Abstract
The agricultural land suitability analysis is a way of assessing the suitability of cropland. The aim of this study is to assess the suitability of lands for agriculture in Nalanda district of Bihar. The land suitability assessment was performed using the Analytical Hierarchy Process (AHP) method. The parameters like soil texture, soil pH, slope degree, elevation, aspect, drainage density, river basin, distance to road, and land use land cover were used. For determining the weights of the parameter, expert’s opinions were consulted, and the agricultural land suitability map was generated. Furthermore, maps were divided into five categories according to the classification enlisted by the United Nation Food and Agriculture Organization (FAO). In addition, the THOMAS SAATY table was referred for ranking the parameters used for the analysis of the suitability of the agricultural lands. Based on the ranking of the parameters, several techniques are adopted by the farmers to improve productivity. Additionally, the methodology is applied to evaluate and hence enhance the soil fertility of the agricultural lands in Nalanda district.KeywordsLand suitabilitySuitability parametersGIS toolsAHP model
