Development of micronutrients for crop air application

摘要

Abstract: the invention refers to the use of an oil-containing micronutrient liquid component, including one or more particulate micronutrient sources that are basically insoluble in water, suspended in an oil-based liquid environment, so as to use the leaves for crop growth through an oil spraying system. The particle size of micronutrient source is basically between 0.1 and 100 mg.
