Abstract

Nowadays the innovations in organic agriculture systems continue to be developed to achieve a sustainable agriculture system. In Indonesia with high rainfall, nutrient loss is still a major problem. The application of zeolite and manure as a soil amendment is expected to increase nutrients available in soil and cation exchange capacity of the soil in the long term. The results on the first planting season showed a significant increase in chemical soil fertility. The objective of this study is to research the effect of residue zeolite and manure on soil chemical fertility and yields of the second planting season. This study used a complete randomized block design. The factors were a dose of zeolite (Z1: 2.5 tons ha -1; Z2: 5 tons ha-1) and kind of manure (P1: quail manure; P2: cow manure), with three replications. The result showed that zeolite treatment of 5 tons ha-1 and cow manure increased the total N soil by 27.78% and 45.4% compared to the control. The treatment of quail manure increased soil organic matter 78.78% compared to the control. The treatment of cow manure increased the green bean yield 28.76% compared to the control.

Abstract

Soil organic matter (SOM) is one of the important parameters in agriculture management, thus estimating its distribution on the land will be essential. Remote sensing can be utilized to map the SOM distribution in the large-scale area. The objective of this research was to determine the estimation of SOM distribution on the paddy field in Sukoharjo Regency, Indonesia using Landsat 8 OLI imagery. The sampling points were determined by purposive sampling based on an overlay of land use classification map of paddy field, NDSI (Normalized Difference Soil Index) map, and soil type map. The analysis method was used simple linear regression (SLR) and multiple linear regression (MLR) between SOM content and a digital number of Landsat 8 OLI imagery. The SLR analysis resulted that all band except band 1 and 5 of Landsat 8 OLI Imagery have the capability to estimating SOM. The MLR model based on best subset analysis resulted in the combination of bands 3, 4, 6, and 7 was the best model for estimating SOM distribution (R2=0.399).  The MLR model was used to create SOM distribution map on paddy field in Sukoharjo Regency and resulted in the SOM range of the area is distributed from very low (<1%) to moderate (2.1–4.2%) with the largest area was on low level (1–2%) about 11,028 ha. The result indicates that Landsat 8 OLI Imagery could be used for mapping the SOM distribution.

Abstract

Arbuscular mycorrhiza (AM) is known as multifunctional fungi for plant helpers under adverse conditions. However, studies that focused on the production strategy of AM biofertilizers with specific targets related to the soil limitations are limited. This study aimed to examine AM inocula from several sources using various compositions of acid mineral soil-based media and maize hosts in pot cultures to obtain effective AM inocula to handle the phosphor (P) limitations in acid mineral soils. Zeolite and Inceptisols were used as comparing media. The study utilized a completely randomized factorial design with two factors, namely C = media composition (C0: zeolite; C1: representative media of Alfisols; C2: typical media of a mixture of Alfisols, Oxisols, and Ultisols; C3: typical media with the addition of Bio-RP nutrition; C4: Inceptisols) and I = AM inoculum source (I0: without inoculum; I1: inoculum from Alfisols; I2: mixed inoculum from Alfisols, Ultisols, and Oxisols; I3: mixed inoculum from eight soil types), and six replications per treatment combination. The AM cultures on acid mineral soil-based media, which yielded the highest mycorrhizal infection, spore reproduction, and glomalin content, were C1I2 and C3I2, while the highest maize growth and P concentration were obtained with C1I1, CII2, C2I1, and C3I2. Compared to all the treatments, C1I1 and C1I2 are the superior AM cultures. Further study is necessary to confirm the effectiveness of AM cultures.
