The aims of the experiment were to evaluate the effect of rock phosphate application and combination betweenphosphate-solubilizing bacteria with farm yard manure on nutrient uptake and yield of soybean. Factorial experiment design with two factors was used in randomized complzte block design with three replications. The first factors was level of rockphosphate i.e. : 0; 30; 60; 90 kg P ha· I, and the second factor was combination of phosphate solubili=ing bacteria andfarm yard manure: without phosphate solubi/i=ing bacteria andfarm yard manure; phosphate solubilbing bacteria (Pseudomonas fluorescens); farm yard manure 10 ton ha"I, and phosphate solubilizing bacteria + farm yard manure. The results indicated that rock phosphate and combination of phosphate solubilizing bacteria andfarm yard manure application increased nutrient (N, p, K) uptake and grain yield of soybean. Optimum dosage of rock phosphate in soil without phosphate-solubilizing bacteria andfarm yard manure (control) was 72.15 kg P hdl which gave maximum yield of soybean was 7.73 g pori. While with phosphate-solubilizing bacteria. farm yard manure and phosphate solubilizing bacteria+farm yard manure obtained optimum dosage of rock phosphate were 62.26, 63.94, and 62. 21 kg P hd1 , respectively, which gave maximum yield of soybean were 8.17, 7.95, and 8.43 g pori, respectively.

A proper management of crop residue can increase crop production since it plays an important role on increasingwater availability. The effect of crop residue application on soil productivity depends on many factors. In this research. theeffect of placement of crop residue and irrigation on soil physical properties and crop production were examined under field condition on dry season. The result showed that crop residue placement had no significant effect on all parameters of measured soil physical properties both under dry condition (no irrigation) and wet condition (with irrigation). The effects ofcrop residue placements on maize growth were also not significant. Nevertheless there was a tendency that surface application produced higher biomass than buried application. On grain yield, however. the effect of crop residue placement was significant. especially under dry condition with no water applied Surface application of crop residues produced higher grain yield than buried application.

Several experiments containing 2 field, 2 pot and I rhizotron were conducted to develop a low input agricultural practice(pelleting seed) for production of soybean plant (cv. Tidar) on heavily acid soils of Sitiung, West Sumatra. The field and polexperiments were conducted in Sitiung and in the greenhouse at the Agriculture Division, Center for the Application ofIsotopes and Radiation Technology, National Nuclear Energy Agency, Jakarta, respectively, in 1990 - 1992. The rhizotronexperiment was conducted in 1994 at the Laboratory of Microbiology, Department of Agrotechnology and Food Sciences.Wageningen University. Wageningen, The Netherlands. Lime-pel/eting seeds with the equivalent of 50 kg lime ha·1 increased nodulation, growth and yield both in unlimed and limed soils. Considerable increases in nodulatio, growth and yield were obtained when a small amount of P fertiliser (J 0 kg TSP ha·l ) was incorporated in the lime-pellet. The beneficial effects of both lime-pelleting and [lime+TSPj-pelleting were more pronounced on nodulation than on growth and yield. and greater in umimed soils than in limed soils. Large effects were obtained in nodulation, growth and yield of soybean in field experi1ltl!nts by pelleting seeds with lime or with lime + TSP. However, the pel/eted soybean plants grown in unlimed soils remained small and yields were negligible. To sustain growth and production of soybean in these acid soils, adequate quantities of lime and of P fertiliser would be necessary. In the present study, a combination of broadcast lime at 2.0 t ha-I with [lime+TSPj-pelleting of inoculated seeds was found superior to the application of 7.0 t ha-I of lime with inoculated seeds only. A I toxicity and P deficiency were the main problems in these acid soils. For the low-input production of soybeans considerations shOllld be directed to the correction of these factors.

For supporting better soil management, the spatial distribution of soils having argilic hori=on (argilic soils) must berecognized and it can be delineate in soil survey mapping activity, but this activity consumes much time and money. This study aimed to build a decision tree model for predicting the spatial distribution of argillic hori=on based on auxiliary information using 3 predicting environmental variables; namely, geomorphic sUrface or substrate, landsurjace unit, and ecoregion beh.Three-based modeling technique was used to generate classification tree model from 318 pedon of Lampung Province,Indonesia. Argillic horizon is predicted to present in hot belt (elevation of 0-200 m above sea level) on interfluve-seepageslope with probability 84% for acid igneous rock, 83% for basic igneous rock, and 90% for acid sedimentary rock. Argillichorizon is also predicted to present in hot belt on transportational midslope with the probability 65% for transported acid sedimentary rock. Argillic horizon is predicted absent with the probability to occur ranging from 0% to 32% on otlrer combinations of landsurface unit, ecoregion belt, and substrate.

The study is intended to examine the survival of Aspergillus niger and its phosphate solubilizing ability when pelletedwith rock phosphate. An A. niger YD 17 obtainedfrom the Laboratory of Microbiology. Faculty of Agriculture, Gadjah MadaUniversity was used. The pellet was made by mixing rock phosphate (80%) with organic matter (J 3. 9% waste of tapioca. 6% rice bran, and 1% starch) and spore of A. niger. The experimental design was the Complete Randomized Design 5x4 with 3 replicatiOns. The first factor was sources of rock phosphate (Christmas Island. Jordan, China, Ciamis, and Madura). The secondfactor was the number ofinoculums i.e. control without inoculums, 107 • J(t and J(t cfu.g·'. The colony of A. niger that formed at medium of potatoes dextrose agar (PDA) and the amount of soluble phosphorus in the Pikovskaya liquid medium were parameters. Experimental results indicated that sources of rock phosphate and the number of inoculums itif1uence the A. niger survivability and its phosphorus solubilizing ability. Rock phosphate from Ciamis gave the best support for fungus survival and rock phosphate from Christmas Island was the best substrate for phosphate solubilization. The highest soluble phosphate was achieved by ul inoculums.

Aggregate stability is one of the important factors to be taken into account in controlling soil degradation. It influences soil ability to resist soil erosion. Therefore, it is necessary to have accurate measurement of aggregate stability that able to express well its resistance to dispersion. In this study, aggregate stability of various soil types were measured using different wet sieving time and aggregate size. Latosol Sindangbarang showed the highest aggregate stability index (ASI), followed by Podsolik Jasinga, Andosol Sukamantri, Lalosol Darmaga, and Regosol Sindangbarang Wei sieving time significantly affected AS!. The ASI decreased as wet sieving time increased The result also showed that different methods result in significantly different stability index. The method that used smaller size aggregates (< 2.83 mm) results in about 3 to 4 times higher stability index.
