Miss On-uma Leelanoi
Position: Owner of Na Mun Mang Ta Yai Farm and Community Researcher collaborating with Arsom Silp Institute of the Arts.
On-uma (or Mae On) is a mother of a student, 3rd batch at Pudalay Mahavijalaya School (Agri-Nature Based Alternative Education) She graduated with a bachelor's degree in 2022 from Arsom Silp Institute of the Arts in the field of Social Entrepreneurship (SE) with Philosophy of Sufficiency Economy. Her graduation project was an area design work by applying new theoretical principles to solve the salinity problem to develop her own area and became a sample plot called “Na Mun Mang Ta Yai” (meaning the inheritance of land that grandparents give to their grandchildren).
In 2023, she furthered her commitment to environmental stewardship by participating in the Royal Project with one of the six Araya-Kaset District Project (Sustainable Agronomy), solving soil salinity issues at Chaturaphak Phiman District, Roi Et Province, Thailand in order to develop a process to help solve the soil salinity problem for other plots in the future advancing sustainable agricultural practices and improving the livelihood of local communities.
Halt Soil Salinization
Saline Soil, Brackish Water
Saline Soil
Fertile Soil
Salinity from underground salt layers dissolves into the water, making it too salty for aquatic life and unsuitable for crop production.
Sunlight heats the soil surface, causing water evaporation that draws salt from underground salt domes to the surface, forming visible salt crystals.
Improving saline soil through Agri-Nature involves covering the soil with organic and various natural matter and adding beneficial microorganisms using dry and liquid compost.

Designing Rice Field Systems with "Na Kha Wang"
Cooperative Production System
Self-Reliant Farming
Using the principle of fresh water to press down on the clay soil, preventing the underground salt layer from dissolving and rising to the surface, combined with washing away the salinity.
A traditional method known as “Long Kaek" for harvesting rice, which maintains the relationships among farmers and networks, reduces costs, and fosters a strong community through mutual support.
Prioritizing household self-sufficiency by practicing organic rice farming. This reduces production costs, chemical expenses, and fertilizer and pesticide costs. It shifts food production system from dependence on large markets to self-reliance and mutual support within the network.
