Activities and details of the operation
1. Building water resources
Building water resources by digging ponds with the depth of 3.50 meters to collect rain
water falling within the area based on the calculation of soil surface runoff accounting for 30% of
the annual amount of precipitation and building plantation furrows with the dimension of 3 meters
wide and 2 meters deep to store water for water hyacinth (Salvinia cucullate) and frog spawn
culture
2. Apply water to build vegetation
Applying the stored water to build vegetation at the plantation area resulting from filling
soil by planting legumes, grass and farm plants. Then, allow these plants to cover the soil surface
throughout the year. At the plantation furrow, planting water hyacinth and frog spawn.
3. Use vegetation to manage saline soil
Using the growing vegetation covering the soil surface at the plantation area resulting from
filling soil to keep moisture in the soil continuously, improving the soil physical structure and
increasing organic matter to the soil. At the furrow ridge, using water hyacinth and frog spawn to
cover the soil surface to keep moisture in the soil. Improving the soil physical structure and
increasing organic matter including plant nutrients to the soil.
4. Using the area to produce cash crops
Planting various cash crops like fruit trees by experimenting with planting various plants
and selecting the variety which corresponds well with the area, namely pomelo, mangos,
jackfruits, Manilkara Kauki, rose apples, guava. bananas, custard apples, tamarind. The fruit tree
which is the main cash crop is pomelo and other kinds of fruits as supplementary plants. Moreover,
the area between rows is used to plant farm plants such as corn, watermelon, pumpkin, including
legumes etc.
