Abstract: A complete, non-burning, liquid fertilizer suspension, releasing nitrogen as required by plants without damage by high concentrations of contained nitrogen, comprising highly polymerized urea-formaldehyde, water soluble sugars, aliphatic alcohols, and water. To achieve desired properties solids content totals 50-70% by weight; sugars, 3 to 10%; alcohols, 0.05 to 1.0%; and urea to formaldehyde mol ratio is 1.7 to 2.3. Said composition retains pH of 6 to 7, viscosity of 200 to 350 centipoises, and stable suspension character until applied, and then stimulates growth of plants, particularly grasses.
