Biosol is the by-product of the penicillin fermentation manufacturing process: it’s a natural slow release organic fertilizer that is ideal for all types of planting. Providing several benefits that cannot be provided by other fertilizers. Biosol builds humus, feed soil microbes, feeds mycorrhizae and supplies natural nutrients to plants. Slow release nutrients promote plant growth while deterring weed growth. Biosol unlocks nutrients that are tied up in soils, and has proven and award-winning results in harsh conditions with little or no topsoil.


During the manufacture of penicillin, a fungal biomass (mycelium) is obtained by the
fermentation of raw materials such as: soybean meal, cottonseed meal, sucrose, lactose, trace elements
and vitamins under constant sterile conditions. The fungus strain used is Penicillium Chrysogenum.
After the penicillin is removed, the remaining biomass is dried at 110° to 130° C for 3 to 4 hours.
During this process the residual antibiotic is eliminated and the moisture is reduced by 3 to 6%.

Biosol is listed with OMRI and approved for organic farming.
Biosol is a fermented plant based organic fertilizer, sterilized and free of weed seeds.

Biosol’s 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 and plant health. This results in far lower concentrations of nitrates or phosphorous in
ground water than mineral fertilizers. Biosol will not burn seed or vegetation.

Biosol Forte is used for the following qualities:
  • Enriches soil with quality nutrients.
  • Stimulates micro-organism activity in the soil.
  • Improves plant health (chlorosis, stem disease, blossom drop).
  • Increases crop yields.
  • Increases the sugar content (content is expressed as degree Oechsle, Brix, or Balling).
  • It promotes quality ripening of fruits and vegetables.
