Recent research highlights the benefits of using biochar-poultry manure compost in agriculture. This innovative composting method involves combining biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More, a carbon-rich material derived from organic matter, with poultry manure. The mixture alters temperature and nitrogen dynamics during the composting process and improves crop growth, specifically in potatoes.

The study found that adding biochar to poultry manure compost helped regulate temperature during composting, keeping it within optimal ranges for microbial activity. This temperature control is crucial as it prevents overheating, which can inhibit the decomposition process and harm beneficial microbes. Furthermore, biochar enhances nitrogen retention in the compost. Nitrogen is an essential nutrient for plant growth, but it is often lost as ammonia gas during composting. Biochar’s porous structure traps ammonia, reducing nitrogen loss and making more available for plant uptake.

Field tests showed that potatoes grown in soil amended with biochar-poultry manure compost exhibited significant improvements in growth compared to those grown with standard compost. The biochar-enhanced compost improved soil structure, increased water retention, and provided a slow-release source of nutrients, leading to healthier and more robust plants. The enhanced nutrient availability and better soil conditions resulted in higher potato yields.

These findings suggest that integrating biochar into poultry manure composting could be a valuable strategy for sustainable agriculture. It offers a way to manage waste effectively while improving soil health and crop productivity. As farmers seek eco-friendly methods to boost yields, biochar-poultry manure compost presents a promising solution with multiple benefits for the environment and food production.
