Blending Charts
for Adding Nulex® Liquid Zinc
to 10-34-0 and 7-21-7
COMMENTS:
- Use the following charts to determine the correct ratio of Nulex Liquid Zinc to
products like 10-34-0 and 7-21-7.
- The charts are based on 20-to-1, phosphorus to zinc ratio.
- The second column (Minimum 10-34-0/7-21-7 Gallons per Acre) is the minimum amount of
10-34-0 or 7-21-7 that must be applied per acre to sequester, or hold, the given amount of
Nulex in solution. Nulex and ammonium polyphosphates, such as 10-34-0 or 7-21-7, are very
compatible but ammonium polyphosphates only have the ability to hold a given amount of
zinc metal. This given amount corresponds to a 20-parts phosphorus to a 1-part zinc ratio.
If this ratio exceeds 20-to-1, a zinc compound will precipitate from the solution.
EXAMPLE:
On the 10-34-0 Blend Chart locate 0.5 under the "Pounds of Actual Zinc per
Acre." The 0.5 represents the amount of actual zinc you have determined your field
needs. Move one column to the right. The "Minimum 10-34-0 Gallons per Acre" you
must use is 3 gallons per acre–although you may use more 10-34-0. At least that
amount will hold Nulex in solution. If you use Nulex 10%; 0.49 gallons, or 2.0 quarts, per
acre is needed. Since Nulex 10% weighs 10.2 pounds per gallon, you would use 5 pounds of
Nulex.
QUICK STATS:
- 10-34-0 weighs 11.7 lbs/gallon. Each gallon contains 3.98 pounds of actual
phosphorus.
- 7-21-7 weighs 11.2 lbs/gallon. Each gallon contains 2.35 pounds of actual
phosphorus.
- Nulex 10% weighs 10.2 lbs/gallon. Each gallon contains 1.02 pounds of actual zinc.
- Nulex 15% weighs 11.2 lbs/gallon. Each gallon contains 1.68 pounds of actual zinc.
- Nulex 20% weighs 11.4 lbs/gallon. Each gallon contains 2.28 pounds of actual zinc.
