Abstract
This research aims to determine the effect of leaching on soil characteristics, water quality, and the benefit of inorganic fertilizer and local organic matter to support a new established filed of rice growth on actual sulfuric acid soil. The research began with composting in the Belandean experimental field, pot experiments in greenhouse and soil, water and plant analysis in laboratory of Balittra, Banjarbaru, Kalimantan Selatan from February to May 2019. Randomized complete design was set on experimental field with two factors and three replications. The first factor is leaching by system, there are (1) DO = unreturned leaching water and (2) D1 = returned leaching water. The second factor is fertilization, there are (1) P0 = no additional fertilizer, (2) P1 = 50% of recommended NPK fertilizers, (3) P2 = 50% of recommended NPK fertilizers + Compost, (4) P3 = 100% of recommended NPK fertilizers + amount of compost nutrient which is substituted by inorganic fertilizer, and (5) P4 = 100% recommended NPK fertilizers. The results showed that by unreturned leaching water had the value of Eh, EC and soil Fe and SO4 content lower than other treatments. However, the lowest Al-dd and H-dd values were found in the treatment of returning water from washing and fertilizing NPK 50% recommended dosage by adding compost to inorganic organic matter. This treatment also has the highest biomass production value when compared to other treatments.

Abstract
ABSTRACT The Heap of sugar palm solid waste often become pollutants, potentially used as organic fertilizer by making it compost, because it contains organic matter and high N. Regosol is soil that has poor physical and chemical soil conditions for corn growth because it is constrained by a rough texture and low N. This study aims to determine the effect of compost from sugar palm solid waste on the availability of N Regosol and its uptake by corn. This research is a pot experiment, using Complete Random Design method (CRD) with 5 treatments, each treatment was repeated 3 times. The five treatments are: K0 = Compost at a rate of 0 tons / ha (control), K1 = Compost at a rate of 22.24 tons / ha, K2 = Compost at a rate of 44.48 tons / ha, K3 = Compost at a rate of 66.72 tons / ha and K4 = compost at a rate of 88.96 tons / ha. The results of the study were analyzed with variance at a 5% significance level if there is a real effect further tested by Duncans Multiple Range Test at 5%. The results showed that the application of palm sugar solid waste compost could increase the availability of N Regosol and N sweet corn nutrient uptake. Application of palm sugar solid waste compost at a rate equivalent to 44.48 tons/ha significantly responds to the increased availability of N Regosol and the best absorption of corn.

Abstract
ABSTRACT In many cases the yield and quality of organic rice farming system are better than semi organic and conventional rice farming systems; so many farmers want to move to organic rice farming system. The aim of the study was to know the soil fertilities and yield of rice biomass under organic system. The study was conducted in organic rice farming system in Termas Village, Sambung Macan Sub District, Sragen District from March 2019 to the end of June 2019. Soil composites were sampled in March 2019 at organic rice farming system. Composite soil samples were collected from ten sampling points and mixed. These samples were submitted to the Analytical Laboratory of the Jogyakarta Assessment Institute for Agricultural Technology for analyses of soil fertilities properties of the soils. The results indicated that in general the soil fertility taken in 2019 under organic rice farming was better including pH, C-organic, N total, P and K extracted with HCl 25 %. The same result was happened in rice biomass production namely rice grains yield (12.68 tons ha-1), rice straws (7.25 tons ha-1) and rice residues (4.15 tons ha-1).

Abstract
Monggol Village, Saptosari Subdistrict, Gunungkidul Regency is an area that often experiences drought, especially during the dry season, resulting in a lack of clean water for daily needs and for agricultural cultivation. The purpose of this study was to determine the quality of the soil on the plots of land that use PAM (Water Supply Company) water irrigation intensively to realize a food independent village in Monggol Village, Saptosari District, Gunungkidul Regency, Yogyakarta. This research was conducted using descriptive survey methods. Purposive soil sampling, taken at two locations. Location A: land without PAM water irrigation, planted during the rainy season, Location B: land with PAM water irrigation intensively, each location is taken 3 soil samples as replications. Soil quality is determined by calculating the Soil Quality Index using the criteria of Mausbach and Seybold (1998). Soil properties observed were soil texture, volume weight, specific gravity, porosity, actual pH, C-Organic, total N, available P, available K, root depth, and number of microbes. The results showed that the Soil Quality Index on land without PAM water irrigation (Location A) were: location A1 0.58; location A2 0.54; A3 location was 0.73 with an average of 0.62 including good soil quality criteria while the Soil Quality Index on land with PAM water irrigation (location B): location B1 is 0.39; B2 location 0.36; B3 location 0.30 with an average of 0.35 including poor soil quality criteria. Intensive tillage on land with PAM water irrigation causes soil quality to decrease or lower than rainfed land, this indicates the need for the addition of balanced fertilizer on intensively managed land.

Abstract
This study aims to determine the physical and chemical quality of oil palm midrib compost with the addition of ruminant rumen bioactivators (cattle, goats and buffalo). The material used in this research is palm oil fronds and ruminant animal rumen obtained at Gandus Abattoir in South Sumatra. This study uses a Completely Randomized Design with 5 treatments with 4 replications consisting of P0 (palm frond compost without adding bioactivators), P1 (palm frond compost with bio4 activator EM4), P2 (palm frond compost with bio rumen liquid bioactivator), P3 (Compost of oil palm fronds with buffalo rumen liquid bioactivator), and P4 (Compost of oil palm fronds with goat rumen fluid bioactivator). The parameters measured in the study are physical quality (odor, texture, pH, temperature and color) and chemical quality (nitrogen, water content, phosphorus, calcium and C-organic). The data obtained were analyzed by ANOVA, if there were real differences followed by Duncans test. the results show that the compost of oil palm fronds using rumen bioactivators from buffalo (P4) has better quality compared to EM4 bioactivators (P1) or bioactivators from goat (P2or cow rumen (P3).

Abstract
Bone is a by-product that causes bone heaps. Chicken bone contains 24-30% of Ca and 12-15% of P, so it can be used as a source of P and Ca, but not yet available. To dissolve it needs the addition of organic matter. Latosol is a soil that lacks of P and Ca. This study aims to determine the effect of application of flour from chicken bone waste and organic matters on the availability of P and Ca of Latosol and growth of corn. The study was carried out in the greenhouse of UPN “Veteran” Yogyakarta Faculty of Agriculture, on January to April 2019. The study used a completely randomized design of two factors. The first factor is the dose of chicken bone flour, are without chicken bone flour (A0), chicken bone flour 2% (A1), 4% (A2), and 6% (A3). The second factors is organic matters, are without organic matter (B0), compost 3% by weight of the soil (B1), and manure 3% by weight of the soil (B2). Each treatment was replicated 3 times. Application of chicken bone flour had a significant effect in increasing pH H2O, C-Organic, available-P, and available-Ca, plant height and plant dry weight. Application of organic matter had a significant effect in increasing pH H2O, C-Organic, available-P, available-Ca, plant height and plant dry weight. The combination of chicken bone flour and organic matters interacted each other in increasing available-Ca, while there are no interaction to affect pH H2O, C-Organic, available-P, plant height and plant dry weight.

Abstract
Limestone post mining soil had high levels of calcium carbonate and pH, this condition causing a lack of soil P availability, so the application of mycorrhizae and organic matter is necessary. This study aims to determine the effect of mycorrhizae and organic matter, and the best combination of mycorrhizae and organic matter on soil P availability of limestone post mining and growth of maize. This study was conducted at Greenhouse in Taman Teknologi Pertanian Lebaksiu, from February to May 2019. This study used a Completely Randomized Design two factors. The first factor was the dose of mycorrhizae, namely without mycorrhizae (M0), mycorrhizae 10 g / pot (M1), and mycorrhizae 20 g pot (M2). The second factor was organic matter, namely without organic matter (B0), cow manure 20 tons / ha (B1), corn litter 20 tons / ha (B2), and legumes liter 20 tons / ha (B3). Each treatment was repeated 3 times. The result shows that the aplication of mycorrhizae had a significant effect on the increasing C-organic soil, Cation Excange Capacity (CEC), plant height and plant dry weight, but it did not significantly affect on P-available, Ca and Mg. The application of various types of organic matter had a significant effect on the increasing P-available, C-Organic soil, CEC, plant height, and plant dry weight, and decreasing soil pH (H2O) and Ca, but it did not significantly affect on Mg. There was an interaction between mycorrhizae doses and organic matters on the increasing plant dry weight of 6 WAP.
