Abstract

Ultisol is one type of soil that has a problem soil acidity, organic matter and macro nutrients is low and has a very low P availability. Businesses that can be done to improve the quality Ultisol by implementing the use of fertilizer P with one ingredient soil (humic acid). The research aims to study the effect of humic acid applications, fertilization P, and the interaction between the population and the diversity of soil mesofauna. This study was conducted in December 2018 until April 2019 at the Experimental Station of Agricultural Technology Assessment Agency (BPTP) Natar, using a randomized block design arranged as factorial with two treatment factors. The first factor is the application of humic acid which is divided into 3 dose level without application of humic acid (H0), 15 kg ha-1 humic acid(H1) And 30 kg ha-1 humic acid (H2). The second factor is fertilizer P were divided into 4 levels ie without TSP fertilizer dose (P0), TSP 100 kg ha-1(P1), TSP 200 kg ha-1(P2) And 300 kg ha-1 TSP fertilizer(P3). Data was tested with Bartlett’s test of homogeneity manifold and aditifitas data is tested by Tukey’s test. The next test Least Significant Difference (LSD) at 5% level. The relationship between C-organic soil, soil pH, soil moisture, soil temperature and soil mesofauna were tested with correlation. The results showed that the application of humic acid and fertilizer P is able to affect the population and diversity mesofauna land, and there is interaction between the application of humic acid and P fertilization on population and diversity soil mesofauna. Only there is a correlation between soil pH and soil temperature with the population and diversity of soil mesofauna.
