What Is Trace Element Fertilizer?

Trace element fertilizers refer to fertilizers containing trace element nutrients, which can be simple compounds containing one trace element, or compound fertilizers and mixed fertilizers containing a variety of trace and macronutrient elements.

Trace element fertilizers are mainly inorganic salts or oxides. Some minerals and metallurgical by-products or wastes can often be used as raw materials for trace element fertilizers. There are two types of fertilizer application methods: soil application and foliar spray application.
