ABSTRACT
The goal of this study
is to evaluate the drift of litterfall from forest to adjacent areas, validate
a method to estimate the drift with water balance, direction and speed of winds
and quantify the nutrients of litterfall in nearby area of the forest patch as
function of distance. This phenomenon can be considered an ecosystem service to improve soil
quality of the agriculture crops around the forests by nutrient input coming
from the litterfall. The experiment was installed in adjacent areas of the
tropical forest at central region of the State of Minas Gerais, Brazil. The
branches, reproductive material and leaves which fell were measured for three
years into the forest and adjacents areas. The sampled nets were located on
edge and equal distances from the edge. It’s analyzed and estimated the
contribution of the litterfall components to adjacent areas by air. The
quantity of litterfall by distance had large variation between adjacent areas.
And it was confirmed that model estimated the leaf drift by distance with good
precision.
