4.1 Technical plan of the technology

Methods of managing the plot for planting vegetables in areas with degraded soil and soil with

slightly amount of salinity as follows:

Cultivation plot preparation

1. Plough and blast soil, followed by plowing in regular furrows for the second time by using

a 65 HP tractor and a small Kubota tractor to disintegrate soil to become smaller and finer

2. Elevate the furrow for the dimension of 30 centimeters high and 60 centimeters wide. The
spacing between plots is 1 meter. Burn a pile of plant residues with the height of about 30

centimeters in the cultivation plot until it becomes charcoal with red spark to kill bacteria and

disease-causing fungi. After that, follow by watering it to extinguish the blaze.
3. Spread dolomite thinly for soil amendment with the rate of 25 kilometers per rai. This is

followed by using dung which is waste from pigs going through the process of gas fermentation at
the rate of 100 kilograms per rai. Incorporate together and use the bio-extract with the rate of 2

spoons per 20-liter water to help improve the soil and stimulate the growth of plant roots.
4. Mix the cultivation soil with the ratio of 3 handfuls of soil: 1 handful of dung.

5. Dry the soil for 7-14 days. Before planting, place a cut banana stem with the length of 10

centimeters at the bottom of the hole to mix with the soil in the planting hole.
