Injectable Liquid Fertilizer

Vigor and color without excess growth.


N-Control is a patented liquid urea sulfate (DCDS) that reduces or completely eliminates volatilization loss normally associated with nitrogen fertilization, particularly in alkaline situations.

N-Control aids in plant assimilation of phosphorus and micronutrients.

N-Control is designed specifically for fertigation in alkaline water. N-Control adds energy to the irrigation water, increasing infiltration and aeration of media and soils.

N-Control is immediately available to the plant and protected from environmental volatilization, which allows the micro feeding of nitrogen to exactly control plant utilization.

N-Control is a fertigation product and should not be used as a spray.

Store N-Control in poly, stainless steel or fiberglass tanks. Do not use mild steel or aluminum.

Do not mix N-Control with alkaline products.

N-Control contains 3.4 #’s nitrogen and 1.06 #’s sulfur per gallon. N-Control weighs 11.8 #‘s per gallon and in university test performed equal to slow-release nitrogen's on golf course greens.

Sprinkler Irrigation (Golf Courses):

For maximum visual response on fairways, greens and tees, use a total of 10 to 14 gallons of N-Control per acre over two irrigation cycles to insure good coverage. For best results use N-Control at 1-2 gallons per acre inch of water applied per month. Rates can be reduced to achieve desired growth.

Nurseries and Greenhouses:

N-Control should be used at 25% of the usual rate i.e. If 100 to 200 parts per million was normally applied, use 25 to 50 ppm of N-Control. N-control is safe for seedlings and propagation houses, when used as directed.

Trees and Shrubs:

Apply 3 to 5 gallons of N-Control per acre with the irrigation water every 7 to 10 days beginning at full leaf stages.

Drip Irrigation:

Apply 2 to 5 gallons of N-Control per acre with irrigation. Repeat every 7 to 10 days as necessary.


Consult Distributor or Manufacturer for use rates on low pH water (below pH 6). If used in aluminum irrigation lines flush lines after use.

Keep out of reach of children. Avoid contact with eyes. Flush eyes immediately and contact a physician in case of eye contact. Do NOT take internally. Keep cap tightly closed in storage.
