We quantify weed emergence, survivorship, fecundity, and propagule survivorship in the soil.

These parameters can be used to assess the weed suppressiveness of different cropping systems.

Data Collection

We use image analysis to quantify ground cover in cropping systems.

We assess growth of crops and cover crops and measure other environmental variables to understand how weed and crop management affect the larger agroecosystem.
