Estudio de suelos naturales y agrícolas gallegos y de las relaciones entre su contenido en nutrientes (III). Calcio y magnesio
[EN] The relationship between calcium magnesium in natural sloping soils and granitic parent material to agricultural soils of the valleys was studied. No accumulation of both cations was found in the natural profiles. The content of Ca and Mg in cultivated soils is greater than in natural ones. The...

| Sumario: | [EN] The relationship between calcium magnesium in natural sloping soils and granitic parent material to agricultural soils of the valleys was studied. No accumulation of both cations was found in the natural profiles. The content of Ca and Mg in cultivated soils is greater than in natural ones. The correlation coefficient was determined being all r values negatives for calcium. The better probability corresponds to the surface horizons. Linear regresion of the variations are given. The correlations coefficient for magnesium varies with the depth of the sample being the maximum the B horizon. There are a relationship of the calcium and magnesium content in natural soils to those of the valley. Well treated cultivated soils have smaller magnesium content, given very high ratio Ca/Mg. |
