“…Equations and are used in the crop model to define the RUE response to temperature (Villalobos et al ). For nitrogen deficit, NAB is the amount of absorbed nitrogen in the considered cropping period and NNI is the sum of 1 minus nitrogen nutrition index, which indicates crop nitrogen deficit (Lemaire and Meynard ; Debaeke et al ).

“…nitrogen availability at the root surface), assimilation and partitioning of nitrogen. Gonzalez-Dugo and colleagues have investigated the influence of water on nitrogen-related processes in forages, and they advanced a conceptual framework for the interpretation of experiments (Gonzalez-Dugo et al , 2010Durand et al 2010;Debaeke et al 2012). In drying soil, three processes-mineralisation, mass flow and diffusion of nitrogen-are impaired and collectively this can reduce the availability of nitrogen at the root surface; a high root : shoot ratio may partially compensate these effects.…”
