The function of humic acid fertilizer Ⅰ
Can improve the utilization rate of nitrogen fertilizer:
nitrogen fertilizer is an indispensable fertilizer for plant growth, mainly urea and carbon amine, when urea and carbon amine are applied to the ground soon after the loss of air and water, crops can really absorb the use of nitrogen element nutrients is only 30%. The aromatic core, hydroxyl group, carboxyl group and other acidic functional groups in humic acid can react with nitrogen elements to form very stable new ion groups. These complexes remain in the soil for a long time and gradually decompose and release nitrogen elements for plants to slowly absorb.
