Impact of Chemical Fertilizers on Diversity and Abundance of Soil-Litter Arthropod Communities in Coffee and Banana Plantations in Southern Rwanda

“…We conclude that the mode of feeding of Japygidae and Termitidae enhances the decomposition processes in soils which enriches the soil in nutrients (Grazia et al, 2015). On the other hand, even though Araneae are bioindicators of environment change (Maleque et al, 2009), while Coccinelidae are predators (Biranvand et al, 2018), nothing is known about the contribution of Salticidae, Pholcidae, Coccinelidae and Paederinae families to soil properties. Maybe they do it through predation on the prey that has an impact on soil properties, or their presence might be associated to other characteristics not measured by this study such as the vegetation types under coffee plantations treated with organic fertilizers and organic mulches or parts of coffee plantations.…”

“…In low and high elevation forests of Puerto Rico, the abundance of litter arthropods increased in the wet forest fertilized plots due to the accumulated litter from the vegetation (Yang et al, 2007). Another study conducted in a Texas pine plantation reported that arthropod species richness increased following nitrogen and phosphorus fertilization, even though Shannon diversity indices did not (Bird et al, 2000). Effects of chemical fertilizers on soil-litter arthropod diversity and abundance in different agroecosystems is still far from being understood, especially in agricultural lands in tropical regions.…”
