1. A liquid fertilizer composition, comprising a silicate base composition between 10% to 98% (w/w) and additional ingredients,
wherein the silicate base composition comprises:
potassium silicate, at a concentration between 50% to 90% (w/w);
a pH regulator, at a concentration between 5% to 17% (w/w);
an emulsifier, at a concentration between 1% to 20% (w/w);
water between 1 to 42.95% (w/w);
a dispersant, at a concentration between 0.05% to 25% (w/w);
an antifreeze, in a concentration between 1% to 15% (w/w);
wherein the additional ingredients comprise copper sulfate, zinc sulfate, calcium hydroxide, phosphorous acid, potassium carbonate, boric acid, urea, fulvic acid, amino acids, EDTA, xanthan gum, potassium sorbate and water; and
wherein the silicate base composition is a suspension characterized by a pH between 4.5 to 6 and a potassium silicate particle size between 5 to 40 μm.
