Turfgrass fertilizers with slow-release formulations can be derived from natural organic sources (including manures, composts, bloodmeal, food industry by-products, yard wastes, etc), or derived by reacting urea with various organic or inorganic compounds to form ureaformaldehyde (UF) isobutylidene diurea (IBDU), and sulfur or poly coated urea (SCU, PCU). These slow-release formulations offer these advantages for use on turfgrass:
Release of nitrogen from organic fertilizers is dependent primarily on microbial activity. Depending on conditions, nitrogen release from organic fertilizers can be relatively rapid or may be immobilized within the soil organic matter and not released for many months.
