The impact of Volcanic Ash of Kelud Eruption and Manure on Availability and Magnesium Uptake of Corn in Alfisols. Impact of fresh volcanic ash on soil fertility is rarely studied mainly on nutrient availability, uptake and on plant growth. Fresh volcanic ash is primary mineral that takes time and agents such as organic materials to mineralized before it contribute to soil fertility. This study aimed to study the effect of the thickness of fresh volcanic ash of Kelud Mountain and dosage of manure on availability and uptake of Magnesium and chlorophyll content of corn in Alfisol. This is greenhouse experiment arranged in factorial completely randomized design with two treatment. The first factor is the thickness of volcanic ash: 0, 2. 4, and 6 cm, and the second factor is the dosage of manure: 0, 2 and 4 tonha-1, each treatment combination was repeated 3 times. Variables observed include exchangable-Mg , Mg uptake, and chlorophyll content of corn. The results showed that there is no interaction effect of volcanic ash and manure on exchangable-Mg, Mg uptake and chlorophyll content of corn. This proved that they affect nutrient availability in different ways. Both volcanic ash of Kelud eruptionas as well as manure increase exchangable-Mg, especially at 6 cm thickness of volcanic ash treatment, Mg-uptake and chlorophyll content of corn leaf independently. There was a relationship between exchangable-Mg and chlorophyll content in the leaves.

The objective of the research was to study the effect of soil type and organic matters applied on the growth of innoculated Aspergilus flavus. Considering the caracleristics of soil and organic matter source types, the organic carbon content total nitrogen content. C/N ratio and pH of the soil were analized. The research design used was completely randomized block design with two factors, namely soil type (regosol, grucmosol and latosol) and organik matters applied (control; manure and straw). Treatment replication was considered as variation source of block. It was indicated that there was signcant effect (P < 0,05) of soil type on the growth of the fungsi. Latosol tended to give higher growth than regosol and grumosol. Though no significant effect of organics matters indicated, the fungsi showed better growth with application of straw. It seemed the result had nothing to do with the carbon and nitrogen content of the soil. They might be caused by other factors that should be studied further

Title : Study on The Potency of Soil Microbes Isolated from Andisols of Dieng, Central Java, as S-Oxidizing Biofertilizer Inoculant. The problem of nutrient deficiences tend to increase, including sulfur deficiency. The use of high purity NPK fertilizers stimulate sulfur deficiency in agricultural land. This problem can be corrected by the use of elemental sulfur accompanied with S-oxidizing biofertilizer. The study aimed to evaluate the potential of sulfur oxidizing microbial isolated from Andisols of Dieng Central Java as S-oxidizing inoculant. Andisols Dieng naturally contains high sulfur that allegedly inhabited many sulfur-oxidizing microbials. The research consisted of two experiments, each arranged in completely randomized design (CRD). Each experiment consist of two factors namely the kind of microbial isolated from Andisols Dieng and incubation time. The first experiment used Czapek-dox+elemental sulfur medium, while the second experiment used vermicompost as medium. The observed variables include soluble-S, bacterial density, biomass of fungi and medium pH. One isolate of bacteria (I1)and three isolates of fungi (F1, F2 and F3) taken from Andisol of Dieng showing their ability to oxidize sulfur in Czapek-dok agar medium. They were used as isolates in the experiment. The result of the first experiment showed that the oxidized sulfur increased with the length of incubation time as indicated by the increase of soluble-S, bacterial cell density or fungi biomass in the medium followed by the decrease of pH. The second experiment showed that the population of bacteria or fungi isolates and soluble-S of vermicompost were increased collaterally with incubation time. The fungi isolate of F2 have the highest potency as inoculant of S-oxidizing biofertilizer as shown by it ability to survive, grows and oxidize S both in Czapek-dox+elemental sulfur liquid medium as well as in vermicompost medium.

Title : The Effect of Manure on Available-P of Phosphate Rock Fertilizer Inoculated with P-solubilizer Bacteria. Experiment conducted at Soil Biology Laboratory, Faculty of Agriculture UNS Surakarta. This experiment aimed to study the effect of manure on solubilising capacity of P-solubilizer bacteria on phosphate rock fertilizer. The experiment arranged in completely randomized design with two factors i.e. dosages of manure added and inoculums rates of P-solubilizer bacteria (PSB) (Bacillus megatherium var phosphaticum). The manure added were 0 g (K0), 250 g (K1), and 500 g (K2) per 5 kg phosphate rock fertilizer. While the PSB inoculums rates were 0 cell/g (B0), 5.105 cell/g (B1) and 10.105 cell/g of phosphate rock fertilizer. The variables analysed at 2, 4 and 6 weeks after incubation for available-P, pH, organic matter content and total PSB. Data analysed with F test and DMRT at 95 % level of significant. The result indicated that available-P of phosphate rock fertilizer was significantly affected by PSB inoculation rates, doses of manure and incubation time. Available-P increase coincided with increasing of PSB inoculums and manure rates as well as incubation time. Treatment combination of PSB at 10.105 cell/g and manure of 500 g/ 5 kg increase available-P up to 80.59 ppm (151.5 % of the control treatment) at the end incubation time. Keywords: Manure, Phosphate Rock Fertilizer, P-solubilizer Bacteria
