Upper Colorado Regional .dor Bill Plumraer announced that rs have been installed by the .an of Reclamation in lands that '. a part of the Jensen Unit of the Cen-; Cen-; Utah Project near Vernal . "'i State University's Agricultural :;-nment Station, Extension Ser- and Agricultural and Irrigation queering Departments are 'Hating in this study. Officials of University point out that many hun-of hun-of acres of good farmland in j as well as thousands of acres " sjhout the world, have gone out of Action because of high water tables resulting accumulation of salts. Much of this land is being reclaimed and maintained for agricultural production pro-duction by the installation of drains. Camera towers such as the one shown in the photograph have been erected on two different farms in the Jensen Unit from which a 16-mm camera is mounted. On a weekly basis, short sequences se-quences of film are taken to document the changes that occur in crop growth - because of the drains. It is intended that the photographic record thus obtained will be used to show the benefits of drainage. It can also be used as a teaching aid in the classroom and in extension ex-tension activities by the University. The time-lapse photography was started prior to the installation of the drains, was continued through the period of construction, and is being continued con-tinued during the post construction period. |
