Kernza Wheatgrass: Drought-Proofing CA Farms
TL;DR: Perennial grain crops like Kernza offer a sustainable alternative to annuals, boosting drought resilience, soil health, and farmer prosperity.
- Kernza reduces erosion and nitrate leaching.
- Deep roots enhance carbon sequestration.
- Lower inputs improve farm profitability.
- Dual-use for grain and forage.
- Field-tested data supports adoption.
Why it matters: Perennial grains can revolutionize agriculture by providing continuous ground cover, reducing environmental impact, and offering new economic opportunities for farmers facing climate challenges.
Do this next: Research local availability and trials of Kernza or other perennial grain crops in your region.
Recommended for: Farmers, agronomists, and land managers seeking resilient and profitable cropping systems that address climate change and enhance ecological outcomes.
This SARE-funded project tests Kernza, a grain-type intermediate wheatgrass genetically related to common wheat, as a sustainable perennial cropping system in California farmlands affected by drought and climate change. Objectives include establishing best practices for replacing winter oats with Kernza, measuring grain and biomass production over two years, assessing marketability, and quantifying environmental benefits like reduced soil erosion, nitrate leaching, and increased carbon sequestration. Practical protocols involve developing seeding, tillage reduction, and management techniques tailored to local climates, with reduced inputs in seeds, energy, labor, fertilizers, and pesticides translating to economic gains for farmers. The project outlines specific steps: testing establishment protocols, monitoring year-1 and year-2 yields for grain (human-edible) and biomass (forage/feed), evaluating market potential for products, and conducting outreach to farmers and students via demonstrations. Environmental advantages stem from Kernza's deep roots anchoring soil year-round, minimizing disturbance compared to annuals. Implementation details emphasize low-tillage planting, optimized irrigation for drought-prone areas, and integration into existing rotations. Success metrics include quantifiable reductions in erosion and inputs, alongside profitability assessments. Outreach components educate on dual-use systems (grain + forage), fostering adoption among next-generation farmers. This hands-on project provides field-tested data and protocols for practitioners seeking resilient, low-maintenance crops that combat climate impacts while boosting rural economies through marketable perennial products.
