Abstract
Solid compound fertilizers for dissolving into stock solutions advantageously employing urea phosphate as a phosphorous source. The use of urea phosphate makes it possible to have calcium present as well as nonchelated trace metals without precipitation.
Claims18
A dry solid fertilizer composition consisting of an unheated admixture of about 1% to about 95% by weight of a non-polymerized dry urea phosphate and about 1% to about 95% by weight of dry calcium nitrate or calcium chloride, said urea phosphate and said calcium nitrate or calcium chloride being present in said dry solid composition in an amount sufficient to enable formation of a stable, essentially precipitate free concentrated aqueous solution containing about 2% to about 40% by weight of said fertilizer composition by dissolving said dry solid composition in water.
A dry solid fertilizer composition consisting of an unheated admixture of about 1% to about 95% by weight of a non-polymerized dry urea phosphate and about 1% to about 95% by weight of dry calcium nitrate or calcium chloride and about 0.1% to about 50% by weight of a non-chelated micronutrient trace metal salt, said urea phosphate and said calcium nitrate or calcium chloride being present in said dry solid composition in an amount sufficient to enable formation of a stable, essentially precipitate free concentrated aqueous solution containing about 2% to about 40% by weight of said fertilizer composition by dissolving said dry solid composition in water.
A dry solid fertilizer composition consisting of an unheated admixture of about 1% to about 95% by weight of a non-polymerized dry urea phosphate and about 0.1% to about 50% by weight of a sulfate, chloride, nitrate or lignosulfonate salt of a micronutrient trace metal selected from the group consisting of iron, magnesium, manganese, boron, molybdenum, copper and zinc, said urea phosphate being present in said dry solid composition in an amount sufficient to enable formation of a stable, essentially precipitate free concentrated aqueous solution containing about 2% to about 40% by weight of said fertilizer composition by dissolving said dry solid composition in water.
