Q:The lack of three major inorganic salts can cause symptoms in the plant: Nitrogen: to promote cell division and growth, so that leaves grow lush. Lack of performance: plant thin and thin, leaves yellow, severe leaves were light brown.

Q:The difference between the ignition of inorganic salts and organic matter: Inorganic salts that inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, of which constant elements are iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8 species. If you pay attention to diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, the body can make the inorganic salt to maintain the normal level.

Q:After running the training is best to drink what drinks add inorganic salt: C100 ah

Q:Which minerals is richest source of Inorganic Salts ?: Minerals are inorganic salts - eg.potassium nitrate - absorbed by plants from soil - a good source of inorganic nitrogen and potassium.

Q:Why does inorganic salts affect chemical degradation of organic wastewater: Industrial organic waste water is highly toxic and stable pollutants, for such waste water is difficult to use conventional physical, chemical and biological methods. This paper summarizes the main processing technologies of biodegradable organic wastewater at home and abroad, including biological treatment, chemical treatment and physical treatment and various joint treatment processes. The methods or processes of various methods or processes are described.

Q:What are the physiological functions of inorganic salts: Maintain the life of cells and organisms

Q:What inorganic salts are needed for seeds?: Phosphate, nitrogen, magnesium, calcium, iron, copper, and boric acid

Q:What is the most important inorganic salt in plant growth?: The inorganic salts required by plants are nitrogen, phosphorus and potassium containing inorganic salts, and if any lack of plants will affect the normal growth of plants, nitrogen is a component of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll , Enzymes, vitamins, alkaloids and some hormones contain nitrogen. Nitrogen is also the basis of genetic material in all organisms, the most important protein, it is often in the center of metabolic activity.Now is to limit the growth of plants and the formation of the primary Factor. It also has a significant effect on improving the quality of the product.K2 is dissolved in the plant juice, and its main function is related to the metabolism of the plant.The content of phosphorus in the plant is second only to nitrogen and potassium, Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis, respiration, energy storage and delivery, cell division, cell enlargement and other processes in plants.

Q:Why inorganic salt waterproof coating does not apply to roof waterproofing: Inorganic salts waterproof coating to waterproof agent-based, and the roof may produce vibration or displacement, the general selection of waterproofing membrane and flexible waterproof coating.

Q:Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.: Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
