Biological Chitosan is a byproduct of shrimp and crab shells, which are then mixed with a specific bacteria to create a nitrogen-rich fertilizer. This fertilizer can be used in any type of soil and provides the soil with increased nitrogen, phosphate, and potassium. The nitrogen in the fertilizer will help promote healthy root growth, increase the overall yield of plants, and will help prevent fungal diseases. Biological Chitin is easy to use and can be mixed with any type of soil.
