YIELDBOOST Microbes is a high concentration of nitrogen fixing microorganisms that use carbon from the ground and the air to feed crops and in essense "compost" the soil to not only make nutrients more available to the plant but also aerate or loosen the ground to enhance water penetration and holding. High concentration means we add trillions of beneficial microorganisms per acre. Just add water. To activate these highly soluble  mirobes we recomend adding them to a 20 or 30 gal solution of water, liquid fertilizer, or any pestiside application.
