John & Bob's Nourish Biosol Fertilizer 6-1-1 is able to be certified organic as well as certified non-GMO, while remaining the best and most effective fertilizer we have ever used. Its beneficial biomass enhances soil health and microbial life. This unique slow release nutrient formulation provides vital plant nutrients throughout the entire growing season due to the fermented organic material. There is an increased effect on the formation of humus, root mass and the living microbial biomass in the soils. Promoting a healthy balance of microbial life ensures long-term plant color, yield and plant health. This results in far lower concentrations of nitrates in ground water than synthetic fertilizers. Nourish-Biosol will not burn and remains safe to be used around pets and children.
