e030003M Study on improvement of extreme acid soil was successful. Soil can use for agriculture , rice, vegetation. This improvement process gets good cost-benefit ratio.

Furthermore Pi Kun Thong Research and Development Study Center has studied to improve the acid soil by using fresh water clean up and put some Marl lime (CaCO3-impurities) mixed with the soil. Soil chemical will be changed.

Using two methods parallel, it was found that the collected water in plot 4 weeks and drained it out .After that pumped fresh water into plot and left it 4 weeks and pumed it out again. Rice production is satisfy. Marl lime (CaCO3-impurities) can reduce acid value.Two methods can use together and it must be faster.
