Soil and Land Management

We work to improve best management practices related to irrigation, salinity, nutrient management and toxic metals across a range of arid and semi-arid systems.

Best management practices are sets of methodologies designed to maximize production efficiency while minimizing environmental impact from crop production. They may include methods of minimizing dust production and use of non-conventional practices such as application of biochar to farmland.

Irrigation management programs focus on quantifying crop water needs and developing efficient water delivery systems, which is used for both water supply to growing plants and to manage the buildup of soil salts. Crop production programs establish nutrient requirements and evaluate nutrient sources and management systems that are applied to development of agricultural best management practices. Restoration of mined lands and other disturbed areas requires special attention to attenuation of contaminants such as heavy metals.
