Advances in Soil Nutrition: The Role of Micronutrients in Crop Yield Enhancement in India

Abstract

Micronutrients, although required in trace amounts, play a crucial role in crop growth and development. This paper explores the role of micronutrients in enhancing crop yields in India, particularly in rice and wheat production. The study reviews the current state of soil micronutrient deficiencies in Indian agriculture, including iron, zinc, and copper, and their impact on crop productivity and nutritional quality. Through field studies and soil analysis across multiple states, the paper identifies regions most affected by micronutrient deficiencies and examines the effectiveness of various soil amendments, such as micronutrient fertilizers and foliar sprays. The research also investigates the role of integrated nutrient management (INM) in addressing both macronutrient and micronutrient deficiencies in soil. The findings suggest that the application of micronutrient fertilizers, combined with balanced nutrient management practices, can significantly improve crop yields and food security. The paper concludes with recommendations for policy interventions, including the promotion of soil testing, farmer education, and the development of affordable micronutrient fertilizers to ensure sustainable agricultural practices in India.
