20-7-20

Acid Formula

20-7-20 Acid Formula is designed to give heavy acidifying action and is ideal for nursery and landscape crops that thrive in acidic soil. This blend contains no Urea and a lower level of Phosphate. A few applications should bring the pH down to desirable levels and care should be taken not to drop the pH below optimum growing range.
