Slow-Release Nitrogen with Soil-Building Benefits

The difference is longevity. Replenish 16-0-5 delivers long-lasting nitrogen while supporting soil biology and plant health.

Replenish 16-0-5 is a 50% WIN organic-based fertilizer designed to provide sustained performance while building soil health. Combining high-quality methylene urea for long-term color, ammonium sulfate for quick response, and Replenish compost to enhance microbial activity and balance C:N ratios, this product ensures strong turf growth across fairways, roughs, sports fields, and landscapes.

Why Balanced Nitrogen & Soil Matter

Nitrogen and healthy soil biology work together to:

  • Provide steady, long-lasting color and growth
  • Stimulate microbial activity for improved nutrient cycling
  • Enhance nutrient mobility, including macro- and micronutrients
  • Support soil structure and calcium levels for stronger turf

The Soil & Plant Challenge

  • Rapid-release fertilizers can cause short-lived color and potential stress
  • Depleted soils limit microbial activity and nutrient availability
  • Imbalanced C:N ratios reduce nitrogen efficiency

The Replenish 16-0-5 Solution

  • Combines methylene urea, ammonium sulfate, and organic Replenish compost
  • Delivers long-lasting nitrogen while supporting microbial activity
  • Buffers soils with calcium to strengthen turf and mitigate sodium and bicarbonate stress
  • Promotes sustained turf color, growth, and overall soil health

The source of carbon serves as food for microbes.
