摘要：

THE EMBODIMENTS OF THE PRESENT INVENTION DISCLOSE A LIGNIN BASED WATER RELEASING FERTILIZER COMPRISING A CROSS-LINKED STARCH, DISODIUM TETRABORATE, LIGNIN AND UREA. THE FERTILIZER RELEASES WATER SLOWLY. THE EMBODIMENTS ALSO PROVIDE A METHOD OF SYNTHESIZING A LIGNIN BASED WATER RELEASING FERTILIZER. THE METHOD COMPRISES DISSOLVING A STARCH IN WATER, ADDING A PREDETERMINED AMOUNT OF UREA, ADDING A PREDETERMINED AMOUNT OF DISODIUM TETRABORATE SALT, ADDING A PREDETERMINED AMOUNT OF LIGNIN, KEEPING THE MIXTURE AT A TEMPERATURE OF 80ºC FOR 3 HRS, POURING THE MIXTURE ON A DISH AND DRYING THE MIXTURE FOR 2 HOURS AT A TEMPERATURE OF 120ºC TO OBTAIN THE FERTILIZER. MOST ILLUSTRATIVE FIGURE: FIG. 1
