    • Assessing nutrient availability variations in landscapes 

      Qian, P.; Schoenau, J.J.; Cowell, L.E.; Dennis, L. (1994-02-24)
      A simple method was developed to assess the variability in nutrient availability in undulating landscapes using anion-exchange resin strip burial. Resin strips were buried in ten farm fields along transects at points in ...
    • Assessing soil N availability indices - is inorganic N enough? 

      Walley, F.; Yates, T.; Jokic, A.; Masutti, M. (2003-02-18)
      Assessing soil N availability is complicated enormously by the complexity of the N-cycle. Over the years, several methods of estimating potentially available N have been suggested. In an ongoing study, we have been ...
