Since 2002, the Sustainable Nitrogen Management Program (PGDA), which is the transposition of the Nitrate Directive 91/676/EEC in Wallonia (Be), has defined "good agricultural practices" to reduce detrimental environmental impacts while maintaining farmers and crop productivity. However, optimizing fertilization management remains complex, since the effects of application are temporally separated from the moment of their application. This research aims to develop a decision support tool (DSS) to optimize N fertilization of winter wheat (Triticum aestivum L.), meeting both productivity criteria and PGDA requirements. The STICS soil-crop model (INRA, France) has been used to study the effects N management, soil and climate conditions on wheat growth. The tool developed for the management and optimization of N consists of a stochastic study where agronomic (yields) and environmental outputs (soil N content) are simulated under a wide range of fertilization levels and climatic conditions (derived here from LARS-WG - Rothamsted, UK). Finally, decision rules, integrating agronomic, economic and environmental criteria have been defined, to objectify the optimization of N. On this basis, a DSS has been developed allowing strategic or tactical management of fertilization. The results obtained suggest that, 75% of the time, 15 to 35 kgN. ha-1, could be saved on the fraction of N usually brought to the Zadok 39 stage, respectively based on economic or environmental considerations.

To date, research on preharvest sprouted (PHS) wheat has mostly been conducted on kernels germinated under laboratory conditions, which differ widely from conditions in the field. To obtain detailed knowledge of the evolution of hydrolytic enzyme activities in PHS wheat Triticum aestivum), a broad collection of samples from three varieties was obtained by harvesting before, at, and after maturity. Delaying harvest time coupled with periods of heavy rainfall caused sprouting in the kernels, observed as a drop in Falling Number and an increase in α-amylase activity. The appearance of α- and β-amylase, peptidase, and endoxylanase activity during field sprouting was independent from each other. Consequently, Falling Number could not be used to predict activity of other hydrolytic enzymes. When differentiating endogenous from kernel-associated microbial enzymes, results showed that α- and β-amylase and peptidase activity of PHS kernels were predominantly of endogenous origin, whereas endoxylanase activity was largely from microbial origin.

The objective of this study is to characterize the impact of tillage management and nitrogen fertilization on the root system development of a winter wheat crop. To reach this objective, an innovative root quantification method that combines NIR hyperspectral imaging (NIR-HSI) and chemometric tools will be applied. [less ▲]
