Water susceptible to rhizobium disease, root rot, water, easy to lose water, so that root and leaf development is not complete, the number of growing seedlings is difficult to guarantee a serious impact on the season seedlings, a waste of resources, delayed production. I have worked in steel mills, there is a kind of insulation material called carbonization
