2. Controlled-release fertiliser - Wikipedia

   en.wikipedia.org/wiki/Controlled-release_fertiliser

   Slow- or controlled-release fertilizer: A fertilizer containing a plant nutrient in a form which delays its availability for plant uptake and use after application, or which extends its availability to the plant significantly longer than a reference ‘rapidly available nutrient fertilizer’ such as ammonium nitrate or urea, ammonium phosphate ...

3. Fertilizer - Wikipedia

   en.wikipedia.org/wiki/Fertilizer

   Controlled-release fertilizer is also known as controlled-availability fertilizer, delayed-release fertilizer, metered-release fertilizer, or slow-acting fertilizer. Usually CRF refers to nitrogen-based fertilizers. Slow- and controlled-release involve only 0.15% (562,000 tons) of the fertilizer market (1995).

4. Organic fertilizer - Wikipedia

   en.wikipedia.org/wiki/Organic_fertilizer

   Organic fertilizer nutrient content, solubility, and nutrient release rates are typically much lower than mineral (inorganic) fertilizers. [ 38 ] [ 39 ] A University of North Carolina study found that potential mineralizable nitrogen (PMN) in the soil was 182–285% higher in organic mulched systems than in the synthetics control.

6. Soil fertility - Wikipedia

   en.wikipedia.org/wiki/Soil_fertility

   Slow-release fertilizers may reduce leaching loss of nutrients and may make the nutrients that they provide available over a longer period of time. Soil fertility is a complex process that involves the constant cycling of nutrients between organic and inorganic forms.

7. Coated urea - Wikipedia

   en.wikipedia.org/wiki/Coated_urea

   Sulfur-coated urea, or SCU, fertilizers release nitrogen via water penetration through cracks and micropores in the coating. Once water penetrates through the coating, nitrogen release is rapid. The particles of fertilizer may in turn be sealed with wax to slow release further still, making microbial degradation necessary to permit water ...
