Abstract

The invention provides an organic-inorganic composite fertilizer, in particular a quick dissolving fertilizer containing nitro ammonium humate and method for preparation, wherein the weight portion of the constituents include, nitro based humic acid 10-50%, urea 0-40%, ammonium nitrate or ammonium sulfate 0-10%, ammonium phosphate 0-35%, potassium sulphate 0-20%, magnesium sulfate 0-5%, zinc sulfate 0.5-1%, and borax 0.3-0.8%.

Description

technical field [0001] The invention relates to an organic-inorganic compound fertilizer used in vegetable production, in particular to an instant fertilizer containing ammonium nitrohumate and a preparation method thereof. Background technique [0002] In vegetable production, due to the short growth time of vegetables, and at the same time, in order to obtain high yields, farmers put too much chemical fertilizers into the vegetable fields, accumulating throughout the year, the land is knotted, and various diseases are aggravated. Water pollutes groundwater. [0003] In the prior art, conventional chemical nitrogen fertilizers have good water solubility and are easily lost after being applied to the soil. Ineffective state (especially in calcareous soil); therefore, it is necessary to develop and produce slow and controlled release fertilizers that can maintain the long-term effect of nitrogen fertilizer and reduce the fixation of phosphorus fertilizer.
