Udipsamment is characterized by sand fraction > 95%, loose, and very high leaching. This study aimed to determine the effect of mineral soil ameliorants and adhesive polymers on the character of nutrient leaching in Udipsamment. The leaching study in lysimeters used a completely randomized design with three replications. The treatments consist of bagasse (B), mineral soil included Inceptisol (I) and Vertisol (V), and adhesive polymers included tapioca 1% and 2% (T1 and T2), tapioca dregs 1% and 2 % (A1 and A2), Polyvinylalcohol 0.1% and 0.2% (P1 and P2). Combination of treatments are IB, VB, IBT1, IBT2, VBT1, VBT2, IBA1, IBA2, VBA1 , VBA2 , IBP1, I BP2, VBP1, and VBP2. Observations were made before and after leaching. The research showed that VBT2 increases moisture-holding capacity. Amelioration improved the ability of Udipsamment to hold nutrients, after leaching for six months, there was a decrease in organic C, total N, and available P compared to before leaching. Amelioration increased the soil CEC, even up to the sixth month leaching, the soil CEC showed a higher value than before leaching. The amount of clay fraction was relatively uniform between the surface and the bottom of the lysimeter, indicating that the adhesive polymer successfully bonding the clay-sand particles and prevented clay leaching.

Allophane is known as clay mineral with high capacity of phosphate adsorption via ligand-exchange mechanism. This study aims to compare the phosphate adsorption characteristics by allophane from Mt. Merapi and Mt. Lawu in relation to its chemical and mineralogical properties. The results of X-Ray Flourescence analysis shows that both allophane samples from Merapi and Lawu have low Si/Al ratio, i.e. 1.18 and 1.16, respectively. Infrared spectral characteristics of the allophane materials indicated that the main adsorption bands appeared at the range of 2700-3700 cm-1 (due to stretching vibration of all hydroxyl (OH) groups), 1400 – 1800 cm-1 (vibration of HOH deformation), and 650 - 1200 cm-1 (vibration between the Si-O-Al). Adsorption experiment of phosphate on allophane samples were conducted at initial adsorbate concentration of up to 2.0 mM and at pH 4.0 and 8.0. Phosphate adsorption capacity of allophane shows that both allophane from Merapi and Lawu are categorized as very high in adsorbing phosphate and fit well with the Langmuir adsorption equation. Phosphate adsorption increases with decreasing pH due to the positive charge sites such as Al-OH2+ in the allophane structure increase. Another reason is the negative charge of phosphate gradually decreases from -2 to -1 with decreasing pH, and the repulsive force between the negatively charged Si-O- in the allophane structure and phosphate anions decreases.

The pond bottom soil of Inceptisols mixed with Ultisols (I-U) and Vertisols (I-G) with the proportion of (70:30); (50:50); (30:70) showed the improvement of clay fractions >30% compared with the control (100% Inceptisols). These mixtures were given basal fertilizer (quail droppings manure with dosage of 2 tons/ha/month), Urea, and SP36. Cultivation system was divided into two stocked: fish ponds with 50 fish/m2 and ponds without fish. The best mix with the basal fertilizer was further treated with fertilization treatment (1 ton/ha/month of quail droppings manure) 3 times within 42 days of larval rearing. Physical and chemical soil analyses showed an increase of total soil porosity (> 50%), decrease of SG, BD, and permeability (medium), pH > 5, the CEC > 20 cmol (+) kg-1, and the C/N ratio < 6.5. The proportion of the best mix of 30% I : 70% U and 50% I : 50% G with 3 times of the fertilization frequency gave significant improvement of water quality, chlorophyll-a, diversity of plankton, benthic algae, fish growth, and total biomass. The presence of mineral montmorillonite on a mixture of 50% I : 50% G was a very good sign of the bottom soil fertility.

The kinetics of N release during the process of decomposition of organic matter is influenced by organic matter quality, temperature, humidity, and decomposer. Acacia, coffee, salacca, and bamboo leaf litter are native plants and be the pioneer plants on the slopes of Mount Merapi after the eruption in 2010. However, there is a lack of information on the N mineralization process from the leaves litter of acacia, coffee, salacca, and bamboo. The study aimed to determine the kinetics of N release from the litter leaves of acacia (Acacia decurrens), coffee, salacca, and bamboo, which were tested with three approaches, namely zero order, first order, and second order. The experiment was carried out using 10 Phretima californica earthworms that were incubated with 35g of annual plant leaves at 25°C. The levels of NH4+ and NO3- were measured at 0, 7, 15, 30, 45, 75, and 105 days after incubation by using the indophenol blue and derivative spectrophotometric method, respectively. Throughout the decomposition 105 days, the release of NO3- was higher than that of NH4+ due to the nature of NH4+ that was more easily immobilized than NO3-. The highest NO3- release in acacia litter (1.56 mg kg-1) occurred 30 days after incubation, while in coffee, salacca, and bamboo occurred 105 days after incubation, reaching 1.92 mg kg-1, 2.47 mg kg-1, and 1.88 mg kg-1, respectively. High N compound on the leaves litter unaffected to increasing total biomass earthworms in the end of incubation however promotes N mineralization rapidly. The kinetics of the second-order equation showed higher compatibility than the other equations to the N release with coefficient determination was higher. The kinetics of mineralization can be a strategy to use the leaves litter of perennial plants as sources of N nutrient input into soil.

Farmyard manure and azolla are potential sources of organic fertilizer in organic paddy field. This study aimed to determine the effect of using farmyard manure and azolla on growth and yield of rice crop. The research method was field trial in an organic paddy field, Sukorejo Village, Sragen, Indonesia. Experimental design which used was a completely randomized block design with 9 kinds of treatment which are repeated in 3 blocks. These kind of treatments were the using of farmyard manure, azolla fertilizer, azolla inoculum, and the combinations which is based on the fulfillment of nutrient requirements of 120 kg N ha-1. Farmyard manure significantly increased the fresh weight of biomass (two-way ANOVA F = 3.13 p < 0.05), the weight of grains per panicle (two-way ANOVA F = 3.36 p < 0.05) and dry grain harvest (two-way ANOVA F = 3.71 p < 0.05). Azolla fertilizer significantly increased the plant height (two-way ANOVA F = 2.93 p < 0.05). Meanwhile azolla inoculum did not give significant effect on all parameters (both growth and yield). Dry grain harvest has very significant correlation with plant height (0.68**); fresh weight of biomass (0.79**); weight of grains per panicle (0.61**); and grain weight of 1,000 seeds (0.48*). The result of F test and correlation analysis showed that farmyard manure significantly increases the dry grain harvest through its role on increasing the weight of fresh biomass and grain weight per panicle. Azolla fertilizer also significantly increased the dry grain harvest through its role on increasing the plant height. However, the effect of Azolla fertilizer to increase the dry grain harvest was weaker than farmyard manure.

The phosphate solubilizing bacteria (PSB) can release insoluble phosphate in soil by anorganik-P dissolution, organic-P mineralization, and blocking of soil adsorption site. The selection of effective PSB, therefore, is urgently required to study the effectiveness of PSB. The research was arranged to determine: 1) P-solubi-lization or P-mineralization, 2) physiology, and 3) PSB inoculant improvement. The research was arranged in complete random design, with PSB isolate as treatment. The variables were: soluble-P, mineralize-P, adsorption-P, pH, PSB population, phosphatase and phythase activity. The result showed that PSB isolate 1 = Pseudomonas trivialis, 5 = Pseudomonas putida, and 9 = Pseudomonas fluorescens, were the best in P solubilization or P mineralization. Solubilization efficiency of isolate were 1 = 291%, 5 = 280%, and 9 = 347%. Five days incubation (the end of log phase or early of stationary phase) was the best time to culture harvest for PSB inoculant formulate. Within twelve months age of culture, population stability of PSB inoculant decreased between 81 and 88%, and P solubilizing stability PSB inoculant decrease between 65 and 81%. Decreasing of P solubility to P source types of PSB inoculant was AlP > FeP > PR > CaP.

Kalibawang is one of the hilly areas in Kulonprogo Regency. Most of the people in this area are Muslim, although the number of followers of other religions is also growing. Part of the people in Kalibawang are converts, are a lower until middle class society. The existing economic limitations have made some of the converts formed a group of goat breeders with capital from donors. This goat breeder group has been running for about 1 year and has 6 members, with the number of goats increasing. The problem is the limited knowledge of the members of the farmer group for integrated goat farming system. The solutions offered are 1) providing training on the manufacture of organic fertilizer from existing goat farm waste; 2) integrated goat farming practices. The results of the assistance carried out, before the training was carried out, all converts did not know how to make organic fertilizer and cultivate goats correctly. After the counseling and mentoring was carried out, farmers began to understand the integrated goat farming technique, and began to put it into practice, both in waste management and in the design of healthier cattle pens.

[RESPONSE OF THE NUTRITION LEVELS OF SUGARCANE IN THREE ORDERS OF SOIL DUE TO SUGARCANE MONOCULTURE CULTIVATION]. Monoculture cultivation will have an influence not only on soil conditions but also on plant growth, nutrient levels in plant tissues, and yields. The purpose of this study was (1) to determine the effect of monoculture sugarcane cultivation on nutrient levels of the roots, stalks, and leaves of sugarcane plants, (2) to determine the relationship between nutrient levels in sugarcane tissue and sugarcane productivity, and yield in three different soil orders. This research had two factors, namely soil order (Entisol, Inceptisol, and Vertisol) and sugarcane monoculture period (1–10, 11–20, and 21–30 years). The sugar cane used was the ratoon of two sugarcane. Parameters observed included nutrient levels of N, P, K, B, and Zn in roots, stalks, and leaves of sugarcane, and productivity of plants. Data analysis was performed with ANOVA at 5% level and regression correlation analysis. The results showed that the levels of N (leaves, stalks, and roots), levels of P (leaves, stalks, and roots), levels of leaf K, levels of B (leaves and roots), and level of Zn of sugarcane roots were influenced by the interaction between soil order and sugarcane monoculture period. Zn and K levels in sugarcane leaves had a strong and significant correlation with sugarcane productivity (r=0.778* and r=0.699*), while sugarcane yields had a strong and significant correlation with N content of root (r=0.752*). This result indicates that the soil order and the mass of sugarcane monoculture have an effect on the nutrient content in the plant and this nutrient content affects the productivity and yield. The availability of macro and micronutrients needs to be considered in monoculture sugarcane planting techniques to obtain optimal and sustainable sugarcane yields.
