This Paper Speaks About Site Specific Sol And Crop Management The soil varies from place to place and many of its properties change from time to time. The variation is due to space and time variations of edaphic, biological topographic, anthropogenic characters and climate. The change is influenced by different interactions of soil forming factors along with space and time. Information about soil variability is important in ecological model designing, environmental forecast, precision agriculture and natural resources conservation. There is a need in modern agriculture in understanding spatial and temporal variations within a field. Understanding such variation is essential for site specific soil and crop management, which requires the portraying of management areas.
