Abstract

Purpose: Human activities generate substantial waste, often relegated to landfills or incineration. Composting offers a valuable alternative, transforming waste into organic fertilizers that can improve soil health. This review examines the multifaceted influences of compost application on soil properties, the associated agricultural and environmental benefits.

Methods: A comprehensive literature review was conducted, analyzing numerous research articles focused on compost application in agricultural soils. The review prioritized studies investigating the direct and indirect effects of varying compost application rates on a range of soil properties. The search encompassed databases and scientific journals related to soil science, environmental science, and agriculture. 

Results: The reviewed literature consistently demonstrated that compost incorporation positively influences several key soil properties. Compost application generally led to a reduction in bulk density, indicating improved soil structure. Furthermore, it enhanced water infiltration and hydraulic conductivity, promoting better water management. Compost also increased soil water content and the availability of plant-available water, benefiting plant growth. The review highlighted that compost application generally has positive effects on agricultural and environmental soils.

Conclusion: Composting offers a sustainable waste management strategy with significant potential for soil improvement. The reviewed evidence supports the widespread use of compost as a soil amendment to enhance soil physical properties, water relations, and potentially other soil chemical and biological properties. These improvements contribute to enhanced soil health, sustainable agriculture, and

environmental protection, particularly in the context of degraded soil remediation. Further research is encouraged to optimize compost application rates for different soil types and cropping systems.
