Abstract
Vegetable production in China is associated with high inputs of nitrogen, posing a risk of losses to the
environment. Organic matter mineralisation is a considerable source of nitrogen (N) which is hard to
quantify. In a two-year greenhouse cucumber experiment with different N treatments in North China,
non-observed pathways of the N cycle were estimated using the EU-Rotate_N simulation model.
EU-Rotate_N was calibrated against crop dry matter and soil moisture data to predict crop N uptake, soil
mineral N contents, N mineralisation and N loss. Crop N uptake (Modelling Efficiencies (ME) between
0.80 and 0.92) and soil mineral N contents in different soil layers (ME between 0.24 and 0.74) were
satisfactorily simulated by the model for all N treatments except for the traditional N management. The
model predicted high N mineralisation rates and N leaching losses, suggesting that previously published
estimates of N leaching for these production systems strongly underestimated the mineralisation of N
from organic matter.
