Liquid Fertilizer
Biota N15 is unique because it is the highest concentration liquid biological single 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 certified 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.

Application
CROP | APPLICATION |
Vegetables | Start for 5 to 6 weeks during development of the first roots. Use weekly during vegetative development, fruit formation and hydric stress. |
Cotton | First 5 weeks after planting. Weekly applications from just before bloom until the last bud has developed. |
Corn | Start for 5 to 6 weeks during development of the first roots. 3-4 applications every 7-15 days from bloom until the last bud has developed. |
Citrus and fruit trees | Start when the first leaves or buds form. Repeat every 7-15 days. |
Grapevine and olive | Every 7-15 days from bloom until fruit development. |
Ornamental | Start for 5-6 weeks during development of the first roots. Apply weekly, especially during bud formation. |
Potato | During development of tubers, especially in sandy soils and at the end of the vegetative stage. |
APPLICATION | DOSE | INDICATION |
