ABSTRACT
Changes in soil quality of sugarcane plantation as a result of changes
in land management can not be measured directly, but must be demonstrated by
measuring the change in the properties of the ecosystem as an indicator. This
research aimed to study the effect of the addition of various quality and
quantity of organic matter on soil biology (earthworms) and physical
quality (aggregate stability, macroporosity and infiltration rate). There were
15 treatment combinations tested. The first factor is the type of organic
matter: (1) cattle manure (CM), (2) filter cake
(FC), (3) sugarcane trash (ST), (4) a mixture of CM + FC and (5) a mixture
of CM + ST. The second factor
is the application dose of organic
matter, which consists of
three levels—5, 10 and 15 Mg/ha. The treatments were arranged in a factorial randomized block design
with three replicates and one control treatment (without organic matter input).
The result of this research showed that the highest population density of
earthworms was found in the treatment of ST (78 individuals/m2) and a mixture of CM + ST (84 individuals/m2). The
type of organic matter with C/N ratio ranged from 15.5 to 34.7 and cellulose content in 33.3%-40.1% gave better
growth of earthworm. The effect of increase in earthworm growth on soil
physical improvement is more apparent in the
treatment of mixture of low quality and high quality organic matter. The
increase of earthworm density and biomass enhanced soil macroporosity (from r = 0.683 to r = 0.606) and
infiltration rate (from r = 0.669 to r = 0.756). The results
of this study suggest a mixture of CM + ST or ST alone as organic matters, which is recommended
to improve soil physical and biological quality of sugarcane land, with the dose
application ranged from 10 Mg/ha to 15 Mg/ha.
