Mechanism of Microbial Degradation of Slow-Release Fertilizers
Journal of Polymers and the Environment, 2000Methyleneureas are condensation products of urea and formaldehyde of different molecular mass and solubility; they are used in large amounts both as resins, binders, and insulating materials for industrial applications, as well as a slow-release nitrogen fertilizer for greens, lawns, or in bioremediation processes.

APPLICATION OF SMART HYDROGELS FOR SLOW RELEASE OF FERTILIZERS
MacroFrontiers 2025: 3th International Conference on Macromolecular CompoundsThe excessive consumption of fertilizers has been a major concern for agriculture. Based on the 2005 National Fertilizer Recommendation Guide, on average, farmers overuse urea and fertilizer use has risen by 400% in the last 30 years (Rahman & Zhang, 2018, pp.

A SLOW-RELEASE FERTILIZER FOR NURSERY PLANTS IN CONTAINER
Acta Horticulturae, 1982During three years at three locations, experiments with a shrub (Pyracantha) and a conifer ( Chamaecyparis or Cupre ssocyparis), grown in containers, were carried out to establish whether the slowrelease fertilizer Osmocote 18+6+12 with a release period of 8-9 months, mixed through the potting soil as a basal dressing at the start of the season, could ...

Turfgrass Response to Slow‐Release Nitrogen Fertilizers
Agronomy Journal, 1997AbstractNew polymer coatings have been developed and used to coat sulfurcoated urea (SCU) and other core N materials. These polymer‐coated S‐coated ureas (PCSCU) and polymer‐coated S‐coated N‐P‐K fertilizers (PCSCF) require evaluation for their N‐release properties turfgrass culture.
