Case study on the soil physical parameters disparity and NPK concentrations in regions found in and around Pachapalayam, Coimbatore, Tamil Nadu.

Abstract

Deficient soil fertility is a major constraint in crop productivity. Soil characteristics such as pH, bulk density, electrical conductivity, moisture content, etc. play a major role in the health and yield of crops. Major nutrients such as Nitrogen (N), Phosphorus (P) and Potassium (K), are essential for the growth and yield of the crops as well. On account of the importance of soil physical properties and NPK concentration on the soil dynamics and plant development respectively, the study area was spatial distributed and geo-statistically analyzed to produce contour maps that can be used by decision makers in farm management for increased crop productivity.
