Resource Conservation Technologies in Sustainable Crop Production: A Review

Abstract

In modern times, traditional farming methods are unsustainable and negatively impact the environment. Environmental deterioration mostly manifests as nutrient depletion in many emerging nations, which lowers the capacity for food production. Resource conservation technologies (RCTs) adoption and resource efficiency are challenges. Conservation agriculture refers to cropping systems that boost biodiversity, maintain a permanent soil cover, minimize soil disturbance, diversify crop species, and promote natural biological processes both above and below the soil. The four guiding concepts of conservation agriculture are reducing mechanical soil disturbance and immediately planting tillled soil, which enhances soil health and organic matter content; utilizing crop waste and cover crops to increase soil organic matter. This protects the soil's surface, preserves water and nutrients, and encourages soil biological activity; crop diversification in associations, sequences, and rotations to improve system resilience, which in turn lowers tillage and retention by disrupting pest and disease cycles; and controlled traffic that loosens soil compaction. Reduced tillage, residue management, laser land leveling, site-specific nutrient management, and other techniques are examples of these RCTs. By reducing the consumption of fossil fuels, these technical elements also contribute significantly to the reduction of greenhouse gas emissions. In order to attain intensive and sustainable crop production in various agro-ecological situations, these new technologies must be adopted under a diversified cropping system.
