What is GPS Biochar
Green Prarie Seed’s Biochar is produced primarily from poultry manure that’s heated in a low-oxygen reactor (pyrolysis). The process locks carbon, concentrates nutrients, and leaves you with a lightweight, highly porous, nutrient dense amendment that keeps working for years.

WHY CHOOSE GPS BIOCHAR?
- Most wood-char is just carbon, great for structure but light on plant nutrition. GPS starts with virtually pure poultry manure, not diluted with sawdust or wood chips. The result: the same porous “carbon sponge” wood-char provides plus a natural boost of N-P-K and trace minerals. That nutrient punch is what elevates our to a premium grade of biochar.
- Gasified for purity, zero pathogens, zero weed seeds.
- Field-proven ROI: higher yields, lower input costs.
- Shipped bulk, or small bags, ready for spreaders, or broadcast rigs.
APPLICATION RATE
- One time field application of 1,000lbs to 1,500lbs per acre.
- 2-3 pounds per tree planting or dressing existing trees.
- For gardens spread up to 1 inch on top and till 3 to 8 inches deep.
