Edaphoclimatic zoning for growing papaya in Valencia Cordoba - Colombia

Abstract

This study involves the evaluation and classification of climate and soil resources in Valencia Cordoba, using geographic information systems. Climate component data from five meteorological stations with records of precipitation, temperature, relative humidity and solar radiation were used. Edafológic component data were obtained from 119 soils analyzes of the growing of papaya. To generate mapping spatial distribution of climatic and soil variables interpolation method of inverse distance weighted incorporated into the ArcMap program was used, this process led to the mapping of variables spatialized on a scale of 1: 250,000. By this method delimited by isolines in climate and soil variables they were calculated areas. To perform the mapping of areas with productive capacity a scale of four categories that involve the variables of soil pH, MO, texture, P y Al, which privileges the A1 was used: Very best, A2: excellent, A3: A4 optimal and slightly: moderately optimal. As a result we obtained the very best areas (A1), representing 4.6% (3,050 ha), located in the northern part of the area that optimal areas (A2) comprise 55% (36,440.7 ha), located in the central sector of the reference area, slightly optimal areas (A3) (23,533.6 ha) and represent 35.5% of the total area, located in the southeast part and 4,7%, (3156.5 ha) has been categorized as slightly optimal (A4) are located in the southwestern part of the study area.
