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

Inorganic fertilizer is a very important agricultural input to increase agricultural production. Uncalculated and continuous application of inorganic fertilizers will lead to the reduction of soil fertility and degradation of environmental quality. Therefore, a strategy is needed to support the environmental sustainability in agriculture. One of the efforts is through the production of biofertilizer and organic fertilizer from local resources. Organic fertilizer for rice plants can be made by utilizing the local water fern, Azolla pinnata. A. pinnata can be applied on rice fields as green manure by directly placing it into the soil or spread on the surface of rice fields. Organic fertilizer that made from Azolla will be more advantageous because it can be applied with biofertilizer. This study aimed to determine the formulation of Azolla based solid biofertilizer that can support the growth of functional microbial population based on the Agriculture Ministry (Permentan) standard number 70/2011. The design of the study method used was Completely Randomized Design with six replications. The treatments used were inoculant starter with 3% molasses, 3% molasses + 10% rice wash water, 3% molasses + 1% yeast extract, and 3% molasses + 10% rice wash water + 1% yeast extract. The results of this study showed that Azolla-based solids fertilizer with starter formula 3% inoculant molasses + 10% rice water + 1% yeast extract have the population of Azotobacter, Azospirillum, endophytic bacteria and phosphate solubilizing microbe were greater than 108 cfu/g dry weight. Functional microbial of solids fertilizers in all formulas used do not show the difference on inhabiting in the N-free media or Pikovskaya selective media. Keywords: Azolla pinnata, formulation, biofertilizer, organic fertilize
