Beschreibung
Zusammenfassung:The invention relates to a coated controlled release fertilizer and a production method thereof. The coated controlled release fertilizer comprises a granulated fertilizer containing water soluble nutrients, a granulated fertilizer surface treating agent and a granulated fertilizer coated layer. The coated controlled release fertilizer has the advantage that raw membrane materials are spread on the surface of the granulated fertilizer more evenly by improving the performance of the raw membrane material and treating the fertilizer surface to obtain a controlled release fertilizer with a thinner membrane layer, so that the market requirement is met at lower cost.
