Matters needing attention in applying bio organic fertilizer

pubdate:2020-07-17

Bio organic fertilizer is a kind of fertilizer with the effect of both microbial fertilizer and organic fertilizer, which is composed of specific functional microorganisms and organic materials mainly from animal and plant residues and after harmless treatment and decomposition. What problems should be paid attention to when applying bio organic fertilizer?

1. Select qualified microbial fertilizer. The products with low quality, low effective viable count, high miscellaneous bacteria content or expired period can not be applied.

2. Reduce the microbial death in fertilizer as much as possible. Avoid direct sunlight on bacterial fertilizer, operate in a cool place during seed dressing, sow seeds in time after seed dressing, and cover soil immediately. General bacterial fertilizer can not be mixed with harmful pesticides and chemical fertilizers.

3. Suitable soil environment. When applied on acid soil, the soil acidity should be neutralized before application. When the soil is too dry, it should be irrigated in time. After the heavy rain, the field water should be removed in time to improve the soil permeability.

4. Promote the application of different microbial fertilizers according to local conditions. For example, Rhizobium fertilizer should be widely used in legume crops, and phosphorus and potassium solubilizing microbial fertilizer should be used in soil with high nutrient potential.

5. Avoid long-term use after opening the bag, and pay attention to sealed storage to avoid the loss of bacteria. If it is not used for a long time after opening the bag, others may invade into the bag, which will change the microbial flora in the fertilizer and affect its use effect.

6. Avoid using under high temperature and drought. Under the condition of high temperature and drought, the survival and reproduction of microorganisms in microbial fertilizer will be affected and can not play a good role. Therefore, it should be applied in the evening on cloudy or sunny days, combined with measures such as covering soil, covering manure and watering, so as to prevent microbial fertilizer from being exposed to direct sunlight or difficult to play its role due to lack of water.

7. Avoid mixed use with unripe farm manure. When mixed with uncooked organic fertilizer, it will kill microorganisms due to high temperature and affect the application of microbial fertilizer.

Bio organic fertilizer can not be mixed with chemical fertilizer at will, but the fertilizer efficiency of some chemical fertilizers and bio organic fertilizer will decrease, so we should pay attention to it.
