Abstract:
     The production method for the manure contained microelements (Fe, Ca, Si, B, Mo and Zn) is presented in the invention. The manure with microelements which is made of slag ash, phosphorite powder, blende, dolomite, pyrolusite, borax, zeolite, kaolin and ammonium molybdate is put directly into the soil. The manure with microelements which is made of ferrisulphas, magnesium sulfate, borax, manganese sulfate, zine sulfate, copper sulfate, ammonium molybdate, nickel sulfate, strontium chloride and cobalt chloride is used for mixing the seed, soaking the seed, wetting the seedling and manuring outside the root. The manure with microelements provides efficiently the microelements for the crops.
