| Plants take up nitrogen principally in the form of nitrate and ammonium; however, evidence is growing that they can also utilize organic nitrogen in the form of amino acids and soluble proteins. We are conducting research to determine whether wheat grown in soil fertilized with organic N utilizes more organic N directly than wheat grown with inorganic N. We are also testing for differences in uptake of amino acids between pre 1930s varieties and modern varieties of wheat to determine whether this trait has been selected for or against by breeding under high inorganic N input. Preliminary results show both wheat varieties Arco and Madsen take up 14C labeled glycine under sterile conditions. Further experiments to determine the role of microbial... |

Here we propose a policy framework that triggers the required transition. Organic agriculture, although not a silver bullet, is a useful component in such strategy. |
