IMPRINTING : Does It Work?
The research of the Imprinting Foundation is based upon Whitman's words. Facts are provided to validate rainwater infiltration theory, and the theory unifies many assorted infiltration facts. Imprinting is based upon this infiltration theory that is well supported by infiltration data collected in four states: Wisconsin, Montana, Nevada & Arizona, during the period 1960 to 1975, primarily by Dr. Robert Dixon, shown right (we know, the resemblance to Sam Elliot is uncanny!)
The Dixon Land Imprinter (one shown at right) is a very simple machine consisting of only two moving parts--the imprinting roller and the seedbox agitator. Imprinters have been designed for ecological restoration and the establishment of cover crops. They have smaller diameter rollers and are easier to transport. Some can work on 2:1 slopes and even steeper. Click on left menu or on picture for imprinter specifications.
Simple seeders, are directly driven from the imprinting roller, such as the roller shown on the right, and can deliver complex mixes of native seeds to the roller top where they are carried forward, dropped on the soil surface and then imbedded in the imprint surfaces.Click on left menu or on picture for roller specifications.
V-shaped imprints funnel resources downward where they can work in concert to germinate seeds and establish seedlings. See the photograph on the right (now that is a framable work of art!) The vegetative response to imprinting is rapid because the v-shaped imprints or indentations hold rainwater in place and captures seed, water and windblown plant litter. So it is a unique combination of factors that make this V-shaped imprint very successful: It concentrates water and seed, funneling it to the bottom of the imprint; captures and concentrates windblown litter, that works as mulch to suppress evaporation; and gathers other windblown seeds for a cover crop and biodiversity. Advantages of imprinting over other methods include better soil and water conservation, better stands of vegetation, faster growing seedlings, and greater production of forage/plant material.
