The addition of grinded pruning rests can improve soil quality but their mineralization depends on the type of rests, among other characteristics. The aim of this study is to analyse the evolution of nutrients over time in prun- ing rests from mango (MM), cherimoya (CC), avocado (AA) and gardens under mango (JM), cherimoya (JC) and avocado (JA) that were added to cultivated soils in an experimental area of the coast of Almuñécar (Granada, SE Spain). The avocado rests are the ones that show lowest nutrient concentrations and a higher C/N ratio, suggest- ing that they would have a slower mineralization rate. On the contrary, the garden rests have the lowest C/N ratio and highest contents of N and P. The cherimoya and mango rests have a higher relative concentration of K. After two years in contact with the soil, the initialN content increased in the avocado and mango rests, hardly increased in the cherimoya rests and did not change in the garden rests. The initial concentrations of K and P decreased in all type of rests
