Fertilizer

It is used to prepare ferrous ion standard solution in analytical chemistry. It is also used for printing type plate coating to prolong the service life of type plate. It is also used in medicine, electroplating, etc.

It is mainly used in agriculture. It can be used as chemical fertilizer, herbicide and insecticide, treat wheat, fruit trees, potatoes, corn, vegetables, flowers and trees, prevent orchard pests and rot of fruit trees, and eradicate mosses and lichens of tree stems.

Disodium octaborate tetrahydrate, an alkaline salt, is produced in two forms. One is a clear, liquid concentrate, which can be mistaken for corn syrup if repackaged and not properly labeled or it is packaged as a white, odorless, powdered chemical substance that is not flammable, combustible, or explosive and has low acute oral and dermal toxicity. This salt, which is commonly confused with boric acid, is used as an insecticide and is commonly sold in liquid or powder form. It is also effective against fungi and algae. It has an infinite shelf life and is not affected by temperature. "Bora-Care" is the liquid form suitable for use in a sprayer. The powdered brands are "Tim-Bor," "Borathor," "Termite Prufe" or "Board Defense" as sold in the United States. This chemical is also a flame-retardant. In the liquid form, it is commonly diluted and sprayed on wood surfaces to kill termites, powder post beetles, carpenter ants, fungi and algae. It is also available as pellets for embedding in structural wood. This alkaline salt is not to be confused with boric acid (an acidic chemical) or the laundry detergent additive used for stains. In common use as a termite control or for termite prevention, the liquid concentrate is used at a ratio of 1:1 with water. The advantages to this chemical over conventional pest control treatment is that it is non-carcinogenic and has a low toxicity to humans and pets. It is also odorless and proper application lasts for the lifetime of the wood. Repeat treatment is not necessary. It is best used during new construction, however, it is more commonly used after the fact on homes originally treated with chemicals that have become inactive. It was shown to significantly reduce dust mite populations in the home when combined with regular vacuum cleaner use.

Humic acid is a complex mixture of natural organic polymer compounds with weak acidity, hydrophilicity, complexability, redox, ion exchange and physiological activity. It can be used as soil conditioner, plant growth stimulant, pesticide, fertilizer, herbicide, medicine, mud stabilizer and ion exchanger for oil drilling, battery plate, etc. Its sodium salt or ammonium salt is used as the binder of pulverized coal to make humic acid briquette.

It can be used in medicine and electrochemical grade as electrolyte.
