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.
Evaluación y clasificación de tierras agrícolas para la conservación de suelos en áreas montañosas tropicales, subcuenca Alto Motatán, Mérida-Venezuela

A methodology to evaluate and classify land in mountain areas for the purpose of soil conservation, based on the soil productivity index (IP) and soil erosion risk (IRE) were applied. The study area includes plots of Los Caracoles (1.05 has) and El Rincon del Picacho (5,95 has), Alto Motatan subbasin, Merida State, Venezuela. Land suitability and classes and soil conservation requirements were determined. El Rincon del Picacho soils showed better aptitude soil productivity in comparison with Los Caracoles, for both the IRE was a moderate aptitude. The plots are classifi ed as lands in reserve (mainly in Los Caracoles) and in sub-critical condition (mostly in El Rincon del Picacho). The utilization of practices for soil conservation, combining intensive practices of management, management of vegetable cover and moderate practices of control of runoff mountainside are recommended.

The located cotaneous leishmaniosos is a clinical entity of a protozoosis caused by the of a flebotomine female insect, previously infected by a parasite of the leishamnia genre. In Trujillo, Venezuela, this illness has a high epidemic risk for its urban and rural presence, presenting a monthly variation average of 143 cases, calculated in the base of voluntary attendance to a medical clinic for the investigation and diagnostic of metaxenic illnesses at the Research Center “Jose Witremundo Torrealba”. The present work presents the result of a descriptive retrospective study carried out in a sample of 1600 interviews with parient and a door survey in rural towns of this state, with the objective of determining the use and type of homemade treatments that can interfere with the chemo therapy, as well as to verifying the clinical cure with these treatments and to determine the casual agent of the lesion by means of inmunologics (IDR), serologics (ELISA) and moleculars techniques (PCR) and parasitic cure’s possibility. We find twenty-six plants with an importance bigger than 50% of use, in 360 detected; the plants were grouped according to the Rabeteau’s system, in four groups of medicinal plants. It is pointed out their common name and the way of use of each one of them. We confirm the clinical cure by these treatments and to Leishmania (v) braziliensis as casual agent of the current lesion, finding a 32% of parasitic cure and 2% of reactive on skin. We conclude that it becomes necessary a study experimentally designed with the plants that are mostly used the communities
