The Surjan system offers a multi-faceted approach to agricultural land management, particularly effective in dealing with inundation issues while increasing crop diversity. Our research focused on Surjan system lands in the Kulonprogo area, incorporating both observational methods and farmer interviews to glean a comprehensive understanding of the system’s impact on soil and gas emissions. The Surjan system comprises two primary features: "mound," which refers to raised beds suitable for horticultural and dryland crops, and "tabukan," sunken beds ideal for rice and rice-fish farming systems (mina padi). One of the most notable environmental benefits of this system is its role in flood prevention, reducing eutrophication and greenhouse gas emissions. Soil analysis showed variations in pH, redox potential, and organic matter, indicating that the system has a distinct impact on soil chemistry. Specifically, the pH ranged from 6.65 to 7.69, redox potential varied from −49 to 10 mV, and organic matter spanned 1.28% to 3.59%. Perhaps most interestingly, methane gas emissions from land managed through the Surjan system were significantly lower than those from conventional rice fields. Emissions ranged from 4.06 - 45.73 µg /m2/ minute, presenting a promising avenue for reducing the agricultural sector’s environmental footprint |
