Exploring theNutrient Release Potentialof Organic MaterialsasIntegrated SoilFertility Management Components Using SAFERNAC

The aim of this study was to establish the nutrient release potential of different organic materials and assess thei r role in integrated soil fertility management for coffee using the new coffee yield model SAFERNAC. It involved an incubation experiment conducted at TaCRI Lyamungu Screenhouse for 180 days between April and September 2011. Cattle manure, coffee leaves, p ulp and husks,Albizzialeaves and four green manure plants � Mucuna pruriens,Lupinus albus,Canavaliaensiformisand Crotalaria ochroleucawere
