Climate change and environmental degradation have contributed in compromising the soil nutrient integrity of cocoa farmlands, yet sustainable nutrient recycling innovation in cocoa waste management has received less research attention. Utilizing experimentation methodology in an agroforestry system composed of cocoa (Theobroma cacao L.) and a Nitrogen-fixing Gliricidia sepium (Jacq. Kunth ex Walp.), the study examines how the soil nutritional level of farmland can be enhanced. The study confirms the proposition that the rate of decomposition and nutrients release from an innovative mixed waste sample (60% cocoa waste and 40% gliricidia waste in this case) is significantly higher in comparison with the traditional cocoa waste only sample. The results further established that innovative mixed waste sample had a faster decomposition rate (no biomass left at 216 days after laying) as compared to traditional cocoa waste which fully decomposed at 277 days after laying. A difference of 51 days after laying justifies the waste mixture decomposition as a sustainable nutrient recycling innovation within cocoa agroforestry waste management context. These results have implications for agroforestry waste management, soil nutrient recycling and cocoa industry performance.

迈向可持续农林业管理:通过可可混合废物提高营养土壤价值

气候变化和环境退化已经损害了可可农田的土壤养分完整性,但是可可废物管理中可持续养分循环利用的创新受到了较少的研究关注。在由可可(Theobroma cacao L。)和固氮香根草(Jacq。Kunth ex Walp)组成的农林业系统中利用实验方法),研究探讨了如何提高农田的土壤营养水平。这项研究证实了这样的主张,即与传统的仅可可废物样本相比,创新的混合废物样本(在这种情况下为60%可可废物和40%芦苇属废物)的分解和养分释放速率显着更高。结果进一步证明,与传统可可废物在铺设后277天完全分解相比,创新的混合废物样品具有更快的分解速率(铺设后216天没有生物质残留)。放置后的51天之差证明了可可豆农林业废物管理环境中废物混合物的分解是一种可持续的养分循环创新。这些结果对农林业废弃物管理有影响,
