Plantex 21-7-7 has a very high potential acidity. If used in a continuous feeding program, the pH should be monitored to ensure that it does not go below the desired level. It is recommended for crops such as azaleas, rhododendrons and many evergreens requring acid soil conditions. When irrigation water has a high pH, Plantex 21-7-7 will help to overcome the effect of the bicarbonate ions in the media and gradually reduce the pH for better growth of bedding plants, pot crops, cut flowers, and nursery stock in containers and in the field.
Plantex 21-7-7 Acid has a very high acidifying potential. It can be utilized within a continuous fertilization program, provided that it is ensured that the pH does not go below the desired level.
*When the irrigation water has a high pH, it neutralizes the effect of the bicarbonate ions in the cultivation medium et reduces progressively the pH
*Plants loving acidic soils such as rhododendrons and many conifers
*The ammonium/urea is ideal for azaleas
