the H2O-soluble soil P and the NaHCO3-soluble soil P than between the results of any other two of the soil P tests. Apparently, neither total soil N nor soil organic matter gives a reliable indication of the available N in New Mexico soils. The correlation between plant K and CO2-soluble soil K was fair.
