Every Sigma season plan comes in three programs. Pick the one that matches how you farm today.
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.
Sigma Bio granulars, Sigma liquids, Humate, Sunflower Hull Ash and Biochar, stage by stage.
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.
Sigma 2-4-2 Bio 2X blended into your fertilizer, with Sigma Bio, Seaweed, Microalgae and K-Ferm in the furrow, drip or tank.
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.
Standard synthetic rates by crop group from university extension ranges, for comparison.
