4. Environment
4.1 Property characteristics of the natural environment
The terrain is quite flat and 130-160 meters higher than the average sea level. Regarding
the climate, there are 3 seasons. The average lowest and highest temperature are 21°C and 35°C
respectively. It does not rain regularly. The average amount of rainwater is between 1,000-1,400
millimeters. The soil has rather poor water drainage and is more than 20 centimeters deep. It is
grayish brown and has spot with colors. The soil texture on the top is sandy clay loam. The soil
texture at the bottom is silt clay loam. The soil is Thung Kula Ronghai soil series (Ki) influenced
by salt in the category of Maha Sarakham rock. The ground water cannot be used. The water at
the soil surface is at a medium level. However, due to the water quality, the water can be used for
agriculture only. However, water salinity is an important problem in conducting farming. As a
result, only certain plants can be planted and low yields are obtained.
4.2 Impact in the on-site from using the technology
1. Economic and social impact
Aspect Impact Before After
1. Crop production Increased at Products of 100 kilograms Rice products of 5,000
the most were obtained from crop kilograms per round of
production for 0.16 ha production are obtained.
(2.08 ha = 1,300
kilograms) because the
soil was very saline
resulting in low
production of rice.
2. Cultivation Increased at Only a small quantity of When the planting system
qualities the most the rice product was is changed to be suitable
with soil conditions,
