Sigma formulas come in three lines. Build your brand on one, or carry all three.
Organic inputs, start to finish
Sigma Bio granulars, liquids and soil carbon only. Organic nitrogen, humate and beneficial microbes go out with every application.
Best for: Certified organic growers, organic-preferred sites and anyone building soil first.
The Sigma Bio line under your brand: organic granulars and liquids manufactured and packaged in the USA under one Sigma standard.
The bridge from conventional to organic: the best of both worlds
Conventional nutrition with Sigma biology and carbon built in: either a Sigma Bio Bridge grade (conventional nitrogen on an organic, biological base) or Sigma Bio products blended or tank-mixed into the program you run now.
Best for: Conventional growers and turf managers who want healthier soil without giving up the analysis, results or price point they count on.
The Sigma Bridge line under your brand: higher analysis and a sharper price point on an organic, biological base.
The standard synthetic program
Straight synthetic fertilizer at typical rates. We show it as the reference point, so every Organic and Bridge program can be compared against it.
Best for: The baseline. Add Sigma biology to it and it becomes a Bridge program.
Need straight conventional products to round out your line? We source them for you.
