Abstract

Most of the activities of the use of organic fertilizers and natural additions of organic matter in agricultural intensification fields in Indonesia have not been able to compensate for the rate of decline in soil organic matter by the decomposition process. Biochar has a high C level and has the mean residence time in a long period in the soils. It has been proven that biochar applications may increase soil Carbon but have not been able to increase plant production. Therefore, the use of biochar combined with organic waste rich in nutrients is essential to develop. The purpose of this study was to determine the effectiveness of some biochar compositions with sugar cane, chicken manure, fish waste in the form of biopellet fertilizer on improving the chemical properties of sandy soils and the vegetative growth of soybean plants. This study used a completely randomized block design with two factors. The first factor (B) was the composition of biochar consisting of three levels, namely: 70% biochar, 15% chicken manure, 15% fish waste (B1), 50 % biochar, 25% chicken manure, 25% fish waste (B2), and 20% biochar, 40% chicken manure, 40% fish waste (B3). The second factor (D) was the dose of biopellet fertilizers consisting of four levels, namely: control (D0), 2.5 t/ha (D1), 5 t/ha (D2), and 10 t/ha (D3). The results showed that the addition of biopellet fertilizer effectively improved soil chemical properties (pH, C-organic, and CEC) and the availability of N, P, and K of the sandy soil. The effectiveness of increasing the soil total-N varied from 32.42 to 75.79%, P-available varied from 17.46 to 40.69%, and exchangeable K ranged from 8.7 to 25.67%. Improvement of soil chemical properties and the availability of N, P, and K by biopellet fertilizer application increased plant growth but reduced the weight of root nodules.

Abstract

Phosphorous (P) contents in many soils are varies highly along with their ability to provide available P to plant growth. Soils may contain very high in total P, but low in available P due to high P adsorbed by soil matrix and all their adsorbing agents. This research which using natural materials was aimed to increase P availability in some high-P absorption soils. The natural materials utilized for extracting P were organic matter, P extracting bacterial, and rock phosphate. Those materials were interacted to high P absorption soils which were: Oxisol, Inceptisol, and Andisol. The detail objectives of this research were: (1) to study the potential of P-extracting agents (organic matter, and P-extracting bacteria) in releasing P of three high P- absorption soils; (2) to quantify the -age of P coming from the treatments; (3) to calculate the efficiency of P utilization by plant; and (4) to quantify Residual P in soils. The P mobility was analyzed by radioisotope technique using KH232PO4 carrier free solution. The results showed that adding soil organic matter increased the available P by 15.24% in Oxisol, 40.18 in Inceptisol, and by 7.34% in Andisol. Plant sorption toward P from % P used efficiency(%-PUE) up to 60 days was still very low, 0.65 to 9.34%. This was in accordance with the residual P in soils which were still quite high ranging from 94% to 96% in Andisol, 91%97% in Inceptisol, and 96%-98% in Oxisol. The implication of the results of this research, however, is that the application of natural materials in improving soil P availability provides a longtimeresidual effect which could give benefit to the following crops.Keywords: Andisols; Inceptisol; Oxisols; P. diminuta; PUE;  rock phosphate[How to Cite: Mudjiharjati A, TC Setiawati and MH Pandutama. 2012.

Abstract

Biochar is a highly resistant source of carbon to the decomposition process so it can storecarbon in the long term and improve soil characteristics. However, the macro nutrientcontent in biochar is so low that it has not been able to increases soybean plant prductionespecially its dry weight, thus lowering the root nodules. Therefore, biochar needs to beenriched with nutrients, especially NPK, adjusting the requirement of soybean plants bycomparison (8: 5,1: 4) in biochar. The addition of inappropriate nutrients especially nitrogenwill also affect the development of root nodules. Therefore, this study aims to determine (1)the effect of enriched biochar on soil properties, (2) the effect of soil properties on soybeanroot nodules, (3) the best combination of biochar and NPK in improving the development ofroot nodules. This research was conducted using Factorial Randomized Block CompleteDesign (RBCD) consisting of two factors with three replications. The first factor (B): Biocharsource, consisting of four levels and then the second factor (D): Enriched Biochar Dose,consisting of four levels. Based on the correlation result, the root nodules is significantlyinfluenced by soil pH, total N, N uptake, P uptake, and K uptake in acid soil, while measuredphysical and biological characteristic have not significantly influence. Total N and N uptakehave negative correlation so that its enhancement will reduces development of root nodules.The results show that enriched biochar is not significantly influential in increasing total soilN, while significantly reduces soil pH. In soybean crops, enriched biochar significantlyinfluences N, P, and K uptake, vice versa significantly reduces root nodules at doses greaterthan 2.5 ton / ha. The best combination was found in 2.5 ton / ha dose of rice straw biocharand wood biochar for optimize development of root nodules
