MONTEREY PERC-O-LATE PLUS is specially designed for use on western soils. MONTEREY PERC-O-LATE PLUS increases water penetration by increasing the rate at which water soaks into the soil, meaning greater water efficiency and less waste of water. MONTEREY PERC-O-LATE PLUS includes nitrogen and important trace elements (iron, zinc, manganese) which are in chelated form to facilitate availability to the plant.
