The serious effects of sand gold mining on soil fertility were reported in this paper.These effects include
the structure of soil section was broken
gravel and bottom soil were reversed to surface soil
the nutrients of top tilling soil lost serious
the soil fertility and crop fertility and crop yield decreased.With the above results
the authors suggested that the keys of soil fertility conservation in soil reclamation should be to come off soil layer by layer and to place the topsoil alonely in sand gold mining.The heart of the matter is to carry on artificial plough in place the topsoil alonely in sand gold mining.The heart of the matter is to carry is to carry on artificial plough in paddy soil reclamation in the sand gold mine region of south China.
