Producers often use a selected tillage system based on tradition and their familiarity with it. They need to "push the pencil" some when considering changes in their tillage operations to compare options and alternatives. Gleaning from others' experiences before choosing a tillage system or investing in new or different equipment can be cost-effective as well. To minimize equipment needs, the selection of a tillage system should consider all crops in the crop rotation across all the soils of the farm. However, there may be some soils or some crops which may perform better with a different tillage system than the system selected for the rest of the farm. In these situations, a careful machinery analysis needs to be performed to see if the yield benefits would cover the additional fixed and variable costs of two or more tillage and planting systems.

Under strip-till, farmers till narrow 6- to inch-wide strips between rows. Fertilizer is often injected into the strip during strip-tilling. Tilled strips correspond to planter row widths of the next crop. Next spring, seed is planted into the tilled strips.
Strip-till is a conservation system that uses a minimum tillage. It combines the soil drying and warming benefits of conventional tillage with the soil-protecting advantages of no-till by disturbing only the portion of the soil that is to contain the seed row. Each row that has been strip-tilled is usually about eight to ten inches wide. In reduced tillage strategies, weed suppression can be difficult.

The monocultures he has researched include Austrian winter field pea, hairy vetch, crimson clover and wheat, and the mixed species included rye, wheat, hairy vetch, turnips and radishes. Cover crops are planted at lower than full seeding rates, which may differ from information seen in other parts of the country, he says. We have seen an increase in our soil nitrogen in the upper 6 inches, particularly following legume monospecies. We have seen a visible response to cotton behind those cover crops.
