What are the effects and precautions of bio-organic fertilizer?
Farmers cannot do without fertilizer when farming. Whenever crops grow vigorously, improper fertilization often occurs, and as chemical fertilizer pollution becomes more and more serious, many farmers choose pollution-free fertilizers. Bio-organic fertilizer is one that is being used more and more widely; it is a fertilizer made from animal and plant residues as its source, processed and compounded. So what effects does it have? How should it be used? Let's take a look together.
I. Effects of bio-organic fertilizer
1. Improve soil and increase water and fertilizer retention capacity
The functional bacteria in bio-organic fertilizer can improve soil fertility and promote crop growth, while farmyard 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 bacteria and organic matter. In addition to improving soil, it is itself the living environment for functional bacteria, and after being applied to the soil it is very easy for them to colonize and take effect. Microbial fertilizer, however, only contains functional bacteria, and the functional bacteria in it are not suitable for all soils and cannot survive. In addition, bio-organic fertilizer is cheaper than microbial fertilizer.
3. Improve disease resistance
Bio-organic fertilizer has comprehensive nutrient elements. Long-term use can effectively improve the soil, balance the rhizosphere microecological environment, improve the crop's resistance to pests and diseases, and increase crop yield and quality.
4. Improve fertilizer utilization rate
Bio-organic fertilizer can release nutrient elements in the soil and improve soil fertility, greatly reducing the application amount of chemical fertilizer and organic fertilizer. However, it cannot completely replace chemical fertilizer and organic fertilizer; its fertility is limited, so chemical fertilizer and organic fertilizer are needed.
5. Degrade pesticides
Bio-organic fertilizer can degrade pesticides, repair soil, and reduce pollution. It is of great significance to building a resource-saving and environment-friendly society, and is an inevitable choice for achieving sustainable agricultural development.
II. How to use it
The method of using bio-organic fertilizer differs depending on the situation. For example, for seedbeds or broadcast-sown crops, bio-organic fertilizer is applied by broadcasting; for transplanted crops, it is generally applied in holes or furrows; when used as topdressing, it is applied in ring-shaped or "well"-shaped furrows. In addition, the fertilization depth and application amount should be determined according to the crop, and after fertilization, new soil should be covered and water should be added to maintain moisture.
III. Precautions
When using bio-organic fertilizer, a soil pH of 5.5-8.5 is best. If the acidity or alkalinity is too low or too high, it needs to be properly adjusted before application. Bio-organic fertilizer cannot be used at the same time as fungicides, physiologically acidic fertilizers, or physiologically alkaline fertilizers. If this cannot be avoided, there should be an interval of more than 48 hours. After opening the package, it should not be stored for a long time; it is best to use it all at once to avoid reducing fertilizer efficiency. The fertilizer should be stored in a place protected from light and rain. When mixed with chemical fertilizer, it should be prepared and used immediately, and fully mixed with soil.
