Putu Oki Bimantara, S.P., M.Agr. is an Assistant Lecturer at the Faculty of Agriculture, Udayana University, specializing in Soil Science, Soil Fertility, and Sustainable Agriculture. He earned his Bachelor’s degree in Soil Science from Gadjah Mada University (2017) and his Master’s degree in Agriculture (Bioresource Science) from Yamagata University, Japan (2020). His research focuses on soil carbon and nitrogen dynamics, organic matter management, mitigation of greenhouse gas emissions (CH₄ and N₂O) from paddy ecosystems, and development of locally adapted sustainable farming systems.

Over the past five years, he has been actively involved in numerous research projects funded by Udayana University (PNBP), regional research agencies, and international collaborations. His major research topics include:

  • Azolla and poultry-litter biochar management for improving soil fertility, nitrogen use efficiency, and reducing CH₄ and N₂O emissions from flooded rice paddies (published in Soil Science and Plant Nutrition, Heliyon, and Biochar).

  • Carbon and nitrogen dynamics under land-use change from paddy fields to upland, orchard, and parking areas, analyzed through lysimeter block experiments and stable isotope techniques.

  • Utilization of agricultural and livestock waste (such as clove leaves and cow manure) as compost materials to enhance the growth and quality of plantation crops.

  • Development of organic farming standards for rice cultivation under the project “Model of Standardized Organic Rice Cultivation in Bali” (BRIDA Bali, 2025).

  • Land suitability evaluation and organic fertilizer quality assessment across seven districts in Timor-Leste in collaboration with the Ministry of Agriculture and Fisheries (MAF) Timor-Leste.

  • Assessment of total carbon sequestration in Subak rice fields within the Yeh Ho Watershed, Bali, contributing to climate change mitigation efforts.

In addition to research, he has contributed to community service programs focusing on women’s agribusiness innovation, orchid acclimatization using colchicine, and sustainable farming education for local farmers.

He has published more than 13 peer-reviewed international journal articles, and received several academic honors including the Best Poster Award (2018), Graduate School Alumni Award (2019), and Best Research Award (2020) from Yamagata University. His current research direction involves natural biostimulant development and digital solutions for agricultural supply chain governance in Bali through cross-national collaboration.
