Southern Ag 20-20-20 Soluble Fertilizer

Southern Ag 20-20-20 Soluble Fertilizer is the best way to keep all of your plants growing to their greatest potential. Easy application in mixing with water, Southern Ag 20-20-20 Soluble Fertilizer helps your lawn, your garden, trees, even your house plants grow. Just place 2 teaspoon in a gallon of water and you have the right mix to keep your plants growing against anything Mother Nature will throw at them.


SPRAY  APPLICATION:  On  Vegetables,  Tobacco, Ornamentals, House Plants, Shrubs and Trees.  Use 5 lbs. per 100 gallons of water (2 TBS. per gallon). Apply as a full volume spray. Repeat at 7 to 10 day intervals  as  needed.

DRENCH APPLICATION:  On plant beds and potted plants, use 2 lbs. per 100 gallons of water (2 tsp. per gallon).  Apply at the rate of 1 quart per square foot or 100 gallons per 400 square feet. Repeat treatment every 1-3 weeks as needed.

CONSTANT  FEED: Fertilizer applications with every watering (3 or more times per week). Use at the rate of 100-200 ppm nitrogen, 6 3/4 oz. to 13 1/2 oz. per 100 gallons. Water applications should be with approximately 1 to 2 quarts per square foot or 100 to 200 gallons per 400 square feet (4/10 - 8/10 in. of water). Where injector systems are used, the following table may be used to determine the  amount  of  fertilizer to use in concentrate tank. When constant feeding, it is often desirable to leach potted and benched  plants about once a week in order to avoid excessive fertilizer build up, particularly on the soil surface.

NOTE: Indicated rates are intended as a guide for initial applications. Experience with the particular crop and frequent soil testing are best guides to proper fertilization. (See chart)

NOTE: Do not apply with hose-end sprayers or injection ratio feeders without using a proper anti-backflow device.

LAWNS  AND  TURF  GRASS: May be used as a supplement to regular fertilization when quick response and greening are needed. Use at the rate of 1 lb. per 10 gallons of water per 1,000 square feet. Apply monthly or as needed.

TRANSPLANT SOLUTION: For use on tobacco, vegetables such as tomato, lettuce, cabbage, cauliflower, eggplant and peppers. In general, use 3 lbs. per 100 gallons of solution (1 1/2 tbsp. per gallon). Pour around plant using 1/2 to 1 pint of solution per plant. Some plants such as tobacco may be sensitive to excess amounts of fertilizer and it is best to use the low rate of 1 lb. per 100 gallons initially and check plant response. If experience dictates, up to the 3 lb. rate may be used. This material is compatible with most insecticides and fungicides which are not highly alkaline such as Bordeaux mixture or Lime.

If compatibility is not known, test on small area before use. Timing, method and rates of application, differences in plant varieties, growing conditions and other influencing factors are beyond the control of the seller. Buyer assumes all risks of use, storage or handling of this material not in strict accordance with the directions for use and precautionary Statements on this label.

VOLUME EQUIVALENTS: 1 LB. = 2 CUPS, 1/2 LB. = 1 CUP, 1 oz. by weight = 1 oz. by volume (2 TBS.)

    Thank you for your comments! Keep in mind that Southern Ag 20-20-20 is a soluble fertilizer, meaning it should always be diluted first and then applied as a liquid or spray, per the product label. We appreciate your feedback and your business!

QCan you give some details concerning linear foot? I will be mixing and using in drip irrigation.

AWe apologize but the product label for Southern Ag 20-20-20 Soluble Fertilizer does not give information regarding that type of application.  It does give instructions for a constant feed. 

Fertilizer applications with every watering (3 or more times per week). Use at the rate
of 100-200 ppm nitrogen, 6 3/4 oz. to 13 1/2 ozs. per 100 gallons. Water with approximately 1-2 quarts per square foot or 100-200 gallons per 400 square feet (4/10 - 8/10 in. of water). We would recommend contacting the manufacturer directly for advice on the use you intend.  Southern Ag can be reached at 941-722-3285.
