Monitoring populasi mikroba dan aktivitas enzim tanah lahan kacang tanah pada percobaan aplikasi pupuk organik hayati

In order to study the effect compost and plant growth promoting rhizobacteria (PGPR) on soil enzymatic activities of peanuts (Arachis hypogea) an experiment was conducted at Cibinong science center area 2011. Experiment laid out as factorial design with five replications. The treatment were 3 different composes (Filicium:F, grass: R and mixed ornament plant wastes:C) and 3 dosages of liquid organic bifertilizer (P1, P2 and P3). Results showed that treatments of Composes increased biochemical properties on Soil (resporation, enzymatic activities and population of benificial soil microorganisms). In general Felicium compos gave better results than other copmposes on improving biochemical properties. Higher concentration of liquid organic biofertilizer treatments did not always give better results on impruving soil biochemical properties. The correlation of biofertilizer with soil biochemical properties will be discussed more detail in this paper.
