Abstract

The efficiency of fertilizer use is changing greatly depending on soil properties, fertilizer type, irrigation and level of intensive cultivation. A site specific potassium (K) experiment was conducted to formulate the fertilizer recommendation of K for rice plant in different K soil status. The objective of this research were to select a proper soil test method, classify the soil test value of K into two or more classes and fertilizer recommendation of K to rice plant. The result showed that the method of NH4OAc 1 N pH 7 was the best technique for soil analysis. Based on the method, there are 3 available classes of K i.e. low, medium and high. The soil with the highest availability of K does not require fertilizing with K, because it has been fulfilled by the water irrigation and straw. The fertilizer recommendation of K for rice plant at medium class is less than low class.

Abstract

This study aims to identify and provide land suitability database of Subak to support sustainable agricultural development and provide spatial information such as land suitability maps with existing inhibiting factor. The method used was field survey to obtain data characteristics/quality of land through soil sampling on several land units sample, and soil analysis in the laboratory. Land suitability classification was done using the criteria from the Technical Instructions Evaluation of Land for Agricultural Commodities by matching between the quality/characteristics of the land with the growing requirements of rice crop being evaluated. The analysis of actual land suitability both of S2 (little suitable) with limiting factors included drainage, texture, depth of planting, salinity, N- available, P-available and K-available, and slope; and S3 (marginally suitable) with limiting factors such as N-available, P-available and salinity. The assumption of business improvements that can be made to the determine quality/characteristics of the land Subak was an inhibiting factor, with optimization by improved drainage channels, N and P in accordance with the needs of the rice plant. Therefore the suitability of potential land for irrigated rice crops can be mapped by GIS and can be increased to very suitable (S1) level. In conclusions, the actual land suitability was categories as 72% little suitable (S2) and 28% marginally suitable or S3 with inhibiting factors included rooting medium, availability of nutrients, slope and salinity. While the suitability of potential land consisted of all of Subak that invery suitable (S1)level, so that the existence of Subak in Denpasar should be protected.

Abstract

Phosphatase in the soil was found as extracellular enzymes produced by soil micro-organisms both in acidic or alkaline conditions. Phosphatase is an enzyme complex that plays an important role in deciding soil-bound phosphate bond organic compounds to form orthophosphate which is available to the plant. Mineralization of organic forms into a inorganic-P determined by the ability of these bacteria to produce phosphatase. Therefore, observations of phosphatase activities are important to know how intensely P mineralization process takes place in the soil. Phosphate solubilizing rhizobacteria (PSR) has been widely known to affect mobilization of insoluble inorganic phosphates become available to plants. Although phosphate solubilizing rhizobacteria is widely available in the soil, their activity is usually not strong enough to compete with other bacteria commonly located in the root zone (rhizosphere). That is why, screening of phosphatase enzyme activity and various phosphate solubilizing ability to obtain better strains of bacteria are still needed. This study was conducted to determine the ability of phosphate solubilizing rhizobacteria, its potential as a biofertilizer inoculant and characterize its capacity to dissolve P-insoluble inorganic and produce phosphatase enzymes in the growing medium. Potential phosphate solubilizing rhizobacteria was tested for their ability in vitro using Pikovskaya media containing insoluble forms of inorganic phosphate as a source P. The results of this study indicate that there are some isolates phosphate solubilizing rhizobacteria that are capable of dissolving the insoluble inorganic-P with different abilities. The highest potential successively displayed by isolates TbPP-4.1; BdPP-2.1; and SBPP-1.3 that significantly has the same ability to soluble inorganic phosphate in the soil. The isolates BdPP-2.1 and TbPP-4.1 are significantly higher than the other isolates for producing phosphatase. Both isolates TbPP-4.1 and BdPP-2.1 have the same pontenty as a biofertilizer based on its capacity to mineralize forms of soil organic phosphorus by phosphatase activity.
