    • Gross nitrogen mineralization and immobilization in temperate maize-soybean intercrops 

      Regehr, Alison; Oelbermann, Maren; Videla, Cecilia; Echarte, Laura (Springer, 2015-06)
      Background and aims: Reliance on nitrogen (N) fertilizers to maintain crop productivity requires a thorough understanding of the transformation of this nutrient within the soil-plant system. Organic matter input from a ...

    • Influence of management practices on water-related grain yield determinants
