EU-Rotate_N – a Decision Support System – to Predict Environmental and Economic Consequences of the Management of Nitrogen Fertiliser in Crop Rotations
A model has been developed which assesses the economic and environmental performance of crop rotations, in both conventional and organic cropping, for over 70 arable and horticultural crops, and a wide range of growing conditions in Europe. The model, though originally based on the N_ABLE model...

| Sumario: | A model has been developed which assesses the
economic and environmental performance of crop
rotations, in both conventional and organic cropping,
for over 70 arable and horticultural crops, and a wide
range of growing conditions in Europe. The model,
though originally based on the N_ABLE model, has
been completely rewritten and contains new routines
to simulate root development, the mineralisation and
release of nitrogen (N) from soil organic matter and
crop residues, and water dynamics in soil. New
routines have been added to estimate the effects of
sub-optimal rates of N and spacing on the marketable
outputs and gross margins. The model provides a
mechanism for generating scenarios to represent a
range of differing crop and fertiliser management
strategies which can be used to evaluate their effects
on yield, gross margin and losses of nitrogen through
leaching. Such testing has revealed that nitrogen management
can be improved and that there is potential to
increase gross margins whilst reducing nitrogen losses. |
