Preparation of Microcapsules of Slow-Release NPK Compound Fertilizer and the Release Characteristics

In this study, a novel type of slow-release fertilizer (SRF) was synthesized through lignin-based microcapsules. K2HPO4 and urea were coated by lignin and formaldehyde to prepare microcapsules of NPK compound SRF. The slow-release performance was measured by determining the NPK contents in water sol...
