The Imprinting Foundation: New Hope for Damaged Lands
Dedicated to the development and extension of new technologies
The conservation tillage innovation called land imprinting was invented in 1976 and then patented in 1980. This science-based innovation is uniquely capable of nearly total conservation of soil and water resources to ensure successful revegetation even in arid land areas such as the Mojave Desert that receives, on an average, 76 mm (3 inches) of rainfall, annually.
The science and technology of sustainable agriculture and ecological restoration are merging into a single discipline with the passage of time. Agronomists are applying some ecology and ecologists are applying agronomy in their sustainable agriculture and ecological restoration projects. This merger of the two disciplines is being driven by a common concern over global land degradation or desertification that threatens the welfare and even survival of all species, including our own.*
While world population of humans is growing rapidly, the acreage of productive land is shrinking and we are now experiencing shortages of food and medicine worldwide. Agricultural lands are becoming degraded or desertified and are thus less able to provide sustained production of food, feed, and fiber, while becoming an increasing source of environmental pollution. Likewise natural lands are becoming degraded and are thus less able to provide the services of healthy ecosystems such as clean soil, water and air, pollination and abundant and diverse medicinal plants.**
Land degradation or desertification is caused by such human activities as livestock grazing, forest and woodland logging, land tillage, outdoor recreation, urban and industrial development, and military activities. The foregoing activities cause well vegetated land to become denuded, thereby decreasing rainwater infiltration and increasing water runoff, erosion, sedimentation and flash flooding.*** The degraded land is less able to infiltrate and hold soil moisture; consequently, plants experience a more arid environment, especially during short term droughts. A vicious cycle of land aridification and denudation forms the insidious process called desertification, wherein the land dries out and many life forms die or flee.**** The no-till method for seeding, called land imprinting, has been under development in Tucson, Arizona since 1976. Ranchers have applied imprinting to restore perennial grasses on their degraded rangeland for erosion control and forage production. The degradation has been due to a variety of reasons: overgrazing, fires, over farming, and relatively recently discovered/publicized global warming. To the right above is barren land before imprinting.
The next picture shows land "imprinted" in order to collect moisture and nutrients/resources where the climate produces very little precipitation. More and more lands are facing droughts and low moisture levels due to global warming. Click on the Barren Land picture to learn more about this very serious problem. Click on the Imprints picture for one solution re:soil. The Dixon Land Imprinter, shown at right, has been used to interseed 100,000 acres with grasses in southern Arizona since 1980. Early imprinters were massive machines with large diameter rollers that were designed to operate on rocky, brushy terrain of the southwestern deserts. The Dixon Land Imprinter is a very simple machine consisting of only two moving parts--the imprinting roller and the seedbox agitator. Click on the picture for specifications. This machine was invented by Dr. Robert Dixon, internationally known soil scientist, leading authority on sustainable agriculture, revegetation, interseeding, reclamation seeding, and erosion control (to list just a few of the topics on which he has lectured/published scientific writings).
