Resumo
During two consecutive years, monthly macronutrients quantities transferred from the vegetation to the soil via fine litter were estimated in an area of mesophytic semideciduous forest located at municipality of Araras (42°23WG, 22°18'S) in the State of São Paulo, Brazil. The levels of macronutrients were much higher in the leaf litter than into twigs, flowers and fruits pointly analised fractions litter. For the litter leafs macronutrient quantities followed the order: N > Ca > K > Mg > S > P, while for the remaining fractions the order was Ca > N > K > S > Mg > P. The values for macronutrients in the leaves were significatively higher than the ones for the remaining fractions of litter (twigs, flowers and fruits). The macronutrient quantities (kg/ha) transferred year to year through the production of fine litter were: N = 230.0; Ca = 230.0; K = 79.0; Mg = 30.0; S = 27.0; P= 8.0.
