Biota N15

Biota N15 is unique because it is the highest concentration liquid organic single nutrient fertilizer on the market. Due to the unique production process, the nutrients are 100% present in solution and can therefore be taken up directly by the plant (50% in 8 to 12 minutes). It can be used as a quick source of nitrogen, during maximum vegetative development and to recover from nitrogen deficiency. The product is fully made from plant-based materials and approved for use in organic agri- and horticulture. The ingredients are partly sourced from agricultural waste. Due to the natural origin the nutrient content may vary.

Use as a supplement to nitrogen in the soil or as a replacement when the soil has at least 3% organic matter content. Repeated applications of Azotobacter nitrogen fixating bacteria can be reduced by using Biota N15.
