Conservation Agriculture is a Sustainable Approach for Future

Conservation agriculture (CA) embodies a forward-looking and sustainable approach to cultivation. It is characterized by a farming system that prioritizes sustainability through practices such as minimizing soil disturbance, maintaining permanent soil cover, and implementing crop rotations. The overarching goal is to preserve soil health and enhance productivity. This method emphasizes the optimization of natural resources, the reduction of inputs, and the enhancement of nutrient utilization efficiency. The primary focus of this review article around conservation agriculture (CA), characterized by revolutionary practices involving minimal soil disturbance (no-till, NT) and the maintenance of continuous soil cover (mulch). Agriculture heavily relies on cultivation and tillage practices. The review first explores the advantages of conventional cultivation techniques before the introduction of conservation tillage (CT), a method that originated in response to the American dust bowl of the 1930s. Subsequently, the review delves into the benefits of CA, considered an improvement over CT. The incorporation of no-till (NT), mulching, and related innovations significantly enhances soil qualities and various biotic factors within the framework of CA. Nevertheless, the promotion of Conservation Agriculture (CA) technologies encounters several challenges. These include the absence of suitable seeders tailored for small-scale farmers, conflicts between the use of CA and livestock feeding for crop residues, the practice of burning crop residues, a scarcity of skilled manpower, and the challenge of overcoming traditional attitudes towards tillage. Drawbacks of conservation agriculture encompass factors such as limited adoption, insufficient knowledge and skills, reliance on herbicides, and initial investment costs, among others.
