Keep ecological balance in the soil

Soil is a major source of diseases for vegetables and pepper. Therefore, fruit and pepper diseases are called " soil diseases ".

General characteristics of VSV populations in soil:

The majority of VSV (microorganisms) living in the soil are useful living organisms in the form of saprophytic, only a few are harmful, causing disease for plants to live in the manner of parasites (causing disease in plants) just saprophytic (living in the soil). The number of beneficial VSV populations in the soil is much more predominant than that of VSV.

- Most of the VSVs are useful to participate in the process of decomposing plant material into organic feed for plants and other VSV, they play a very important role in mineralization and nitrogen fixation. Easy to digest for plants, VSV also produces many kinds of enzymes, amino acids, vitamins, antibiotics . which are important food and self-defense weapons for plants. In addition, when soil microorganisms die, there will be a huge amount of food and very good quality for plants .

- Useful VSV plays an important role in soil improvement, making soil humus, structured, porous, aerobic, neutral pH, making water retention and feces of soil improved. . Thanks to VSV's activities, the life of the land is increased.

- Useful VSV helps plants absorb nutrients better.

- VSV has contributed to protecting plants, reducing the harmful effects of parasites causing plant diseases.

- It is useful to have a very large number of antagonistic microorganisms in VSV in order to prevent the development of VSV that can be harmful to plants .

Development conditions of beneficial VSV and pathogenic parasites in soil:

Useful VSV living conditions and pathogenic parasites in the soil are very different, to the contrary.

- Useful VSV and antagonistic microorganisms thrive in conditions of soil rich in humus, no toxins such as pesticide residues in soil, neutral pH, soil structure, aerobic, not waterlogged. Thus, the useful living conditions of VSV and antagonistic microorganisms are very suitable for the living requirements of plants.

- Conversely, harmful microorganisms cause disease, they prefer to grow in acidic, watery, anaerobic conditions of humus, soils with a lot of pesticide residues do not affect the lives of VSV causing disease .

From those beneficial and harmful characteristics of VSV, we must be very careful in all the impacts on soil and crops such as cultivation, fertilization, use of plant protection facilities .

How do people impact VSV's life and land?

- The practice of cultivating land, plowing and removing all the plants from the field every year has caused the soil to be washed away, degenerated, soil is poor and nutritious, not suitable for the life of VSV.

- The reverse side of chemical fertilizers, especially nitrogen fertilizer products from petrochemical industry, has killed so much VSV is useful in the soil. Moreover, chemical fertilizers do not only contribute to enrichment but also kill VSV and remove all organic matter in the soil.

- In the long run, the effectiveness of chemical drugs is huge, they kill pests and, to some extent, protect plants for productivity. However, the chemical also kills VSV more effectively in the soil than VSV is harmful, especially the methods of steaming or irrigating chemical plants to the root of the disease to kill nematodes, fungi and pests .
