Abstract:
Due to unexpected circumstances and personnel problems, much of the data was lost, and the data collected was of little value. Based on ancillary observations, there appears to be differences in drought tolerance within the different cover crops evaluated. We are continuing to investigate the central hypotheses that “winter and summer cover crops enhance nutrient cycling, reduce weed pressure and improve soil quality.” Grower cooperators note fall-seeded cover crop (wheat, barley) establishment is difficult under dry conditions. Growers continue to use cover crops and are interested in cover crops to take advantage of the known benefits.
Project objectives:
div style="margin-left:1em;">- To identify and evaluate winter cover crops that can help improve early plant establishment (reducing wind erosion effects and soil crusting) while minimizing interference with plant growth and soil water storage and while contributing to better farm nutrient management and soil quality;
- To identify and evaluate summer cover crops that can help improve nutrient cycling and late season weed management while minimizing water establishment requirements;
- To conduct these studies in a variety of different climatic conditions (regional within Utah), with different vegetable crops (cucurbits, tomatoes, corn, other crops) and cropping systems (organic and non-organic);
- To disseminate this information to Utah’s farmers, service agencies and other potential user groups at farm field days, through print and electronic media and at state, regional and national meetings.
