Edge-of-field nitrate reduction practices such as bioreactors, saturated buffers and wetlands are gaining in popularity. Questions linger about how these practices work and the scale of implementation required to make progress towards Iowa's nutrient reduction strategy goals. Matt Helmers will discuss how to answer the questions.
A multidisciplinary team of scientists at Iowa State University has completed two years of a long-term field study to better understand the impacts of cover crops on nutrient loss with surface runoff.
Many crop producers are using best management practices to reduce and control nutrient loss and soil erosion from crop land. These same conservation methods can be applied to large-scale gardens and commercial vegetable production. Iowa State University Extension and Outreach is releasing two new publications about combining cover crops and strip-tillage systems and their use in vegetable production.
