Article Adaptation and evaluation of the integrated farm system model to simulate temperate multiple-species pastures   Corson, Michael S. ; Alan Rotz, C. ; Howard Skinner, R. ; Sanderson, M. A.
Agricultural Systems, 2007 , Volume 94 , n° 2 , 502-508 p.  
Résumé :
Whole-farm simulation provides a tool for predicting the effects of farm management strategies on farm productivity and profitability. One such model, the Integrated Farm System Model (IFSM), was modified to allow representation of up to four forage species coexisting in a pasture mixture. The...

Article Analysis of the uncertainty associated with the estimation of nitrogen losses from farming systems   Payraudeau, S. ; Van der Werf, Hayo M.G. ; Vertès, Françoise
Agricultural Systems, 2007 , Volume 94 , n° 2 , 416-430 p.  
Résumé :
This work describes the analysis of the uncertainty linked to the annual direct and indirect losses of different nitrogenous compounds at the scale of a group of farms. The nitrogen (N) forms taken into account are: ammonia (NH3), nitric oxide (NO), nitrous oxide (N2O), dinitrogen (N-2) and...

Article Evaluating warm-season grass production in temperate-region pastures: A simulation approach   Corson, Michael S. ; Rotz, C. A. ; Skinner, R. H.
Agricultural Systems, 2007 , Volume 93 , n° 1-3 , 252-268 p.  
Résumé :
The pasture submodel of the Integrated Farm System Model (IFSM) was modified to simulate the biomass production and nutritive dynamics of a warm-season (C4) grass monoculture. Predictions of yield and nutritive value were calibrated and evaluated with 5 years of field data from grazed switchgrass...

Article The environmental impacts of the production of concentrated feed : the case of pig feed in Bretagne   Van der Werf, Hayo M.G. ; Petit, Jean ; Sanders, Joost
Agricultural Systems, 2005 , Volume 83 , n° 2 , p.153-177 p.  
Résumé :
Pig production systems often depend to a large extent on concentrated feed imported from outside the farm. This study used the Life Cycle Assessment (LCA) method to assess major environmental impacts associated with the production and on-farm delivery of concentrated feed for pigs. Feed...
