NitroSR: Extend Nitrogen Release Over Time
NitroSR is a slow release foliar fertilizer that derives its slow–release properties from methylene urease (estimated release pattern is 10–14 days.) NitroSR can be used on a broad spectrum of field, fruit, vegetable, and ornamental plants. Contact should be avoided with strong acids or aluminum, mild steel, and brass. One gallon of this product contains 0.045 pounds of elemental Boron and 2.45 pounds of Nitrogen. 25% of the Nitrogen in this product is slow–release.
Use Rates
NitroSR can be used for ground and aerial applications.

- Soybeans: 1–3 gal/acre at V6 to R3 as a Nitrogen supplement.
- Cereal Grains: 1–3 gal/acre from stage 2 to stage 8 as a Nitrogen supplement. 1–2 gal/acre at stages 10.1–10.5.
- Forage Crops and Pastures: 4–6 qt/acre after each cutting when sufficient foliage is present.
- Tobacco: 6–10 qt/acre from plant bed stage through maturity as needed to maintain crop growth and quality.

- Tomatoes: 4–6 qt/acre at full bloom and repeat every 10–14 days until near harvest.
Fruits
- Apples: 4–6 qt/acre prior to fruit set or post-harvest.
- Cantaloupes: 6–10 qt/acre at early flowering and repeat 7–10 days later.
- Cranberries: 4–6 qts/acre at hook stage and repeat after fruit set.
- Grapes: 2–4 qt/acre prior to fruit set.
- Peaches/Nectarines: 6–10 qt/acre prior to fruit set.
- Pears: 4–6 qt/acre prior to fruit set or post-harvest.
- Strawberries: 2–3 qt/acre at early flowering and repeat every 14 days through harvest. Begin fall applications when new growth reaches 3 inches.
- Watermelons: 6–10 qt/acre at early flowering and repeat 7–10 days later.
Commercial Christmas Trees, Ornamentals & Nursery Stock
- Apply 4–10 qts/acre when sufficient foliage is present. NitroSR has been used undiluted on select ornamentals and nursery stock. Due to differences among plant species, apply to a limited number of plants first and monitor for one week before wider use.
Other Crops
- 4–6 qt/acre when sufficient foliage is present.
