Phosphorus dynamics elucidated in runoff study

Long-term field study aims to better understand impact of cover crops on nutrient loss with surface runoff.

A multidisciplinary team of scientists led by Antonio Mallarino, professor of agronomy at Iowa State University, has completed two years of a long-term field study to better understand the impact of cover crops on nutrient loss with surface runoff.

Cover crops are a recognized nutrient management practice outlined in the Iowa Nutrient Reduction Strategy. While their effectiveness in reducing the amount of nitrogen lost to subsurface drainage and soil loss from erosion has been proved,
