ABSTRACT Organic farming, especially organic rice requires a continuing supply of organic fertilizer in large quantity as a source of nutrition for rice plants. In long-run, organic system is can retain higher soil organic carbon (SOC), partially compensates the negative impact by improving physical and biological properties, as well as nutrient retention capacity of the soil. Azolla pinnata is an organic nitrogen source rich in protein. The high nitrogen content in A. pinnata is related to the presence of nitrogen-fixing Anabaena azollae microsimbion in A. pinnata leaves. A. pinnata compost is an alternative for biofertilizer carrier that can be used in organic rice fields. The contribution of azolla-based organic farming for organic farmers is to decrease the dependency on the animal manure in cropping season. The field experiment comprised of conventional compost as control and combination of organic fertilizer and biofertilizer with Azolla carrier. Organic fertilizer were 5 ton/hectare (ton/ha), 7.5 ton/ha, and 10 ton/ha combined with 0, 10, 20 kg/ha biofertilizer with Azolla carrier with no addition of inorganic fertilizer. Complete randomized design were used in the experiment which consisted of three replications. This technology produced organic fertilizer better than conventional compost of rice straw and manure made by farmers. Organic fertilizer base with Azolla mixture of 7.5 ton ha-1 plus solid biofertilizer (10 kg/ha) can produce 6.58 ton/ha of dry harvested grain, higher than conventional compost treatment (control). The application of organic fertilizer base on azolla and solid biofertilizers gave the increasing yield prospect of organic rice in Cisayong, Tasikmalaya regency West Java.Keywords : Azolla pinata, carbon, nitrogen, organic farming, rice.

ABSTRACT Slope held a vital role in soil formation and development through erosion, transportation, and deposition. The degree of the slope determines the flow rate and volume of surface water, while the slope position determines rate of the erosion. The research aimed to understand the impact of the slope position against physical (texture, Bulk Density, top soil thickness,) and chemical (pH, Organic carbon, and cation exchange capacity (CEC)) and the correlation between the top soil thickness to physical and soil chemical properties. The research was conducted in April to June 2016. The soil samples were taken from 15-25% slope and three positions: upper slope, middle slope and lower slope. Each slope was repeated 5 times, hence 15 spots of soil samples were obtained. This research used descriptive comparative method and stratified purpose sampling as the sampling technique. The results of T-Student test showed that the slope position influenced the topsoil thickness of 6.91 point in the upper and middle slope and 3.89 point in the middle and lower slope. The results of the correlation test in each parameter in the upper hill showed there was correlation between top soil against dust fraction (r=0.826), top soil against clay fraction (r=0.823), and top soil against soil CEC (r=0.787). The middle slope showed there was correlation between top soil and soil pH (r=0.872) and topsoil to soil CEC (r=0.790). The lower slope showed there was correlation between top soil and soil pH (r=0.870).Key words: soil erosion, Inceptisols, slope position, topsoil

ABSTRACT Andisols developed from parent materials of volcanic eruptions. Volcanic eruptions can occur within several periods, resulting in a sequence of soil layers that can differ from each period and produced lithologic discontinuity in the soil profile. Lithologicac discontinuity was investigated in Andisols developed from the eruptions of Mt. Tangkuban Parahu (Holocene, andesitic) and Mt. Tilu (Pleistocene, basaltic) in West Java through morphological observations of three profiles at each location. The results showed that there was lithologic discontinuity in all profiles indicated by changed in color by Munsell Soil Colour Chart, organic carbon, texture and structure as the specific A buried horizon that developed from the parent material of the earlier eruption period than the horizons above. It is recommended to carry out the mineralogical and micromorphological analyses to determine the differences in minerals and micromorphology of the discontinue horizons and carbon-dating analysis in the buried layer to determine the age of the soil and the period of eruption that developed the soil.Keywords: A buried horizon, Munsell Soil Colour Chart, organic carbon, soil mineralogy, soil morphology
