Indice de correlación entre el carbono orgánico y nitrógeno en suelos de la cuenca del Ebro

Abstract

[EN] In a comparative study of the conditions of soils, the regresion lines of 283 pairs of values for irrigated soils and 295 pairs for dry-farming soils were analyzed. The average of the relation C/N is 8,04 for the dry-farming soils and 6,87 for the irrigated soils. The correlation coefficient is r=0,923 for dry-farming soils and r=0,875 for irrigated soils. The significance of these results is very high. Under these circunstances one may conclude that, for the soils studied, it is possible to establish the nitrogen content after the amount of the organic carbon.

[ES] En este trabajo se estudia el coeficiente de correlación entre los contenidos de carbono orgánico y nitrógeno en suelos de regadío (283 pares de valores) por un lado, y en suelos de secano (295 pares de valores) por otro, en el Valle del Ebro.
