Slow-release fertilizers (SRF) provide a steady supply of plant nutrients over an extended period of time.
They contain plant nutrient(s) (mostly nitrogen) in a form that delays their initial availability.
Due to that fact real slow-release fertilizers are providing a sustainable and continuous N supply for up to 4 months even in uncertain weather conditions.
Benefits
Temperature/humidity dependent nutrient release
Continuous N supply for up to 4 months
Steady growth = No growth peaks
Low salt concentration and toxicity
Reduction of burning risk
Less leaching
Promotes a good root system
Savings in labor, time and energy
