Data on soils are the most crucially needed information for proper planning of agricultural development. Soils data can be generated by different organizations but the reliability, quality and availability of this information is the main concern for data users. Collecting all soils data from different organizations and putting it in one central database can facilitate ease of availability. this can be achieved by establishing a national soils database centre. The advantage of a database is the ease at which soils data can be entered, updated, retrieved, and manipulated within a short period of time. This can also difinitely promote the standardization of data format. It also facilitates the accessibility and data exchange mechanisms among data generators and users. Geographic information system (GIS) is a system which is used for data entry, updating, retrieval, manipulation etc., of a georeferenced data i.e. digitized map. Soils data referred to is the characteristic of a soil of a certain area or soil characteristics of a single profile data i.e. point on the earth surface. The area or the single point can be identified by place name, latitude and longitude, UTM etc., systems. These locations or point can be linked with the GIS database so that soil data can be manipulated using GIS technics. This paper mainly discusses the problems faced in the establishment of a soils database at the Land Use Planning and Regulatory Department (LUPRD) of MNRdEP. It also shares the experience of LUPRD in using GIS for soil data manipulation for the purpose of land evaluation assessment.
