“…In addition to the effect of land use, management practices such as pesticide application can also greatly affect microbial communities and thereby nutrient turnover and speciation in agroforestry systems as revealed by Afolabi and Muoghalu (2018). These authors measured the influence of fungicide use on litter decomposition and associated microorganisms in cacao plantations in Nigeria.…”

In cocoa agroforestry systems, cycling of leaves, pods, and branches are key for organic matter sustenance. We investigated annual total litterfall, annual nutrient stocks in total litterfall, cocoa pods and beans, as well as cocoa leaf decomposition rates in cocoa agroforestry systems under conventional and organic management in Suhum Municipality, Eastern Region of Ghana. The study was conducted using six cocoa agroforests for each management selected from a total of four villages. Litterfall was collected monthly using litterboxes and a litterbag technique was employed to study the rates of leaf decomposition and nutrient release for 12 months. In June and July, total litterfall in organic farms were 94% and 65%, respectively, higher than in conventional farms, but management had no effect on average annual total litterfall of 8.8 t ha−1 yr−1 litterfall. Due to the trees’ reduced transpiration, 61% of the annual total litterfall occurred during the dry season. Whereas average leaf litter nitrogen (N) concentration was 17% higher in the rainy season than dry season, potassium (K) concentration was 38% higher during the dry season than rainy season. This likely reflected the contribution of N rich green leaves to litterfall in the rainy season and plant coping strategy to drought leading to K accumulation. Cocoa leaf decomposition was not affected by management. Annual potassium (K) and calcium (Ca) stocks in cocoa pod husk were four and nine-fold, respectively, higher than in cocoa beans. We conclude that organic versus conventional management had no effect on litterfall and cocoa leaf decomposition rather season influenced litterfall quantity and chemistry. Irrespective of management the spreading of cocoa pod husk after harvest will improve internal nutrient cycling in cocoa agroforestry systems.

Indonesia, as a country with a tropical climate, has a forest area of 94.1 million ha, and in 2019 deforestation reached 3,500,637.7 ha due to large-scale illegal logging for various activities. In addition, the area of primary forest has decreased over the last 15 years and is positively correlated with land degradation, carbon sequestration, and crop production. The low carbon sequestration capacity triggers global warming which has an impact on increasing the average temperature in Indonesia. Therefore, the restoration of forest functions to support ecosystem stability is the first step in forest management planning. The integration of trees and plants, namely agroforestry, is an option in the management of vegetation that is beneficial to the ecosystem. Tree-based farming systems have the capacity to absorb carbon dioxide from the atmosphere above ground, such as trunks, branches, and leaves, and below ground, namely the root system. Agroforestry has three main functions, namely regulating rainwater (soil and water conservation), sequestering carbon (reducing the impact of global warming), and supporting the microclimate (crop production). These three functions are supported by vegetation. Agroforestry systems provide options to reduce the effects of global warming, increase crop yields, and support ecosystem stability. Thus, a well-managed and sustainable agroforestry system is the best vegetation management that can solve the problem of deforestation.
