Quantifying the tradeoffs between different crop residue uses

Wijk, M.T. van. 2009. Quantifying the tradeoffs between different crop residue uses. Video interview with Mark van Wijk. Nairobi: ILRI.

During the December 2009 SLP meeting in Addis Ababa, Mark van Wijk (WUR) and colleagues presented some modelling work that could help quantify the tradeoffs between uses of crop residues - either incorporated in the soil to maintain soil fertility or fed to cattle. He emphasizes that the models help to quantify the consequences - 'what if' - of different decisions or strategies.
