Thailand has domestic activity in mining coal lignite mined took up use of lignite coal, especially in the Mae Mo, Lampang. In the process of mining, it scrapped production occurs, especially information that is classified as mineral chandin earthwork in the sand where it will be taken to landfill in an area that is defined for the following areas to refresh. In this soil contamination left behind coal insert. The rest is from mining, but it will increase more and more every day until it becomes a big problem, with the mines. Later it was the turn of some of the damage that can occur. Overseas research has been done to exploit and increase the value of that scrap and found in the soil contamination data of coal. , Which later has been called "Leo fan dai (Leonardite)" (evolution grow thin, d.SC., continuum, and the Republican battle suk jinda jewel, TOKE, 2552 (2009) ml). There are elements that are very useful products, which consists of three main elements: humic acid (Humic acid) acid yufuin Chase (Fulvic acid), hip (Humin) and metal wamin. an element by humic acid fan dai with Leo kapen. thus applied to agricultural interests to increase the fertility of the soil property of Leo fan but since there is acid values dai-alkaline (pH) is very low, about 2.31, the possibility of high acid and phosphorus. There is a very low value (< 0.50 P2O5) (company. Filter central laboratory (Thailand) co., Ltd., 2556 (2013)) The current most popular Cantonese vegetable chemical fertilizer and chemicals used in Guangdong has accelerated, growth and stem the fast enough so that with people's consumption. Farmers have high production costs because they require the use of chemicals and chemical fertilizer in planting. It is harmful to consumers, including chemical manufacturers to get into. To take advantage of a Leo fan, so as an alternative for dai farmers produce vegetables of Guangdong to reduce the cost of production of vegetables, Cantonese, including resource management, soil fertility, and help solve problems in the long run. So it was an appropriate rate of education Leo fan dai in Cantonese vegetable to be useful to farmers or those involved further.
