Accumulation of organic matter in fragments of capoeiras.

Abstract

The work proposes to analyze the incorporation of biomass in the different models of management
in capoeiras and to investigate the influence of the management in the increment and
maintenance of the fertility. Five rows were used, T1-Farm traditional, T2-Farm enriched, T3-Alley
System, T4-Farm with vegetation strip, T5-Farm without fire. 25 litter samples were collected
from the 5 areas, with a 0.5m x 0.5m square, which was then dried and weighed. There was
variation of total dry matter sampled between the implantation areas, although with equal fallow
time, with T3 being the area with the highest volume. The mean values at T1=288.6g.0.25mē²
and T4=255g.0.25m were higher in T3=522.6g.0.25mē² and T5=297g.0.25mē² ~ 2 and,
T2=147g.0,25m~² the smallest values. The leaves are the largest constituents of biomass and
the second, the branches. This reflects its importance for the recovery and maintenance of soil
fertility in sustainable agroecosystems through the cycling of nutrients.
