Oxygen is a life-line for all living organisms and is required by all plants throughout their life cycle for optimum growth. Oxy-Cal is a timed release supply of oxygen and calcium for the soil. It increases the microbial activity to provide a strong, disease-resistant growth medium. This enables the plants to better absorb and use the available nutrients and water.
