Aims: To optimize the dose of three ameliorants (biochar, lime, and compost) and their interactions on the availability of macronutrient P. Study Design: This research was a laboratory incubation study using soil samples from the newly opened rice fields. Place and Duration of Study: Paddy field of Ray 7, Balandean Village, Alalak District, Barito Kuala Regency, South Kalimantan Province from May to November 2021. Methodology: The study used factorial design with the treatments of 1) Biochar, with levels of 0, 10, and 20 t ha-1, 2) Lime, with levels of 0, 2, and 4 t ha-1, 3) Compost with levels of 0, 5, and 10 t ha-1. All were arranged in Completely Randomized Design with three replications. The experimental units were 300 g of soil sample in 81 of 10 cm plastic pots. They immersed up to 2 cm water and incubated to imitated field conditions for three months and then analyzed for the parameters. Results: Biochar and lime increased available-P quadratically and linearly following orthogonal polynomial analyses. Their interaction was highly significant in increasing available-P. The doses for both could be increased for the maximum availability of P. Conclusion: Biochar increased P availability with the tendency of increasing beyond the dose of the treatment. The main treatment of compost was not as good as biochar. However, when applied together with biochar and lime, compost affected the solubility of P. However, to increase P availability, the combination of the ameliorants showed a good synergism.

“…Oleh karena itu, diperlukan pengelolaan tanah yang dapat menjadikan lahan sulfat masam produktif berkelanjutan yang juga memperhatikan ciri fisik tanah (Masulili et al 2010). Sejalan dengan hal tersebut, temuan Masulili et al (2016) menunjukkan bahwa bioarang (biochar) berpotensi dalam meningkatkan pertumbuhan dan hasil tanaman padi (Oryza sativa) di tanah sulfat masam.…”

This study aims to determine the effect of various doses of rice husk biochar combined with organic amendments of cow manure and inorganic amendments of recommended fertilizer packages (urea, TSP, and KCl) on acid-sulfate soils. Over four months, the study was conducted in the Experimental Land of the Center for the Assessment of Agricultural Technology (BPTP) Pal IX, West Kalimantan Province. The study employed a randomized block design, with treatments including control soil, rice husk biochar 6 t ha-1, rice husk biochar 8 t ha-1, rice husk biochar 10 t ha-1, rice husk biochar 12 t ha-1, package of recommended inorganic fertilizer, package of recommended inorganic fertilizer + rice husk biochar 10 t ha-1, manure 10 t ha-1, and 10 t ha-1 + rice husk biochar 10 t ha-1. The findings revealed that single rice husk biochar amendments and their combination with inorganic and organic amendments had varying effects on the improvement of several physical properties of acid sulfate soils (density, total pore, moisture content, and penetration resistance). The amendment of a single biochar with a dose of 12 t ha-1 resulted in the lowest bulk density of acid sulfate soil, which decreased by 16% compared to the control soil. At a dose of 12 t ha-1, rice husk biochar produced the highest porosity and soil moisture content, 55% and 17%, respectively. The soil strength, as measured by the lowest penetration resistance, decreased by 30% in the treatment of manure 10 t ha-1 + biochar 10 t ha-1 (350 N cm-2) compared to the control soil. Keywords: biochar rice husk, soil amendment, soil properties of acid sulphate

“…In this connection, research by Masulili [2] has found that rice husk biochar can be used as an effective soil amendment to address acid soil problems in West Kalimantan, which can increase rice crop production. Masulili et al, also found that biochar coconut waste in acid sulphate soils in West Kalimantan could increase rice growth and yield [6].…”

The purpose of this research was to determine the effect of rice husk of biochar combined with inorganic and organic amendments on soil strength, growth and yield of rice plants on acid sulphate soils. The research phase was to identify the physical properties of soil in both regions and the measurement of field penetration resistance. Furthermore, conducting field research using a randomized block design (RBD), with the treatment consisting of; control soil (B0), rice husk biochar 6 t.ha-1 (B1), rice husk biochar 8 t.ha-1 (B2), rice husk biochar 10 t.ha-1 (B3), rice husk biochar 12 t .ha-1 (B4), recommended inorganic fertilizer package (B5), recommended inorganic fertilizer package and rice husk biochar 10 t.ha-1 (B6), 10 t.ha-1 (B7) manure fertilizer 10 t. ha-1 and rice husk biochar 10 t.ha-1 (B8). The research observations consisted of several physical properties of soil in BPTP land and farmer's land. Field penetration resistance is measured by determining the value of soil strength (DAIKI). Observation of growth variables in the maximum vegetative phase, consisting of; plant height and a number of tillers, while the yield variable is; a number of panicles per clump, and dry grain weight per clump. The results showed that the strength of the soil in the Experimental Field of BPTP West Kalimantan was 470 kPa and the farmer's land was 500 kPa. This condition indicated high soil compaction in paddy-based acid sulphate fields in the West Kalimantan Sungai Kakap.
