Soil Regeneration Kit – Biochar + Mycorrhizae + Cover Crop Seeds

Tired of low yields and dead soil? This 3-part soil kit restores microbial life in 90 days. Includes 40 lbs of activated biochar (holds 5x its weight in water and nutrients), 2 lbs of endo-mycorrhizae powder (colonizes roots), and 5 lbs of mixed cover crop seeds (crimson clover, daikon radish, buckwheat). Covers up to 2,500 sq ft. Unlike synthetic fertilizers that give a 2-week boost, this kit builds permanent soil structure. Developed with UC Davis agronomists. Comes with a soil testing strip kit and a 30-page regeneration guide. Perfect for serious home gardeners or small farms.
