| Popis: | 107 To reduce the impact of labor shortage in iceberg lettuce production, the preparations of slow-released fertilizers using water hyacinth and turtle shell powder modified by biochar or vinegar were developed. In the beginning, the suitable condition, such as the acid-base and electrical conductivity values, of planted soil for iceberg lettuce growth was studied. The natural agricultural industry by-products, water hyacinth and turtle shell powder, are employed for slow-release fertilizers. The effect of micro-particle capsulation and matrix dissolution rate on chemical agents such as modified water hyacinth and compound fertilizer was investigated to find out the optimal methods for preparation of slow-released fertilizers. |
