    Abstract

    Zero Point of Charge (ZPC) is an important variable in describing the mechanism of reversible surface charge primarily on weathered soil dominated by variable charge. The presence of organic matter effect on the nature of the charge in the soil. Research goals include: 1). Obtaining information kinds of organic matter with a low pho, 2) Knowing the behavior of pHo and net charge in the ground, 3) Knowing the influence of pHo on the soil cation exchange capacity and 4) Knowing the influence of a variety of organic fertilizer on peanut yield.This study is an experimental functional relationship variables approach through experiments. The experiments were conducted at Greenhouse, the basic design used was completely randomized design of a single factor, namely: each treatment is repeated 3 times. The treatment is done as follows: P0 = soil without the addition of organic fertilizers, P1 = soil with the addition of cow manure 5 tons / ha, P2 = soil with the addition of chicken manure 5 tons / ha, P3 = soil with the addition of five quail manure tonnes / ha, P4 = soil with the addition of goat manure 5 tons / ha, P5 = soil with the addition of bokashi 5 tons / ha, P6 = soil with the addition of rice straw compost 5 tons / ha, P7 = soil by adding compost hyacinth 5 ton / ha. P8 = soil by adding compost Titonia 5 tons / ha and each treatment was repeated 3 times. Analysis of the quality of organic fertilizers include: levels of lignin and polyphenols, C/N, pH , pHo, humic acid and fulvic acid. The soil analysis includes the C-organic soil, total N, C / N, pH , pHo, CEC, The results showed that the zero point ofcharge (pHo) is the lowest organic fertilizer chicken manure (4.52). Obtained a close relationship between the difference in pH H2O with pHo with cation exchange capacity. Highest cation exchange capacity achieved in the treatment of chicken manure. Keywords: zero point of charge, pHo, CEC, organic fertilizer
