Interrelationship Among Soil Parameters and their Alteration with Seasonal Changes in the Soil of Bawal Town, Haryana

Abstract

Soil is the backbone of agriculture and original source of nutrient that are needed by plants and crops to grow and survival. It is governed by various factors like anthropogenic and natural factors. In this study we aim to interpret the effect of climatic changes mainly seasonal variations on the soil health of Bawal industrial area. Samples were collected at the depth of 15 cm, from three different sites in three different seasons; summer, winter and monsoon. Samples were analyzed for pH, Electrical conductivity (EC), Organic matter (OM), Available nitrogen (N), potassium (K), phosphorus (P) Magnesium (Mg) and Sodium (Na). Results revealed that the OM, K, P, and Na concentration of the soil were found to follow the order; winter>rainy>summer. In contrast to this, Soil pH and Mg content were reported their highest concentration in summer followed by winter and least in monsoon season. EC and N content were found to follow the order; rainy season > winter > summer. Statistical analysis concluded the significant variation in physiochemical parameters of soil with variation in seasons except pH and EC (in summer and winter season). Interdependency of soil parameters was interpreted using multiple linear regression and results highlight that, Soil pH and Mg content were showing a significant linear regression with R2 (0.890). Na showed a significant R2 with K (0.855), P (0.827) and OM (0.803). Nitrogen content had found to show good regression with EC and soil pH. Organic matter and Potassium were also reporting significant R2 values (0.931). Soil fertility was found to get affected by climatic change but the variations could be utilized by cultivating the suitable crops according to soil parameter contents in a particular season.
