PT Yanmar Diesel Indonesia, Faeger, and IPB University have initiated a collaborative research project in Indonesia evaluating how combining controlled irrigation with biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More application can mitigate greenhouse gas emissions from rice paddies without compromising crop yields. Launched in April 2026 at an experimental field facility operated by IPB University, the multi-stakeholder trial integrates Alternate Wetting and Drying (AWD) water management with soil incorporation of carbon-rich agricultural amendments. By testing these practices in parallel, the partnership seeks to establish a scalable, low-carbon rice production framework suitable for adoption across Southeast Asian agricultural systems.

The joint initiative targets the significant environmental footprint of traditional flooded rice farming, which generates substantial atmospheric methane emissions due to prolonged anaerobic soil conditions. In addition to high methane outputs, regional post-harvest supply chains generate vast volumes of unutilized agricultural residues, particularly rice husks from milling operations, which are frequently burned or discarded. Conventional paddy management fails to address these dual sustainability bottlenecks, leaving farming communities vulnerable to soil degradation while contributing to agricultural carbon emissions.

To resolve these systemic operational hurdles, the research team implemented an integrated intervention that combines intermittent field drying with the application of pyrolyzed rice husks. The AWD protocol periodicially drains flooded paddies to disrupt anaerobic microbial activity and suppress methane generation, while the addition of rice husk biochar enhances soil carbon storage, improves soil structure, and increases nutrient and water retention. By utilizing locally sourced mill residues, the project establishes a circular agricultural loop that repurposes crop waste into durable soil amendments.

The research endeavor aims to generate empirical data on methane reduction efficiency, carbon sequestration capacity, and overall agronomic productivity to support low-emission rice farming frameworks across Indonesia and surrounding tropical regions. The resulting scientific data is expected to establish baseline standards for future agricultural carbon-credit projects, offering farmers potential secondary revenue streams through verified carbon accounting. Through this field validation, the partners demonstrate a practical pathway for decarbonizing food production while improving agricultural resilience and soil health.
