Plantex® 24-8-16 Foliage water soluble fertilizer was formulated according to the University of Florida’s recommendations for foliage crops suggesting a 3-1-2 ratio fertilizer. Urea is used as the principle source of nitrogen since research has indicated that the majority of foliage crops can readily utilize it.
Plantex 21-7-7 water soluble fertilizer 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 21-5-20 High Nitrate Low P water soluble fertilizer is effective in soilless media, this is used as a general feed and forms the base for many fertilizer programs. This urea free and high nitrate, balanced growth formulation, with complete micronutrient availability, includes magnesium and extra iron to provide optimum plant nutrition.
Plantex 20-8-20 Forestry High Nitrate water soluble fertilizer Rapid vegetative growth of forest seedlings occurs between the 4th and 16th weeks of growth. Plantex 20-8-20 should be used on a constant feed basis to encourage good top growth. This formulation contains four times more iron than most Plantex fertilizers, lower phosphorus and added magnesium. It should be used for the majority of the growing season, once seedlings have a well established root system.
Plantex 20-5-30 water soluble fertilizer is recommended for summer feeding of roses, geraniums and other ornamentals. Greenhouse tomatoes and cucumbers grown in soil respond well to this formula when used alone or in combination with potassium nitrate. This high potassium fertilizer is ideal for use when plants are maturing and blooming. It allows the plants to establish heavier, thick-walled cells which results in efficient water utilization. Since the potential acidity is very low, Plantex 20-5-30 will exhibit minimal acidifying activity in the soil. It is particularly useful where a change in soil pH is undesirable.
Plantex 20-2-20 water soluble fertilizer helps keep the pH low and contributes very little phosphorus. This formulation in combination with Plantex 14-0-14 is ideal for plugs and bedding plants. Plantex 20-2-20, because of its high potential acidity is very useful in maintaining an ideal pH balance in plug media. Plantex 20-2-20 can also be used for production of blue hydrangeas and easter lilies when excess phosphorus is not required.
Plantex 20-20-20 water soluble fertilizer is very effective on all types of plants. Its balanced formula may be used whenever a more general formulation is required. Its high percentage of ammoniacal and urea nitrogen will provide rapid green up and leaf expansion while the balanced phosphorous and potassium will encourage root and shoot growth.
Plantex 20-10-20 water soluble fertilizer has 60% of its nitrogen in the nitrate form, and a complete minor elements package including a higher level of molybdenum, as required for soilless mixes. This is an ideal formulation for use in low light conditions.
Also available in a Lite formulation with half the amount of micronutrients.
Plantex 18-6-20 water soluble fertilizer contains over 60% of the nitrogen in the nitrate form, a high level of magnesium, an increased level of molybdenum, a low boron level and chelated micronutrients.
