Abstract
The research was carried out in the Sumidero Silvicultural Unit, belonging to Empresa Agroforestal Minas, with the objective of evaluating the contribution of leaf litter to the soil in stands of Pinus tropicalis Morelet. The collection of leaf litter was carried out in two sites: stand 1 with site quality I, stand 4 with site quality II; rectangular traps-collectors (1X0.5 m) were placed in each stand, in plantations of P. tropicalis, with ages between 15 and 24 years. Soil samples were obtained with and without leaf litter, in which the contents of nutrients (phosphorus, potassium, magnesium, calcium) and organic matter were determined. The results showed significant differences between soils with and without leaf litter, more accentuated in phosphorus and organic matter, with increases higher than 4.9 % and 3.9 % as a consequence of the accumulation of leaf litter; whereas, the highest contribution of nutrients and organic matter is produced in the surface of the soil and decreases, appreciably in the soils extracted from the soil pits made in the stands, maintaining the differences between these in the contents of phosphorus and organic matter.

Claim · model-written summary
The highest contribution of nutrients and organic matter occurred at the soil surface and decreased appreciably in soils from the pits made in the stands.
