Specifications︰ Total Nitrogen(TN)38%-40%
Water Insoluble Nitrogen(WN)14-24%
Urea Nitrogen 3-5%
Activating index(AI) 40-70%

Advantages︰ Its releasing period reaches 80-350 days, the nutrients releases slowly with longer fertilizer effects, also with a high usage of Nitrogen, which is over 80%. It could proportionate the fast effects and slow release nutrients in the fertilizer according to the fertilizer-absorbing characteristics of different plants, which could make the nutrients releasing speed lined up with the plant-needed fertilizer content, reaching the effect of instant fertilizer to satisfy the nutrient requirement of the plant in whole growth period.
