Evaluación física de tierras agrícolas bajo riego de los sectores el Hatico y el Turmero subcuenca Alto Motatán. Mérida-Venezuela.

Abstract

In the high basins of Venezuelan Andes intensive farming of vegetable crops adapted to its particular agroclimatic conditions, characterized by low use of conservation practices, develops it is necessary to classify the land to determine the best agricultural uses and to formulate conservation practices and resource management soil. The objective of this research was to determine the suitability of the land in El Hatico and El Turmero sectors, Sub- basin of Alto Motatan, Merida State, where producers organized in the form El Rincon del Picacho irrigation committee perform intensive horticultural farming of hillside. It was used the FAO scheme for land evaluation for rainfed agriculture Determined the physical suitability of 7 units of land for current (TUT) land-use types, thus: 3 moderately suitable (A2), 3 marginally suitable (A3) and 1 not suitable (N), for 3 limiting land qualities that can affect the production of crops under irrigation: rooting; pH, nutrients, micronutrients and toxicities; and risk of erosion. Best suitability of land was for the TUT cilantro, garlic, broccoli, leek and artichoke. Based on the results obtained is suggested to agricultural producers implementation of an agronomic management through use of good agricultural practices with fertilizer amendments in adequate amounts, acid soil amendments and use of appropriate amounts of water irrigation for every crop.
