Part 1: Rice Field Research
Research Period: 26 June 2568 – 14 November 2568 · 5 Experimental Plots
Nong Ma Mong Subdistrict Municipality, Nong Ma Mong District, Chai Nat Province conducted field research and trials in real agricultural environments in collaboration with Finorfin Co., Ltd., covering the full cycle from planting and cultivation through to completed harvest.
Trial Conditions: ST BIO was used as the sole bio-based input throughout the entire process. No chemical fertilizers and no chemical pesticides were used in any of the 5 experimental plots. Each plot was paired with a control plot for comparison.

Research Summary — Rice
ST BIO yields outperformed chemical use in all 5 experimental plots
Across 5 sample plots, yield increased by approximately 8–50% per plot, with an average increase of approximately 33% compared to chemical use. No environmental impact was observed, and results are suitable for real-world deployment at the municipal level.
Part 2: Sugarcane Field Research
Research Period: 4 September 2568 – 31 January 2569 · 2 Experimental Plots
Building on the rice project into a "Chemical-Free Sugarcane Cultivation Project", carried out by Mr. Thawon Insupha, Municipal Member of Nong Ma Mong Subdistrict Municipality, at Ban Mai Khlong Khian Subdistrict, Ban Rai District, Uthai Thani Province.
Sugarcane planting began in May B.E. 2568 and harvest was completed in January B.E. 2569, with a total growing period of 9 months from planting to harvest.
