Analysis of the efficiency of Prunus africana-based agrosystems

AbstractAgrosystems combining Cinchona ledgeriana with plant cover based on Prunus africana, Maesopsis eminii and other agroforestry species suffer from a lack of convincing scientific arguments for their evaluation. Among the questions still unanswered is that of the efficiency of the improvement in soil physicochemical properties, in particular changes in fertility and soil organic carbon storage.Investigations were carried out on four types of agrosystems on the Pharmakina agroforestry farm at Kagheri in the Lubero region, in order to assess the contribution of agrosystems to improving the fertility of sandy loam soils, sequestering soil organic carbon and improving the yield of Cinchona ledgeriana in the Lubero region.Soil samples were taken from the top 30 cm of the soil for granulometry and physicochemical parameters. Observations were made on dendrometric parameters (thickness and circumference).
