Nitrogen and Water Retainment

N-KEEPER™ is designed and formulated to penetrate the toughest of soils and drive moisture down deep into the sub-surface, allowing it to be utilized during those times when the upper layers of your soil become dry and unproductive. During this dry period, the co-polymer wetting agent allows the water to be held in suspension to be wicked up into the rooting zone along with the nutrients that have been made readily available by the N-KEEPER™ complex of specialty enzymes. Another benefit of N-KEEPER™ is the ability to retain Nitrogen in the rooting zone preventing unwanted leaching and runoff!

Typical Benefits

  1. Reduced Surface Tension
  2. Increased Moisture Duration and Capacity
  3. Increased Liquid Fertilizer Holding Capacity
  4. Increased Root Mass
  5. Reduced Plant Stress
  6. 33% Increased Nitrogen Efficiency
  7. 48% Increased Phosphate Availability
  8. 90% Increased Potassium Availability

Application Information

For general use as a soil penetrant, use 8 ounces N-KEEPER™ per acre three to five times per season as needed to allow water to penetrate deep into the soil.

For use in fertilizer retainment, apply 8 ounces N-KEEPER™ per acre with your liquid fertilizer.

If water is already sitting on top of soil, apply 8 to 16 ounces N-KEEPER™ per acre. N-KEEPER™ will open the soil to take in the water and any fertilizer applied with it.
