The use of inorganic fertilizers for a long term can reduce soil fertility. One of the alternatives solving this problem is by using solid biofertilizers. Solid biofertilizer requires carrier materials that can support the viability of potential microbial within. Azolla pinnata is one of the carriers that has potential as a substitute for commonly used carrier materials. This study aims to determine the effect of Azolla pinnata and other organic materials with inoculant dosage on viability of bacterial population, N-total, P-total of solid biofertilizer. This research was conducted at Soil Biology Laboratory, Department of Soil Science, Faculty of Agriculture, Padjadjaran University in January-February 2015. The treatments were organic matter (Azolla pinnata, litter compost and peat) with various dosages of bacterial inoculant (20%, 25% 30%). This experiment used the Completely Random Design with factorial pattern. The main observations of the study were analyzed by ANOVA test and continued with Duncan test with 5% confidence level. The results showed that Azolla pinnata carrier has significantly effect to the increase of N-Total and P total of solid biofertilizer. The inoculant dosage of 30% affects the population increase of Azotobacter sp., and endophytic bacteria, but does not effect to the population of Phosphate Solubilizing Bacteria and Azospirillum sp. Azolla pinnata can be recommended as an alternative carrier that can replace peat and litter compost materials.The results of this study was illustrate Azolla pinnata can be recommended as an alternative carrier for solid biofertilizer that can replace peat and litter compost material with 30% inoculant dosage.Keywords: Azolla pinnata compost, litter, peat, solid biofertilizer

Marginal soils have problems of low availability of nutrients, especially phosphorus. Phosphate solubilizing microbes can produce organic acid that dissolve P in the soil. Futhermore, the PSM also produce extracellular enzymes asa phosphatase that catalyze mineralization of organic P become inorganic P. Phosphate solubilizing bacteria (Pseudomonas mallei and Pseudomonas cepacea) and phosphate solubilizing fungi (Penicillium sp. and Aspergillus sp) is selected based on the ability of dissolving P and the production of growth regulators. Research at this stage aims to determine the biological fertilizer application techniques (PSB and PSF) as well as different types of P fertilizers to improve soil P available, growth and yield of maize. Field experiment on Ultisol Jatinangor implemented using a randomized block design (RBD) to test how applications PSM plus (giving 1, 2 and 3 applications) as well as the type of fertilizer P (SP-36 and rock phosphate). The results showed that the application of PSM can improve soil P-available growth and yield of maize. Application of PSM biological fertilizer could reduce the need for fertilizer P by 50%. PSM application once the application (early planting) with SP-36 dose 50% can increase content of soil P (P-available), and yield of maize on Ultisols.Keywords : maize, phosphate solubilizing microbes, Ultisols

Chromolaena odorata (L.) is a potential compost since it has high biomass and contains calcium, manganese, potassium and nitrogen. The aim of this research was to know the potency of siam weed Chromolaena odorata compost on soil chemical and chili plant performance. The experiment was arranged in factorial randomized block design consisted of two factors and three replications. The first factor was variety of fertilizer (no fertilizer, cow manure, siam weed compost and inorganic fertilizers) and the second one was the tanglefoot (with and without tanglefoot). Overall, the results of study showed that C. odorata compost could increased crop performance when compared with the other fertilizers in terms of number of fruits, fresh/dry weight of fruits, dry weight of crops, and N-total (leaf, stem, root and fruit), though there was no difference in fresh weight of crops among treatments. Furthermore, the effect of siam weed compost was not significantly different on soil chemical if compared with all treatments. This study is likely suggesting that C. odorata compost gives a positive effect to crops performance and soil chemicals.Keywords: Chili, Chromolaena odorata, compost fertilizer, tanglefoot
