Mixing Instructions
Chart displays the amount of dry fertilizer (oz.) to add to each gallon of water to make a concentrated solution. Please check your injector setting before use.
Mixing Table
| Desired N Feed Rate | 1:15 | 1:100 | 1:200 | E.C. Value |
|---|---|---|---|---|
| 50 ppm | 0.68 | 4.50 | 9.00 | 0.37 |
| 100 ppm | 1.35 | 9.00 | 18.00 | 0.74 |
| 200 ppm | 2.70 | 18.00 | 36.00 | 1.48 |
Limit of Solubility = 7 lbs per gallon
Important Notes:
E.C. value is the best method to determine fertilizer strength. Fertilizer appearance may vary in color due to variation in raw material size and tracer dye distribution upon the particles in the bag. In solution, color will remain consistent.
For best results, use warm water to dissolve product. Jack's fertilizers are made with 100% soluble raw materials that will form a true solution. Some raw materials are slower to dissolve than others. Keep stock tank covered to reduce light and debris inputs.
