Abstract

This study investigates nutrients stock and some soil indices of agroecosystem soil as affected by monoculture cropping system (cacao plantation). This was with a view to provide comprehensive understanding of soil nutrient dynamics in the ecosystems due to their different management practices. The study was carried out in 0.063 ha sample plots, three each in natural forests and cacao plantations adjacent to each other. In each plot, Five core soil samples were randomly collected at two depths (0-15, and 15-30 cm) from each plot, bulked according to depth, air-dried, sieved through 2 mm-sieve and analyzed for soil physicochemical properties using standard methods. One-way ANOVA was used to determined significant difference among the measured parameters using SAS version 9.2. One-way analysis of variance was used to test significant mean differences of the nutrient stocks among agroecosystems. The results showed the soil physical properties such as particle size distribution, moisture contents and bulk density; chemical properties such as pH, exchangeable cation, organic carbon, organic matter, phosphorus and sulphur from forest ecosystem were higher than the soil properties in agroecosystem (cacao plantation) for both top and subsoil. Soil indices such as Soil structural stability index , Base saturation percentage and Sodium adsorption ratio were higher in forest ecosystem than the soil indices of   agroecosystem (cacao plantation). Therefore, long-term monoculture cropping system had significant effect on nutrients stock and soil indices.
