It&rsquo;s all about fewer passes and efficiency.&rdquo; The west-central Minnesota farmer transitioned from ridge-till and rotated corn/soybeans to strip-tilling continuous corn with variable-rate P and K banding. The system gives him the best possible seedbeds, he says. &ldquo;Now, because it&rsquo;s working and I&rsquo;ve reduced my inputs, I feel positioned for lower corn prices.&rdquo;
