Crops such as cut flowers, container nursery stock and field grown vegetables respond well to this formula. It can be used for foliar feeding due to its very low salt index and high level of urea nitrogen. Use during periods of vegetative growth when plants have a high nitrogen requirement. Use to correct nitrogen deficiency where soil or tissue tests show low nitrogen.
Plant-Prod 24-10-20 is ideal for lowering the pH in the stock tank. It contains urea phosphate, which keeps drip lines clean and clear from plugging.
Plant-Prod 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, Plant-Prod 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.
Rapid vegetative growth of forest seedlings occurs between the 4th and 16th weeks of growth. Plant-Prod 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 Plant-Prod 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.
Plant-Prod 20-8-20 is an all purpose, higher nitrate fertilizer is ideal for plants grown in soilless media and forms the backbone of many greenhouse growers’ nutritional programs. Over 60% of the nitrogen is in the nitrate form, making it an ideal formulation for any time of the year, even during low light conditions. Use alone or in rotation with Plant-Prod 15-0-15 Cal Plus or Plant-Prod 14-0-14 Cal Mag to provide a balanced fertilizer program.

Plant-Prod 20-5-30 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, this fertilizer will exhibit minimal acidifying activity in the soil. It is particularly useful where a change in soil pH is undesirable.
Plant-Prod 20-2-20 helps keep the pH low and contributes very little phosphorus. This formulation in combination with Plant-Prod 14-0-14 is ideal for plugs and bedding plants. Plant-Prod 20-2-20, because of its high potential acidity is very useful in maintaining an ideal pH balance in plug media. Plant-Prod 20-2-20 can also be used for production of blue hydrangeas and easter lilies when excess phosphorus is not required.
Plant-Prod 20-20-20 is a general purpose 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.
Plant-Prod 20-10-20 fertilizer without colorant has been specially developed to meet the particular needs of professional interior designers.
Plant-Prod 20-10-20, 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.
