Precautions for the application of bacterial fertilizer. Bacterial fertilizer, which is also called biological fertilizer, does not contain the nutrients needed for plant growth and development. It is a new type of pollution-free compound biological fertilizer developed through scientific formula and combined processing. There are a lot of microorganisms in the soil, mainly through the life activities of microorganisms to improve the nutritional conditions of crops.

What are the common precautions for applying bacterial fertilizer in farmland?
1. According to local conditions, it is not advisable to apply biological bacterial fertilizer to soil and rusty paddy fields with high sulfur content, because sulfur can kill biological bacteria. For the paddy fields that are turned with mash, bacteria fertilizer is generally not spread, and the effect of spraying is more obvious. Bacterial fertilizer is not suitable for farmland under high temperature, low temperature and drought conditions due to temperature conditions. The best temperature for applying bacterial fertilizer is 25-37℃, and the application effect is poor when it is lower than 5℃ or higher than 45℃. When the soil moisture content is between 60-70%, the fertilizer effect of bacterial fertilizer is better. The drum granulation
can be used for the production of bacterial fertilizer. Bacterial fertilizer should not be mixed with fungicides, insecticides, herbicides, sulfur-containing fertilizers (such as potassium sulfate, etc.), and straw ash, etc., because these drugs and fertilizers can easily kill biological bacteria. If you must use the above-mentioned medicines and fertilizers, you can apply bacterial fertilizer first, and then spray the medicines and weeds after 48 hours. When using bacterial fertilizer for seed dressing, do not mix seeds mixed with bacterial fertilizer and seeds mixed with fungicides.
2. In addition, it is necessary to prevent the mixed use of bacterial fertilizers with immature farmyard manure. For the fields that have been applied with chemical fertilizers for many years, chemical fertilizers and organic fertilizers cannot be greatly reduced when applying biological bacterial fertilizers. Because crops are dependent on chemical fertilizers, the use of biological bacterial fertilizers instead of nitrogen fertilizers makes crops unable to adapt. The replacement amount of bacterial fertilizer should be gradually increased, replacing 30%, 40% and 60% of nitrogen fertilizer in the second and third years respectively. Phosphorus and potash fertilizers can only make up, not reduce. Biological fertilizer is not a quick-acting fertilizer according to time conditions. It is effective when applied 7-10 days before the critical period of crop nutrition and the period of nutrient absorption.
