ABSTRACT:
A liquid fertilizer composition which is storable for 6-8 months is prepared from an aqueous methylol urea containing solution and dibasic potassium phosphate. The methylol urea containing solution has a nitrogen content of approximately 15-35% by weight. The dibasic potassium phosphate adds the phosphorous and potassium components to form a complete fertilizer having a preferred N-P-K ratio of from about 6:1:1.33 to 18:1:1. It also stabilizes the methylol urea containing solution so that premature gelling and precipitation are avoided. As such, the liquid fertilizer is storable and easily applied through liquid application to a lawn.
