Magnesium is an activator for various enzymes, such as phosphatases, creatine kinase, hexokinase, and carboxylases. Magnesium is also an essential element for the structure of macromolecules like DNA, RNA, and ribosomes. It is a crucial element for maintaining normal nerve and muscle function. Deviations of serum magnesium concentration from the normal range are associated with certain kidney and endocrine diseases.

Blood phosphorus primarily refers to inorganic phosphorus in the blood, existing in the form of inorganic phosphate salts. The concentrations of calcium and phosphorus in plasma are closely related. When expressed in mg/dL, their product ([Ca]×[P]) ranges from 30 to 40. When ([Ca]×[P]) > 40, calcium and phosphorus tend to deposit as bone salts in bone tissue; if ([Ca]×[P]) < 35, bone calcification is hindered, potentially leading to bone salt dissolution and affecting bone formation. The relative stability of blood calcium and phosphorus levels depends on the balance between calcium/phosphorus absorption and excretion, and the metabolic balance between calcification and decalcification. This balance is regulated by hormones such as Vitamin D3, parathyroid hormone, and calcitonin.

The hydrolysis reaction of Soil-Fluorescein Diacetate (S-FDA) effectively reflects changes in microbial activity and soil quality, as well as the transformation of organic matter in ecosystems. It is one of the important biological indicators in soil quality research.

Ammonium nitrogen in soil can be adsorbed by soil colloids, existing as exchangeable ammonium nitrogen fertilizer, or dissolved in soil solution. It can be directly absorbed and utilized by plants, belonging to fast-acting nitrogen.
