Doggett Tree Fertilizer 32 - 7 - 7 is a highly effective fertilizer with high Ureaform content. It does not dissolve immediately and remains suspended instead, making it perfect for use of professional arborists. Offers low salt index so it has a lesser risk of crop injury especially during periods of drought. The Doggett Tree Fertilizer 32 - 7 - 7 is a slow-release fertilizer that releases nitrogen during the entire growing season. Bacteria convert the portion of the nitrogen that is easiest to dissolve so 1/3 is released during the first six weeks then another 1/3 after six weeks to 3 months and the last 1/3 after 12 months. Any nitrogen that was not released can carry forward for the next season. It is an excellent blend of Ureaform and selected raw materials that deliver optimum performance. An injectable tree fertilizer that is easy and convenient to apply. This fertilizer is best injected 4 to 6 inches deep using an injector with 150 to 200 PSI. It is highly suggested to apply it on the trunk of the tree extending beyond the dripline with 2 1/2 feet apart. For best results, inject 150 gallons of solution over 2,000 square feet. Packaged in a plastic bag with 30 pounds of fertilizer.

For use in
Soil injection should be 4 to 6 inches deep using an injector probe at 150 to 200 PSI. The injection should begin out from the trunk and be spaced 2 ½ ft. apart, injecting on a grid extending beyond the dripline. Apply 150 gallons to each 2,000 sq. ft.
Yes, if used as directed on the label.
15.00 x 3.00 x 18.50 inches.
150 gallons cover 2,000 square feet.
Releases nitrogen over the entire growing season and any not released during the first season will carry over to the following year.
When we do not wish to promote soft growth late in the season but wish to feed the tree for a good wintering and a strong start in the spring, we suggest that you use our DOGGETT TREE FERTILIZER FALL FORMULATION 12-24-24, with available phosphate and potassium.

90% of feeder roots are in the top 12 inches of soil with the majority in the first 6 inches. They start well out from the trunk and extend well beyond the dripline in most cases. This is the area to be injected with DOGGETT TREE FERTILIZER. Soil injection should be 4 to 6 inches deep using an injector probe at 150 to 200 PSI.
The injection should begin out from the trunk and be spaced 2 ½ ft. apart, injecting on a grid extending beyond the dripline. Apply 150 gallons to each 2,000 sq. ft. Following the grid method outlined, you should inject approximately 1/ 2 gallon of fertilizer solution at each point. Based on the 2 ½ ft. spacing, this will apply 150 gallons of solution over 2000 feet which contains 7.2 pounds of N or 3.6 pounds N per 1000 square feet.
To Calibrate your particular rig and its operator, we suggest you find out how long it takes to inject 1/2 gallon of solution into a bucket. This will probably take 2 to 4 seconds. Count off the seconds and use this same count and cadence while injecting the probe at each point in the soil.
TRUNK RATEOF APPLICATION
Use dilution rate as shown in table (15 lbs. in 100 gallons of water). Apply the solution at the rate of 5 gallons per inch of trunk diameter.
CROWN SPREAD TECHNIQUE
(concentric circles) Inject 150 gallons over 2,000 square feet. Space injection points at 2 ½ sq. ft. intervals, starting well out from the trunk and extending well beyond the dripline in unencumbered soils.
FIVE GALLONS OF FERTILIZER SOLUTION PER INCH OF TRUNK DIAMETER
Example: Tree Trunk 12? times 5gallons = 60 gallons of solution.
