The article addresses the issue of developing a model for optimizing the use of agricultural land. The negative impact of environmental factors of the Aral Sea requires more labor in obtaining high yields from agricultural lands in the region. The research aims to increase land use efficiency based on the placement of agricultural crops through optimal solutions. The main goal of optimization is to minimize the resources expended in the cultivation of agricultural products. The agricultural land use optimization model was implemented using the GIS and linear programming simplex method, and the results are depicted on a 1:10 000 scale map. The farm lands of Chimbay district were selected as the object of the research and 3 different solutions for the placement of crop types were proposed. Scenarios for the placement of agricultural crop types were implemented through the ArcGIS 10.6 program and the ArcPy application. The amount of resources used to grow the crop types on the selected 100 hectares of irrigated land was calculated. Through this optimal solution, the resources spent on the cultivation of various crops have been reduced by 11%. The developed optimization model will significantly help to increase the efficiency of agricultural land use in the correct placement of agricultural crops, taking into account environmental and economic factors.
