Calcium Magnesium Phosphate Fertilizer (also known as fused phosphate fertilizer) Phosphoric acid containing 14-18% Phosphoric acid. This grade is an efficient compound fertilizer with an active ingredient above 90%. It is non-toxic, non-corrosive and does not deliquescence. After agglomeration, the fertilizer effect remains unchanged after the damp. Active ingredients: P2O5 20% or more - P 14-18%. MgO 13% or more - Mg 7-9% SiO2 20% or more More than 50% CaO - Ca 35-36% Calculation method: purity = theoretical content / actual content Such as: MgO 13% (purity) = 60% (theoretical content of Mg in MgO mass fraction) / actual content Therefore, Mg%=MgO 13% (purity)*60% (mass content of theoretical Mg in MgO)=7.8% in calcium magnesium phosphate fertilizer The other calculation methods are the same, and they are not calculated one by one.
