“…Further, forest topsoil provided the least stover yield probably because of high soil sodium and clay content and microclimate which limited the photosynthetic capacity of cassava leaves for assimilate translocation into sink tissues. Sonti et al [16] argue that while urban forest patches can provide critical ecosystem services, regenerate native tree species and contribute significantly to environmental sustainability, there can be short term soil and microclimate-induced stresses which can affect the photosynthetic capacity and growth of succession plants and crops introduced to the forest environment.…”

Mining operations in Ghana's Forest-Savannah Transition Zone have caused widespread land degradation, jeopardizing ecosystems, food security, and agroecological sustainability. In response, we conducted an experiment to evaluate the effects of biochar and poultry litter amendments on cassava (Manihot esculenta) growth, nutritional quality, and heavy metal accumulation at an illegal mining-degraded site in the Amansie Central District of Ashanti, Ghana. The experiment included five treatments: biochar (10 ton/ha), poultry manure (10 ton/ha), a biochar-poultry manure mix (1:1 ratio, 10 ton/ha each), and two control groups (degraded and forest sites). The combined biochar and poultry manure treatment yielded the highest cassava stover biomass (22.9 ton/ha) during the first year. Nutritional characteristics of cassava such as %carbohydrate, %protein and %total ash tubers were influenced by treatment amendments. Additionally, biochar and poultry manure reduced the accumulation of Arsenic (As) by 168.9% and Lead (Pb) by 149.8% in cassava compared with galamsey soil control. This study showcases a circular economy-based approach that employs locally available resources to restore mining-degraded landscapes and enhance regenerative agricultural practices, reducing waste, bioaccumulation of heavy metals and improving carbon sequestration. Promoting the use of biochar and poultry manure amendments for ecological restoration in mining-degraded areas can contribute to sustainable land use, food security, and livelihoods. Policymakers should consider these strategies to align with global and national development goals while improving food systems and ecosystem services. Future research should explore the long-term impacts of cassava cultivation on amended mining sites and assess the potential of these amendments for agroecological enhancement and heavy metal immobilization.

This study aimed to identify fertilization options for improving cassava productivity and profitability in two contrasting regions of the Central African Republic. The Pissa (guinea forest) and Damara (savannah). The study adopted a randomized complete block design with four treatments replicated four times in a plot size of 7 m by 7 m. The treatments were; T1 (Control), T2 (Peasant practice), T3 (sole NPK), and T4 (Cow manure+NPK). We performed the analysis of variance (ANOVA) using R statistical software version 3.1.2. The yield attributes and growth parameters significantly varied (p=0.05) with application of NPK and NPK plus manure. The use of 3 t ha -1 of cow manure and 90N-30P-180 Kg ha -1 of mineral fertilizer gave the highest yield of 50 and 37 t ha -1 in Pissa and Damara respectively compared to their local controls (no input); This combination also resulted in high profitability with high value-tocost ratios (RVC = 2 in Pissa and 1.3 in Damara). The variability study (48.11%) showed a correlation between growth and production parameters; the effects of fertilizers were much more expressed in the plant's circumference and the number of leaves. The use of organo-mineral fertilizer can give good productivity and profitability. Thus, T4 is a technology that resource-poor households can easily use, although the purchasing power of the peasant farmers in the study area is low.
