How to Properly Use Bio-Bacterial Fertilizers

  As we know, bacterial fertilizers contain microorganisms such as Bacillus subtilis. They should not be used under high-temperature conditions, as excessive heat will kill the beneficial bacteria. Once opened, the product should be used promptly and not stored long-term. Ensure ventilation and dry storage.

   For leguminous crops, rhizobium fertilizers are typically chosen as inoculants for nodulation and nitrogen fixation. Additionally, phosphate-solubilizing bacteria fertilizers can convert insoluble phosphorus in soil into available forms like orthophosphate and inorganic phosphorus, enhancing utilization rates and alleviating soil compaction.

   Avoid applying organic microbial fertilizers during summer or winter when temperatures are high or low, as this reduces live bacteria counts and diminishes fertilizer efficacy. Spring or autumn application yields optimal results. Organic microbial fertilizers work best as base fertilizer, seed fertilizer, or seedling fertilizer, applied as close to crop roots as possible. Cover with soil immediately after application to prevent direct sunlight exposure, which can kill beneficial microorganisms and reduce utilization rates.

   Avoid mixing microbial fertilizers with chemical fertilizers or fungicides, especially fungicides. Fungicides kill both harmful and beneficial microorganisms indiscriminately, thereby impairing fertilizer efficacy.

   Prevent mixing microbial fertilizers with uncomposted farmyard manure. During decomposition, farmyard manure undergoes fermentation that generates high temperatures, killing live microorganisms and reducing fertilizer effectiveness.
