Abstract

The present study highlights the physiochemical properties and a methodology developed for mapping spatial variability of available macronutrients of soils of mango (Mangifera indica) orchard in Gandhi Krishi Vignana Kendra University of Agricultural Science, Bengaluru. The soil samples were collected from six different sites of the mango orchard (shaded, unshaded, moist, unmoist, aged, new sapling) covering an area of 16.7 ha. This study of soil is based on the various parameters like pH, total organic carbon, Macronutrients (Phosphorous, Potassium, Boron, Calcium, Magnesium, Sulphur, Sulfate, and Phosphate). This study revealed the spatial variability of nutrients at different levels, which indicates the quantity of nutrients levels were low, medium and high content to study the effect of nutrients to increase the percentage of yield crops.
