SIFAT BIOLOGI TANAH MINERAL MASAM DYSTRUDEPTS DI AREAL PIRINGAN KELAPA SAWIT YANG DIAPLIKASI MULSA ORGANIK Mucuna Bracteata DI LAHAN PERCOBAAN FAKULTAS PERTANIAN, UNIVERSITAS RIAU
Abstract: The objectives of
this research to determine the soil biological properties on the acidic mineral
soil Dystrudepts in the area of disc palm oil applied of organic mulch Mucuna
bracteata in the experimental garden of Agriculture Faculty, Riau University.
Analysis of the soil biological was conducted in the Soil Laboratory of
Agriculture Faculty, Riau University, in October 2014 to February 2015.
Application of mulch organic M. bracteata used purposive random sampling method
which consisting of 4 levels and 4 replications. The levels is M0 (0 kg
/plant), M1 (15 kg /plant), M2 (30 kg /plant) and M3 (45 kg /plant). Parameter
observed : calculate the amount of soil biota macrofauna, mesofauna and
microorganism. Data were analyzed deskriptively statistically. The research
showed application of organic mulch M. bracteata 45 kg/plant increased the
amount of soil biota macrofauna, mesofauna and microorganism soil, in the area
of disc palm oil.
