Green-T® 30-0-0, 60% SRN is a clear liquid slow-release nitrogen fertilizer. A total of 60% of the nitrogen is composed of slowly available urea polymers in the form of methylene urea and triazone. The remaining 40% is composed of urea. The nitrogen in Green-T® 30-0-0, 60% SRN is released in the soil over 60 to 90 days depending on soil type and climatic conditions. Microbial breakdown is required to release nitrogen from the urea polymers, and this may be affected by soil temperature, moisture and oxygen concentration. Green-T® 30-0-0, 60% SRN was developed have high stability when blended with certain formulations of phosphorus, potassium and micronutrients.
