No-till & conservation tillage agriculture is GROWING & has many BENEFITS over conventional till BUT also has challenges. Eric discusses this COMPLEXITY with COLORFUL examples & images, cutting-edge SCIENCE, and RESEARCH efforts to develop cover crop-based reduced-tillage methods for VEGETABLE production in California's tillage-intensive Salinas Valley, (America's Salad Bowl). Can these CARBON-FRIENDLY practices help sequester soil carbon and reduce CLIMATE CHANGE? Do no-till systems yield more? Should high-value organic & conventional vegetable farms eliminate or reduce tillage or should other LOWER HANGING fruit to increase agricultural sustainability be addressed first (i.e., cover cropping in conventional tilled systems)?
