Abstract

Geographic Information System (GIS) is a data-based management tool used in assembling, storing, retrieving, analyzing and displaying geographically referenced information. Its vast applications in agriculture include data inventory, analysis and management. It can provide analytical capability for precision agriculture.

Recent advances in GIS and its allied technologies like remote sensing (RS) and global positioning system (GPS) allow fast and site-specific spatial data analyses for a district wide crop-soil suitability, transport network accessibility, planting/harvest scheduling, identification of areas prone to drought, flooding and erosion, soil fertility mapping, cropped area estimation and yield forecasting. As a tool in management and decision making, GIS could effectively be used in locating agrotechnology recommendation domain, crop modeling and scenario-building (what if?) for various land use alternatives.

Some major applications of GIS in Soil Science are presented in this lecture. These include inventory and mapping of geo-referenced land attributes (soil types, slopes, elevation, land use, climate), delineation of land management, crop suitability analysis, soil fertility mapping, among others. A power point presentation composed of seventy two (72) slides is also prepared
