Reasons for soil acidification: precipitation or watering is large and concentrated; long-term large-scale application of chemical fertilizers, most of which are currently acid fertilizers. Solution: Pay attention to the application of high-quality organic fertilizers, increase the content of organic matter in the soil, and fertilize scientifically. At the same time, pay attention to the application of microbial fertilizers and soil conditioners, increase the number of beneficial microorganisms in the soil, and maintain the fertility of the soil. The reason for the imbalance of soil nutrient ratio: Crop growth requires 17 essential nutrient elements, and in daily management, only the application of nitrogen, phosphorus, and potassium fertilizers is emphasized, and the middle and trace element fertilizers are ignored, resulting in the exhaustion of trace elements in the soil and the accumulation of large elements. Solution: apply more organic fertilizer. Organic fertilizer can increase soil humus, is conducive to the formation of aggregate structure, improves soil aeration, water permeability and nutrient conditions, and can decompose and release some solidified nutrients to the soil. Apply medium and trace element fertilizers. Unreasonable use of chemical fertilizers will lead to the lack of trace elements, which must be supplemented in time and accurately to achieve a good harvest. Pay attention to extra-root top dressing (foliar fertilizer). Foliar fertilizer can replenish the missing elements to plants in time.

Hepatitis can damage the liver, affect liver function, and over time lead to complications such as cirrhosis, which is severe scarring of the liver, and liver cancer.
Hepatitis E: Hepatitis E is caused by the hepatitis E virus (HEV). Hepatitis E is spread through ingesting small amounts of the virus, often through drinking contaminated water and from animals to people when consuming undercooked foods like pork or wild game. HEV causes an acute infection that doesn`t require treatment.

There are many types of hepatitis, with both infectious and noninfectious causes. Infectious hepatitis is caused by an infection with a virus, bacteria, fungus, or parasites. The most common type of infectious hepatitis is viral hepatitis, which describes hepatitis caused by an infection with one of several hepatitis viruses. Viral hepatitis includes five main types:
Hepatitis A: Hepatitis A is caused by the hepatitis A virus (HAV). This type of hepatitis is spread easily through contact with stool or blood of an infected person. This can occur through contaminated water and food, sexual contact, or shared intravenous needles. The hepatitis A virus causes acute infections that are often mild, typically resolving without treatment within several weeks. Highly effective vaccines are available to prevent hepatitis A.
Hepatitis B: Hepatitis B is caused by the hepatitis B virus (HBV). Hepatitis B can be spread through contact with an infected person`s blood or certain other body fluids, including transmission from a mother to her baby. This virus can cause either acute or chronic infections. Highly effective hepatitis B vaccination is available to prevent infection.
Hepatitis C: Hepatitis C is caused by the hepatitis C virus (HCV). The hepatitis C virus is spread through exposure to the blood of a person with this infection, often through the use of injectable drugs and during birth to a mother with an HCV infection. This virus can cause both acute and chronic infections. Currently, there is no vaccine to prevent hepatitis C; however, it is treatable.
Hepatitis D: Also known as delta hepatitis, hepatitis D is caused by the hepatitis D virus (HDV). This virus is unique in that it only infects people who already have the hepatitis B virus. HDV is spread through the blood or other body fluid of an infected person, most often from sharing needles and unprotected sex with a person who has this infection. Hepatitis D can be either acute or chronic. The vaccine for hepatitis B can prevent hepatitis D because only those infected with hepatitis B can contract HDV.
