Spatial analysis in decision-making on agriculture activities
Abstract
Geoinformation technologies (GIS) play an important role in precision agriculture and the organization of smart agriculture. This can impact deeply the analysis of the state of agricultural lands, mainly irrigated lands, and find a positive solution to the problem based on digital data consisting of different thematic layers. In this research, spatial analysis of agro-ecological conditions was carried out in order to establish effective precision agriculture in the Pakhtazor massive of the Mirzachul district of the Jizzakh region. Representing agro-ecological (soil, climate, groundwater, weather) and social (population, settlements, roads for transport) factors that directly affect the efficient production in agriculture through geospatial analysis and thematic maps were developed. In the process of creating thematic maps and analysing the data, spatial analyses such as IDW, Euclidean distance, and Kernel density were performed using ArcGIS software. As a result of spatial analysis, soil quality was assessed with an average value. Groundwater level and mineralization were in normal condition with 2-2.5 meters and 0-3 gr/l respectively. Infrastructure, irrigation-drainage system, and weather are sufficient to carry out effective agricultural activities, especially crop cultivation.
