Sustainable Farming Practices: A Comprehensive Review of Their Impacts on Crop Productivity and Soil Health

Abstract

Soil health is fundamental to sustainable agriculture, underpinning crop yield, environmental resilience, and long-term ecosystem stability. Modern agricultural practices, marked by excessive use of pesticides and fertilizers, monoculture, and high ploughing, have led to significant soil deterioration, necessitating innovative approaches to restore and maintain soil health. This study analyzed sustainable approaches to augment soil health and boost crop quality in contemporary agricultural systems. Maintaining the physical, chemical, and biological properties of soil is crucial for its health, attainable via several agronomic methods. Methods including crop rotation, cover cropping, no-till farming, carbon farming, conservation agriculture (CA), and the use of organic amendments were examined for their efficacy in restoring soil structure, enhancing organic matter, and fostering biodiversity. These projects aim to conserve and improve soil ecosystems by integrating agricultural techniques with ecological principles, so assuring long-term production and environmental stability. Improving soil health will enhance soil functions, reinforcing the notion that augmenting soil organic carbon (SOC) is essential. This research established that conservation tillage is superior to conventional tillage regarding soil health, a subject that remains contentious among scientists and farmers, and that different tillage methods demonstrate unique interactions. These solutions would improve soil health by integrating the management of plant, soil, microbial, and human interactions.
