Roadmap For Success

Whether you want to increase seed germination, enhance rooting, provide long-lasting green color, improve plant vigor or maximize crop yield, Growth Products can point you in the right direction. Our company's focus on research & development has led to the creation of one successful product after another, each of which is cost-effective and environmentally sustainable:

  • Smart Nitrogen Nitro-30® SRN 30-0-0- a revolutionary slow-release nitrogen polymer.
  • A complete line of superior chelated liquid micronutrients.
  • Essential® Plus - a pioneering liquid organic.

Our exceptional customer service technicians can work with you personally to plan a fertilizer program or solve a plant nutrition problem.

The Nutritional Fertilizer Puzzle

Growth Products uses only the highest quality N - P - K raw materials. As a result, our finished fertilizers offer superior quality and consistent results.

  • N (Nitrogen) - Growth Products gained fame with its revolutionary Smart Nitrogen™, developed in 1984. To this day, this environmentally sound slow-release nitrogen source far surpasses any competitive products.
  • P (Phosphite) - "TKO" Phosphite, Growth Products' signature phosphorus product, is a clear liquid that is rapidly absorbed through plant leaves and roots, correcting deficiencies and enhancing plant vigor. Unlike traditional granular phosphates that often bind up in soils, "TKO" is always fully available to plants.
  • K (Potassium) - Growth Products' chloride-free potassium carbonate is cleaner, safer and more pure than other K sources such as Muriate of Potash. Plus, potassium carbonate has a low-salt index and instantly available.
  • Essential® Plus
  • Repair Plus
  • Control De-Thatcher
  • Hydro-Max
  • Re-Store Plus
  • Smart Nitrogen™

    Growth Products' Smart Nitrogen™ is smart for the environment, smart for the budget, and smart for you. And it is the key ingredient in all of Growth Products' liquid nitrogen fertilizers, including Nitro-30 with 85% Smart Nitrogen. In fact, Growth Products gained fame as the "Liquid Solutions" company when it developed the unique slow-release nitrogen polymer that lies at the heart of Smart Nitrogen. Its advantages are many and varied: dual efficiency allows it to be absorbed by both leaves and roots; anti-leaching and anti-volatilization properties make it cost-efficient and environmentally sustainable; an exceptionally low salt index eliminates the risk of phytotoxicity and prevents salt build-up in soils; and its superior agronomic performance has been proven time and time again.

    University Research

    It's not just Growth Products saying we're good. Dozens of university studies by well known and highly respected scientists have tested our products and shown that they perform exactly the way we say they do. And pitted against the competition, our products consistently generate superior real-world results. For complete details and charts of university studies visit the research section of our web site.
