Abstract
A homogeneous, zinc-containing liquid fertilizer concentrate is prepared by mixing, in aqueous solution, ammonium thiosulfate and zinc oxide. This zinc-containing concentrate is suitable for mixing with a liquid fertilizer preparation such as aqueous ammonium polyphosphate to prepare a complete zinc-containing fertilizer solution. The nutrient value of the concentrate and the fertilizer can be enhanced by the addition of a potassium salt or nitrogen solution. The long-term stability of the fertilizer solution can be improved by the addition of attapulgus clay.
