Relationships between species diversity, productivity, temporal stability of productivity, and plant invasion have been well documented in grasslands, and these relationships could translate to improved agricultural sustainability. However, few studies have explored these relationships in agricultural contexts where fertility and weeds are managed. Using 7 years of biomass yield and species composition data from 12 species mixture treatments varying in native species diversity, we found that species richness increased yield and interannual yield stability by reducing weed abundance.

Morphological identification of A. palmeri from other Amaranthus species is extremely difficult in seeds, which has led to genetic testing for seed identification in commercial seed lots.

- Winter cover crops like winter camelina and pennycress may help reduce nutrient leaching in the Upper Midwest by improving soil health and nutrient retention.
- Research measured nitrogen in plant biomass and soil, showing that winter rye and forage radish sequestered significant nitrogen in the fall, while oilseed cover crops outperformed in spring nitrogen uptake before soybean planting.
- Overall, these cash cover crops not only provide economic benefits for farmers but also contribute to environmental sustainability by reducing nutrient loss from the soil.
