Effect of NPK and other Micronutrient on Paddy Soil

Abstract

Soil quality is crucial for the fulfilment of food requirement of huge population of developing countries like India. The goal of the current investigation was to assess the impact of crop harvesting on soil with special reference to paddy crop. To meet the study's goals, fifteen locations were chosen from Mul tehsil in Chandrapur District (M.S.), India. The study used a systematic sampling and samples were chosen grid-wise based on how the population cluster used the rice that was grown. During the study, numerous markers connected with soil quality were inspected, including pH, electrical conductivity (EC), nitrogen, potassium, phosphorus, water holding (WH), zinc (Zn), copper (Cu), iron, and natural carbon (OC). The results obtained indicate that the soil of the study area was saline at more than 75% of the sampling sites. Greater soil fertility is found at more than 81% of the sites as indicated by OC values. The soil was observed from acidic to alkaline in nature. The soil's suitability for paddy crops is also indicated by the levels of iron, zinc, copper, and nitrogen. Most of the physical characteristics and micronutrient content dropped after the harvesting of rice crop except copper.
