Seasonal evolution of the chemical properties and macronutrients of soil in natural stands of Quercus robur L. in Galicia, Spain.

摘要

Substrates under natural Quercus robur stands in Galicia (Spain) are predominantly siliceous, with strongly acidic soils that belong mainly to the Cambisol type with dominant sand texture. This paper presents data of seasonal variation in the concentrations of chemical properties and macronutrients in the upper 20 cm of the soil profile in four oaklands. High precipitation accentuates acidic condition, in spite of, humus high content with a slow mineralization rate. Soil fertility can be considered low, with poor concentrations of potassium, calcium and magnesium, and with higher concentration of phosphorus..
