Abstract

This research aimed to determine the effectiveness of several types of liquid organic fertilizer (LOF) derived from plant waste and the dose of P fertilizer on the growth and yield of upland rice on degraded acid soil. The treatments consisted of two factors. The first factor (A) was several types of LOF consisting of A1 (control), A2 (LOF containing isolates of P-solubilizing bacteria), A3 (LOF-banana waste), and A4 (A2+A3). The second factor (B) was fertilizer doses consisting of B1 (50% of the recommended dose of P fertilizer), B2 (75% of the recommended dose of P fertilizer), and B3 (100% of the recommended dose of P fertilizer). The treatment combinations were arranged in a factorial randomized block design with three replications. The research results showed that applying either LOF-banana waste or the mixture of LOF-banana waste and LOF-containing isolates of P-solubilizing bacteria improved plant height, the number of tillers, and N and P uptake by the plant. The rice grain yields among the treatments were not significantly different, but the highest rice grain yield (139.8 g/pot) was obtained at the treatment of the mixture of LOF-P isolate + LOF-banana waste (A2+A3 treatments). The 75% of the recommended dose of P fertilizer was not significantly different from 100% P fertilizer with LOF on growth and yield upland rice and nutrient uptake by the plant.

Abstract

Ultisol is generally characterized by a high clay content in the argillic horizon, easy compaction, slow permeability, and unstable aggregates, resulting in low total porosity. Organic soil amendments such as compost and biochar can be used to improve soil organic matter, aggregate stability, and other physical properties of Ultisol. A field experiment was conducted using a randomized block design to assess the potential effects of Leucaena compost (LC) and coconut shell biochar (CB) on the physical properties of Ultisol and maize yield. The treatments included combinations of compost (0, 5, and 10 t/ha), biochar (0, 5, and 10 t/ha), and inorganic fertilizer (50% and 100% of the recommended dose). The results showed that the application of Leucaena compost and coconut shell biochar improved the physical properties of the soil. Compost and/or biochar applications at 10 t/ha enhanced soil organic matter, total porosity, aggregate formation, aggregate stability, pore size distribution, and reduced soil bulk density, improving maize growth and yield.

Abstract

Characteristics of the most prominent former coal mining land are severe damaged land, causing decreased soil productivity, erosion and sedimentation, soil movement and resulting in land slides, and soil compaction so that it is difficult to process. Efforts to improve the physical properties of coal mining reclamation soils, namely by adding biochar and compost. Biochar and compost can slot dana improve the physical properties of the soil by increasing the content of organic matter, total pore space, water เว็บสล็อต | R4shub content and reducing the weight of soil volume. This study uses a complete random design with 6 treatments and 4 replications. The treatment used in this study is B0 without treatment (control); B1 15 tons/ha biochar oil palm shells; B2 10 tons/ha biochar oil palm shells and 5 tons/ha of city waste compost; B3 7.5 tons/ha biochar oil palm shells and 7.5 tons/ha of city waste compost; B4 5 tons/ha Biochar palm oil shell and 10 tons/ha of city waste compost; B5 15 tons/ha of city waste compost. The observed variables are the content of organic matter, the weight of soil volume, total pore space, soil water content in several PF values, plant height, plant yields and the number of plant pods. The results obtained that the treatment combination of 7.5 tons/ha of biochar oil palm shells 7.5 tons/ha of city waste compost is the best composition to improve the groundwater content of coal mining reclamation. Furthermore, the provision of 15 tons/ha of city waste compost has effectively improved soybean yield. Keywords : biochar, compost, some physical properties, coal, soybeans

Abstract

Ultisol has a texture with a high clay content and a medium to high bulk density so it is susceptible to increasing soil compaction. High soil compaction indicates physical soil problems and inhibits plant growth. The application of soil amendments such as biochar and mycorrhiza can help be help improve soil compaction and support corn growth. This study aimed to examine the potential of biochar from palm fronds and mycorrhiza in improving Ultisol compaction and increasing corn yield. The research was conducted by using a randomized factorial design with 2 factors. The first factor was, oil palm frond biochar with 3 levels, no biochar (B0), biochar 5 tons.ha-1 (B5), and biochar 10 tons.ha-1 (B10). The second factor was mycorrhiza with 3 doses, without mycorrhiza (M0), mycorrhiza 10 grams (M10), and mycorrhiza 20 grams (M20). The results showed that the combination of oil palm frond biochar and mycorrhiza did not show an interaction in improving soil density, but had a significant effect on organic matter, plant height, and yield of maize plants. The application of biochar and mycorrhiza alone was able to improve the bulk density, soil porosity, penetration resistance and soil moisture content. The combination of 10 tons.ha-1 biochar and 20 grams mycorrhiza increased soil organic matter, plant height, and corn yield 66.74%, 24.77%, and 30.26%, repectively compared to the control. Thus, the combined application of oil palm frond biochar at 10 tons.ha-1 and mycorrhiza at 20 grams has the potential to improve soil organic matter content and increase corn yield.
