Technical Abstract: Discussed is the identification, diagnosis, control, and reclamation of dryland saline seep problems as found in the North American Great Plains. Saline seeps develop because of geologic stratifications within the soil profile and insufficient use of precipitation by crops used in dryland farming systems. The process of saline seep development results in salinization of productive dryland soils and shallow groundwaters in localized areas. Establishing perennial deep-rooted crops in recharge areas is effective in controlling saline seeps. Establishing intensive, flexible cropping systems to improve crop water-use efficiency in combination with soil, water, and crop management practices to reduce the need for summer fallow is also effective for saline seep control. Once the saline seep area has been hydraulically controlled, reclamation procedures can be implemented. Productivity of the former seepage area can be restored to near normal yield levels with time.
