Abstract

Study of Organic and Inorganic Acid Capabilities in Solubilize Phosphatic Rock‐P. Phosphatic rock has been used as phosphate fertilizer for along time and now being an alternative of P fertilizer. But its low solubility making them uneffective source of P for plant. Many attempt to increases their solubility has been done i.e. by acidulated it with organic and inorganic acid. Inorganic acid solubilize mineral P by acidification while organic acid by acidification and maybe chelating mechanism. The aim of this research is to study the effectivity of the two kind of acid, organic (citric acid) and inorganic acid (sulphuric acid) in solubilizing phosphatic rock‐P. Research has conducted in May – Oct 2007 at Soil Biology Laboratory, Gadjah Mada University, Yogyakarta. The experiment arranged in Completely Randomized Design with three level of sulphuric acid concentration (0.00 M, 0.02 M and 0.04 M), three level of citric acid concentration (0.00 M, 0.02 M and 0.04M) and three kind of phosphatic rock (Christmas Island, Ciamis and Madura) origin. Each of combination treatment replicated three times. A gram of each phosphatic rock was added to 50 ml of aquades in 150 ml erlenmeyer flask and shoke continuously at 200 rpm in reciprocal shaker. Water soluble‐P and pH were analysed at 0, 3, 6 and 9 day after incubation time. All data was analysed for anova at 95% level of significance and continued with DMRT if any significance differences. Research show that inorganic acid (sulphuric acid) solubilize phosphatic rock‐P stronger than organic acid, except for high content Al phosphatic rock, where the two kind of acid have equal P‐solubilizing capacity. Maybe, the high P‐solubilizing capacity of organic acid for high Al‐phosphatic rock caused by its ability in chelating Al. Keywords: Fosfat, batuan fosfat alam, asam sitrat, asam sulfat

Abstract

Title : The Inoculation of Sulfur Oxidizing Fungi on Phosphate Rocks Fertilizer  to Increase Their Available Phosphate and Sulfate. Phosphate rocks as an alternative sources of P fertilizer are cheaper than SP-36. The main problem was their low of total and available P that must be increased to make them more effective source of P for plants. Inoculate them with S oxidizing fungi will increase their available-P. The research aim was to study the potency of two S oxidizing fungi Aspergillus japonicus and Penicillium nalgiovensis to increase available-P of phosphate rocks. Experimental research done at the Lab. of Soil Biology and Lab. of Soil Chemistry and Fertility, Department of Soil Science, Faculty of Agriculture, UNS, Surakarta, at March – Mei 2008. The experiment arranged in completely randomized design with four factors i.e. the origin of elemental sulphur (from G. Welirang, East Java and from USA), the origin of phosphate rocks (Christmas Island, Ciamis and Madura), kind of inoculums fungi (A. japonicus and P. nalgiovensis) and inoculums densities (0; 106 and 107 spore/g of phosphate rock). Each treatment combinations were replicated three times. Fifty grams mixture of phosphate rocks, cassava solid waste, tapioca and rice bran was poured in 250 ml Erlenmeyer, sterilized with autoclave at 121 oC for 30 minutes, three times alternately in 5 days, then inoculated with fungus spores and incubated at field capacity in room temperature for 3 months. Samples were taken at 1, 2 and 3 months after incubation time for analysis of water soluble-P, soluble sulphate, pH and total fungus. Data analyzed statistically with F test and Duncan Multiple Range Test at 5% of level significance. The result show that the two of S oxidizing fungi Aspergillus japonicus and Penicillium nalgiovensis were be able to increases available-P of phosphate rocks, as well as soluble sulphate more than 200 % of control treatment. Penicillium nalgiovensis was more effective than Aspergillus japonicus. As P sources, phosphate rock from Christmas Island was better than from Ciamis and Madura, while elemental S imported from USA was better than local So from G. Welirang. The increase of inoculums densities and length of incubation times increase soluble P and sulphate. Keyword: phosphate rocks, S oxidizing fungi, soluble P and sulphate

Abstract

Shallot is a high-economic value commodit, but so far the supply is still lower than the demand. One of the production problem is “moler” disease of shallot (MDS) caused by Fusarium oxysporum f.sp. cepae (FOCe). The aim of this research was to study the potentiality of shallot rhizobacteria (SRB) from various soil ordo to inhibit (MDS). This research was held in the Laboratory of Biology and Soil Health and Greenhouse at UNS. This research was carried out by exploring rhizobacteria of shallot planted on Entisols, Andisols, and Vertisols. Rhizobacteria exploration results were tested for their ability to control Fusarium oxysporum f.sp.cepae (FOCe). Inhibitory ability test of SRB to FOCe was carried out in vitro and on shallot in the greenhouse. The research cused a Completely Randomized Design (CDR) with two factors. The first factor was rhizobacteria combination and the second factor was various soil ordo (Andisols, Entisols, and Vertisols). Each treatment was repeated three times. It was obtained three rhizobacteria isolates from Vertisols (B15: 70%), Andisols (B12:45,55%), and Entisols (B10:46,67%) being the highest inhibition results to FOCe. The combination of rhizobacteria B12 and B10 provided the lowest intensity.
