Problems solved by technology

[0003] Although traditional chemical fertilizers such as diammonium phosphate, ammonium bicarbonate, and ammonium sulfate can be directly absorbed by plants, the disadvantages are fast volatilization, low utilization rate, less plant absorption, and environmental impact.
Urea belongs to the amide nitrogen fertilizer, because it needs three-step transformation in the process of decomposition in the soil: the first step is to release urease from bacteria, fungi, and actinomycetes, and urease decomposes urea to form ammonium carbonate and ammonium bicarbonate , and they are easily decomposed into ammonia, carbon dioxide, water, and are easy to volatilize in large quantities, causing di

Abstract

The invention relates to a fertilizer synergist, the process for preparation and use for combining with fertilizers, which comprises 50-70 wt% humic acid and 30-50 wt% tracer element composition, wherein the tracer element composition comprises (by weight ratio) calcium sulphate 35-70%, magnesium sulfate 10-20%, borax 0.5-1%, ferrous sulfate 2.75-5.5%, manganese sulfate 0.5-1%, zinc sulfate 0.5-1%, copper sulfate 0.5-1%, ammonium molybdate 0.25-0.5%.

Description

Technical field: [0001] The invention relates to a synergist, in particular to a fertilizer synergist, its preparation method and application. Background technique: [0002] At present, human beings are facing serious challenges such as population growth, reduction of arable land, and environmental pollution. In order to meet people's growing demand for food and other agricultural products, production must be increased, and the application of chemical fertilizers is the main means of increasing agricultural production. [0003] Although traditional chemical fertilizers such as diammonium phosphate, ammonium bicarbonate, and ammonium sulfate can be directly absorbed by plants, the disadvantages are fast volatilization, low utilization rate, less absorption by plants, and impact on the environment. Urea belongs to the amide nitrogen fertilizer, because it needs three-step transformation in the process of decomposition in the soil: the first step is to release urease from bacte...
