SPATIAL ANALYSIS WITH GIS MAPPING OF FUNGICIDE CONSUMPTION IN AGRICULTURAL AREAS

Abstract

The development in agriculture has gradually increased the use of fungicides in Turkey. Fungicides negatively affect the life conditions of living organisms in water, air and soil environments. It's important to be aware of the right amounts of chemicals to be used in certain periods. The aim of this study is to spatially determine the amounts of fungicide consumption using Geographical Information System (GIS) mapping, and also to determine the level of distribution in Nevsehir province and districts during the 2010-2014 period. The data obtained from the Turkish Statistical Institute and Nevsehir Directorate of Provincial Food Agriculture and Livestock has been evaluated by the help of Inverse Distance Weighting (IDW) method in the GIS. While the highest amount of fungicide consumption was observed to be 250.0 tons in 2010, the lowest amount of fungicide consumption was determined to be 179.78 tons in 2013. When examining the spatial distribution of fungicide consumption, the highest consumption intensity was observed in the North (Kozakli district) and Northwest (Hacibektas district) of Nevsehir province, and the lowest consumption intensity is determined to be in the Southern (Central district) and South-western (Acigol district) agricultural areas through the whole period. According to the spatial distribution, the highest concentration intensity has been observed in Kozakli and Hacibektas agricultural areas in all years.
