Evaluación de la fertilidad de suelos en la granja escuela Casiciaco Haren Alde

Abstract

The purpose of this study is to know the fertility of the different lands of the farm, by means of the sampling of soils and pits, in different areas, destined to paddocks, crops and soils at rest, which gave an idea of the level of deficiency or sufficiency of the major and minor elements of the floors. To do this, they chose two areas of pastures, two for agricultural use and two trees (coffee and forest), with different pioneer species, shrubs and trees, in a state of secondary ecological succession. For each zone sampling was carried out and pits were made in the areas of pasture with cattle and in the coffee area. No comparisons were made between the different sections; only comparisons were made within each area. We found deficiencies in major elements, and some minor ones, with an acidic pH, product of the natural conditions of the place, and the sowing of crops, cattle raising and construction of infrastructures; these activities have caused erosion and compaction of the land. Currently, there was no study of soils on the farm, so it was necessary to start this research that will indicate the state of soils related to fertility; this will serve for the integral planning of the farm.
