Phosphate mineralization and immobilization in slash and mulch
system in south-east Sulawesi, Indonesia
Many decomposition studies have been conducted to find out practical method in
utilization of organic nutrient. However the information about utilization of tropical
secondary forest vegetation in slash and mulch system as a stock of organic
phosphate and the mechanisms of P mineralization and immobilization in soil is still
limited.
Since the information about the advantage of the used of secondary
vegetation in a such system is still scarce, there is no reason for the farmer to applied
the mulching system derived from tropical secondary vegetation to their land for
sustaining the availability of P.
This study is conducted in laboratory scale, growth chamber, green house, and in
the natural condition in south-east Sulawesi, Indonesia. The experiments involved a
different quantity and quality of mulched secondary vegetation, addition of different
level of soluble phosphate fertilization to compensate the immobilized P after Prelease from organic pool, test plant grown on different growing media (with and
without mulching) to evaluate the effect of organic material amendment into the soil
on the P-dynamics and biomass production in green house, growth chamber and in
the natural condition.
The results of this study tries to contribute not only to provide information about the
rate of decomposition, the mechanism of P mineralization and immobilization in the
soil amended with tropical secondary vegetation but also the information about the
effect of use of slashed-mulched secondary vegetation on crops productivities.
The main objectives of this study are to asses the contribution of secondary
vegetation residue amended into soil on the improvement of soil available P, and to
identify the effect of amended secondary vegetation residue on crops production
and P uptake.
