The soil pH is the pH of the soil and "pH" means "potential hydrogen." The effectiveness of the fertilizer directly affects the pH of the soil. The pH of the soil is too high or too low, some nutrients become insoluble, and the effectiveness is reduced, so that it cannot be well absorbed by the root system. The range of pH is from 0 to 14, which is acidic, neutral and alkaline according to the pH from small to large. The pH value of 7 indicates that the soil is neutral, less than 7 is acidic, and more than 7 is alkaline.

In fact, the pH of the soil represents the negative logarithm of the concentration of hydrogen ions in the soil solution. In other words, when the pH value differs by one unit, the concentration of hydrogen ions in the soil solution differs by 10 times. The concentration of hydrogen ions in a soil solution with a pH of 5 is 10 times greater than that of a solution with a pH of 6 and 100 times greater than the concentration of hydrogen ions in a solution with a pH of 7, making it more acidic, so it is decided Consider the possible consequences when raising or lowering soil pH. Other factors, such as the type of media, organic properties, etc. will also have a certain impact on the pH value. Fertilizer and rain also affect the pH value. Other factors include soil texture structure, organic matter type, and trace elements in the soil. Although their effects are small, they all have different degrees of pH changes.

Agricultural lime is generally used to increase the pH of the soil, while sulfur can be used to lower the pH, but usual watering and fertilization can change the pH of the soil solution more quickly. Plants need to maintain a certain pH range before they can grow normally. Most plants can maintain good growth in the range of 6.0 to 7.0, but rhododendron, gardenia, camellia and other plants need acidic soil, and the pH is maintained at 4.5 to 6.0. Only about normal growth.

Therefore, understanding the growth characteristics of the cultivated plants in the production (such as the appropriate pH, nutrient requirements, etc.) is a prerequisite to ensure success.

Traction of the spine, known as Cervical Traction, is a popular treatment for neck pain and related injuries. Essentially, cervical traction pulls your head away from your neck to create expansion and eliminate compression. It`s considered to be an alternative treatment for neck pain, helping people avoid the need for medication or surgeries. It can be used as part of a physical therapy treatment or on your own at home.

Cervical traction devices treat different types and causes of neck pain, tension, and tightness. Cervical traction helps to relax the muscles, which can significantly relieve pain and stiffness while increasing flexibility. It`s also used to treat and flatten bulging or herniated disks. It can alleviate pain from joints, sprains, and spasms. It`s also used to treat neck injuries, pinched nerves, and cervical spondylosis.
