N-Ext N-Charge™ 28-0-0 Enhanced Liquid Nitrogen Fertilizer

N-Ext 28-0-0 N-Charge™ is an enhanced liquid nitrogen fertilizer formulated to provide immediately available nitrogen for fast turf response and deep green lawn color. Its 28-0-0 N-P-K analysis supplies nitrogen through both foliar absorption and root uptake, helping feed the lawn from the top down and the soil up.

N-Charge is an excellent choice for spring green-up, fall nitrogen applications, and cool-season lawn nitrogen blitz programs. Foliar absorption can occur in approximately five minutes when applied with a backpack or pump sprayer. After the five-minute absorption period, water the product into the soil according to the product label.

N-Charge can be used on labeled cool-season and warm-season grass types. It is especially useful during cooler, overcast conditions in spring and fall when turf is actively growing. Warm-season lawns may benefit from N-Charge during spring and while actively growing, but a fall nitrogen blitz is not recommended for warm-season turf.

How N-Charge Works

N-Charge feeds your lawn from the top down and the bottom up. When it’s sprayed onto the grass, the blades absorb part of the nitrogen within about 5 minutes. A short watering then moves the remaining nitrogen into the soil, where the roots take it up.

N-Charge combines three forms of nitrogen: urea, ammoniacal, and nitrate. Because this nitrogen is immediately available, results show up fast, often within hours. In cool weather, root uptake slows down, so green-up through the roots may take a little longer.

Using N-Charge for a Fall Nitrogen Blitz (Cool-Season Lawns)

N-Charge is a great fit for the fall nitrogen blitz on cool-season lawns like Kentucky bluegrass, tall fescue, and ryegrass.

• Apply 16 oz per 1,000 sq ft every two weeks during fall.
  
• Each application provides about 0.36 lb of nitrogen per 1,000 sq ft.
  
• When soil temperatures drop below 40°F, make one final application as your winterizer.
  
• Following this plan keeps your lawn a deep, dark green all fall.
  

Using N-Charge on Warm-Season Lawns

On warm-season lawns like Bermuda, St. Augustine, zoysia, centipede, and bahia, N-Charge works well in spring and through the growing season. If you’re still mowing at least once a week in fall, it can also give a quick green-up. We do not recommend a fall nitrogen blitz on warm-season turf.

Application Information

• Shake well before using.
  
• Apply 16–24 oz per 1,000 sq ft every 4–6 weeks while turf is actively growing.
  
• Backpack or pump sprayer: Mix 16 oz of N-Charge per 2 gallons of water and spray evenly across 1,000 sq ft.
  
• After application, water the lawn for 5 minutes for best results.
  
• Hose-end sprayer: Set the dial to 2 oz if you’re moving slowly through the lawn, or 4 oz if you’re moving quickly. Green-up may take about 24 hours.
  
• Do not apply to saturated soil.
  
• Rinse excess product from sidewalks, driveways, and other hard surfaces to help prevent staining.
