For thousands of years, people have added food wastes and charcoal to build rich soil in the Amazon.
We have improved on that concept by composting a broad spectrum of ingredients and feeding it to worms that digest and excrete rich castings with a broad spectrum of beneficial microorganisms.
Then, we blend the microorganisms with finely graded hardwood biochar, which is horticultural charcoal. The biochar remains in the soil for hundreds of years, attracting microbes and keeping them in the root zone of your plants.
Plant roots provide exudates to the microbes in exchange for nutrients in a natural balance as they need them.
You can use BioPreta dry or in a liquid organic plant food form.
