Assessment of Micronutrient Deficiencies in Agricultural Soils of Hasanganj and Auras Blocks, Unnao District, Uttar Pradesh, India: Implications for Sustainable Farming

This study evaluated the status of essential micronutrients in the soils of Hasanganj and Auras blocks in Unnao district, Uttar Pradesh, India, during 2020–2021. A total of 200 surface soil samples from five villages in each block were analyzed for zinc, boron, copper, manganese, and iron content. The findings revealed significant deficiencies, particularly in zinc (39.5%) and boron (32.5%), with potential implications for crop productivity and soil health. The study emphasizes the urgent need for balanced nutrient management and soil-specific fertilizer recommendations to address these deficiencies and support sustainable agricultural practices. These results provide a valuable baseline for future research and policy interventions aimed at improving soil fertility and food security.
