Soil Health and Plant Nutrition: Advances in Fertilizer Management for Sustainable Agriculture

Abstract

Soil health is a cornerstone of sustainable agriculture, directly influencing plant growth, nutrient availability, and overall ecosystem function. This study explores recent advancements in soil health management and plant nutrition, focusing on the role of soil fertility and the efficient use of fertilizers. The paper reviews modern fertilizer technologies, including controlled-release fertilizers, nutrient-dense soil amendments, and organic fertilizers, and evaluates their impact on crop yields and soil microbial health. It also examines the relationship between soil structure, water retention, and nutrient cycling in maintaining plant nutrition over time. Through field experiments and case studies, the research shows how soil health management strategies can improve crop productivity while reducing environmental pollution from excessive fertilizer use. The study concludes by advocating for integrated approaches that combine soil health monitoring, precision farming techniques, and sustainable fertilizer application practices to enhance soil quality and optimize plant nutrition.
