Compound fertilizer containing minor metallic element

Abstract

The invention discloses a compound fertilizer containing trace metallic elements. The compound fertilizer consists of 10.4 to 14.6 percent of blue vitriod, 7.1 to 10 percent of zinc sulphate mono, 17.7 to 21 percent of manganese sulfate monohydrate, 38.3 to 41.7 percent of ferrous sulfate monohydrate, 2.5 to 4.4 percent of magnesia and urea. The compound fertilizer is granular product and the grain diameter is controlled between 2 and 4 mm. The compound fertilizer can simplify operation sequence of fertilizer application, save the cost, has small harm to operating personnel and is favorable for the absorption of plants.

Description

technical field [0001] The invention relates to an inorganic fertilizer, in particular to an inorganic compound fertilizer containing trace metal elements. Background technique [0002] The human body cannot lack trace elements, such as copper, zinc, manganese, iron, etc. These trace elements are absorbed by animals and plants and then transferred to the human body after being eaten by humans. Such as milk, goat milk, beef, mutton, grains and their products, etc. The current compound fertilizers exist in different components of nitrogen, phosphorus and potassium, and do not contain trace elements. Trace elements such as copper, zinc, manganese, and iron are single components of copper sulfate, zinc sulfate, manganese sulfate, and ferrous sulfate, which are separately sown into the soil as required. They are all in the form of dry powder, which is easy to cause dust when spreading, and it is easy to cause damage to the respiratory tract of operators after inhalation, which ...

AI Technical Summary

Problems solved by technology

Trace elements such as copper, zinc, manganese, and iron are single components of copper sulfate, zinc sulfate, manganese sulfate, and ferrous sulfate, which are separately sown into the soil as required. They are all in the form of dry powder, which is easy to cause dust when spreading, and it is easy to cause damage to the respiratory tract of operators after inhalation, which is not only not conducive to environmental protection, but also easy to cause harm to the health of workers; Unbalanced absorption of plant nutrients, resulting in waste of fertilizers
