Our Cool Season Soil Builder Mix includes 11 different species designed for improving soil organic matter and controlling weeds, it can also double as a Cool Season Grazing Mix for livestock. This diverse blend of legumes, grasses, brassicas, and broadleaves all work in synergy to build soil. Legumes convert nitrogen in the atmosphere and make it available to other plants while prolific grassroots improve soil aggregation and water infiltration. Brassicas are excellent scavengers of nutrients unavailable to other plants. Broadleaves for their part offer a deep taproot to break up compaction and their flowers attract beneficial insects. This combination leaves no room for weeds to grow to keep your fields clear for your next crop. If you want to improve the quality of your soil, this mix is for you!
