The function of bio-organic fertilizer and matters needing attention

Farmers can not do without fertilizer when planting land. Every time they grow vigorously, they often encounter improper fertilization. With the increasing pollution of chemical fertilizer, many farmers will choose pollution-free fertilizer. Biological organic fertilizer is a more and more widely used, it is derived from animal and plant residues and after treatment, compound fertilizer. So what does it do? How do I use it? Let's take a look at it together with Xiaobian.

1. Biological organic fertilizer

1. Improve soil and improve soil fertility

The function of biological organic fertilizer can improve soil fertility and promote crop growth, while farm manure and refined organic fertilizer are formed by natural fermentation and do not have this effect.

2. Promote plant growth

Compared with microbial inoculants, bio-organic fertilizer contains both functional and organic matter. In addition to improving the soil, it is the living environment of functional bacteria. It is easy to colonize and play a role after being applied to the soil. The biological fertilizer only contains functional bacteria, and the functional bacteria are not suitable for all soils and cannot survive. In addition, the price of biological organic fertilizer is cheaper than that of biological fertilizer.

3. Improve disease resistance

Bio-organic fertilizer has comprehensive nutrient elements, long-term use can effectively improve soil, balance rhizosphere micro-ecological environment, improve crop pest resistance, and improve crop yield and quality.

4. Improve fertilizer utilization rate

Biological organic fertilizer can release nutrients in the soil, improve soil fertility, greatly reduce the amount of chemical fertilizer and organic fertilizer, but can not completely replace chemical fertilizer and organic fertilizer, its fertility is limited, so it needs chemical fertilizer and organic fertilizer.

5. Degradation of pesticides

Bioorganic fertilizer can degrade pesticides, repair soil and reduce pollution, which is of great significance to realize resource-saving and environment-friendly society, and is an inevitable choice to realize sustainable agricultural development.

II. How to use it

The method of using bio-organic fertilizer is different in different situations, such as seedbed or broadcast crops, the use of bio-organic fertilizer is spreading; and transplanted crops are generally applied by hole or furrow; the most topdressing application is open ring or "well" shaped furrow application. In addition, the depth and amount of fertilization should be determined according to the crops, and after fertilization, new soil should be covered and watering should be kept moist.

III. Precautions

When using bio-organic fertilizer, it is best to use the soil pH value of 5.5-8.5. If the pH value is too low or too high, it needs to be adjusted properly. After applying bio-organic fertilizer, it cannot be used at the same time as fungicide, physiological acid and physiological alkaline fertilizer. If it cannot be avoided, it should be separated by more than 48 hours. After opening the package, it should not be stored for a long time. It is best to use it at one time to avoid reducing the fertilizer efficiency. Fertilizer should be stored in a place away from light and rain, mixed with chemical fertilizer, used immediately, and mixed well with soil.

The above is an introduction to the role and precautions of bio-organic fertilizer. I hope it can help you. If you want to know more about it, please pay attention to us.
