October 25th, 2016 – Year two soil, plant, biological, and cash crop yield/quality testing was completed mid-October for all cover crop trials in Southwestern Colorado and Southeastern Utah.
- Soil tests report results on physical, chemical, and biological factors related to soil health.
- Plant tests include canopy cover, species composition, and ground cover data.
- Earthworm surveys are conducted at trial locations, as presence/absence of earthworms at are biological indicators of soil health.
- Cash crop yield (bu/acre) and quality (test weight, protein content, oil content) are analyzed to determine if cover crops make an impact on cash crops.
