Overview
The stale seed bed or false seed bed method is a weed control technique used at both the farm and garden scales. In this that the young weeds can then be easily eliminated. By destroying them early, the farmer or gardener eliminates most of that season's annual weeds, which reduces their labor and improves their crop yields.
Description
The stale seed bed technique of weed control was developed before herbicide use began. It reduces the soil's seed bank or quantity by allowing the weed seeds both opportunity and time to germinate, sprout, and appear before the intended crop is planted. Once the weeds appear, they are easily eliminated by various methods that minimize further soil disturbance. This cycle can be repeated numerous times before planting the crop. Early reduction of the weed seed quantity by this method reduces the need to weed for the rest of the growing season, and in some cases performs as well as chemical weed control methods.
Method
The false or stale seed bed technique can be started immediately after harvesting a field, or at least two weeks prior to planting a new crop.
Farm-scale Approach
The farm field should be worked and smoothed into a flat fine seed bed. The initial tillage is normally done with a disc harrow or a rotary tiller, rather than with a plow. If plowing is required, secondary passes with a disc or tiller will be needed. The next step is to break up clods and flatten the surface is done with a spring-tooth or spike-tooth harrow, or with a chain drag harrow, depending on the soil type. Final preparation is done with a cultipacker or other type of roller to firm the soil, which enhances seed germination.
