surveying and mapping is an important operation, since it plays a key role in
the knowledge about soil nutrients, properties and how it can be used for
agriculture. This study was carried out in order to map soil chemical
properties and macronutrients status in North, Center and South districts zones
of Gujarat state. Geographic Information System (GIS) was used in this study to
present the secondary data of the soil which were obtained from Anand
Agriculture University (AAU), Gujarat. The major objective of this study was to
analyze & visualize the secondary data of soil through IDW, spatial
interpolation techniques for suitable mapping in a selected North, Central and
South districts of Gujarat state. Various maps showing spatial distribution of
micronutrients and chemical properties for North, Center and South districts
zones of Gujarat state were prepared. These digital maps can be used in
precision farming studies with the application of fertilizers and
micro-nutrients as per the requirement and the recommendations. This approach
is proposed as a method for the evaluation of sustainable soil management
practices such as variable rate of fertilization. This study demonstrates the
usefulness of geo-informatics technology in soil survey as well as applications
of various micronutrients to specific areas based on recommendations.
