Several St. Louis National No-Tillage Conference attendees who use GPS auto-steer systems raised the question of adding more GPS wizardry directly to drills, planters and sprayers for reducing costly side draft on steep slopes.

For more accurate seeding and spraying, a few no-tillers are already starting to believe that global positioning satellite systems should be placed in the ground — where it may count the most.

California has long been one of the most productive agricultural areas of the world. Partly for that reason, growers there are often understandably reluctant to try new farming methods, especially when rising fuel and labor costs and market competition are shrinking profit margins.

When you think about being directly involved with saving a natural resource as significant as the Chesapeake Bay, it’s hard not to get excited. That noble thought might be enough reason all by itself to really hard sell continuous no-till systems, including cover crops and rotations. And when you can see clearly that no-till makes farming more profitable — in addition to the big-picture environmental equation — you can start to sense that we’re onto something, as they say, that’s really big.

The essentials of no-tilling are severely tested in an area with a short growing season, just 12 inches of rain annually and the potential for frost 365 days a year. Those are the conditions that Tim Melville faces as he no-tills 3,000 acres with his sons near Enterprise, Ore., in the shadow of the Cascade Mountains.

If you’ve already harvested 70-bushel no-till soybean yields and think you’ve hit a yield plateau, Palle Pedersen says, it’s time to rethink the situation. In fact, the soybean specialist at Iowa State University maintains 100-bushel soybean yields aren’t out of the question.
