Estimation of temporal and spatial changes in micronutrients in the soil using geostatistical analysis

Abstract

Investigation of temporal and spatial changes is essential in soil because of its heterogeneous, diverse and dynamic system. In present paper, content of some important major micronutrients namely zinc, boron and iron were estimated at different unsampled locations in Sevapuri block of Varanasi district, Uttar Pradesh by using some Geostatistical analysis. After normalizing the data, geo-statistical analyses were used to illustrate spatial variation and then spatial distribution maps of micronutrients were prepared. On the basis of these maps amount of micronutrients at unsampled location were estimated by using data of sampled locations.
