PURPOSE:To effectively prevent sedimentation by incorporating K2SiO3 and trace elements into the liquid fertilizer and making the liquid soluble by using ethylenediamine tetraacetic acid. CONSTITUTION:Trace elements of Zn by <=0.02%, Cu <=0.02%, Mo by <=0.06%, Fe by <=2%, etc., and ethylenediamine tetraacetic acid by 2 to 10% are dissolved in an aqueous solution of K2SiO3 containing 70 to 40 parts by weight of K2SiO3 and 30 to 60 parts by weight of water to obtain the liquid K2SiO3 fertilizer with >=pH11. This fertilizer is to be diluted by 500 to 2000 times for use. |
