To counter the vast input data requirements that are typical of these models, the crop water productivity model AquaCrop adopts a semi-quantitative approach. Instead of providing nutrient levels, users of the model provide the soil fertility level as a model input. This level is expressed in terms of the expected impact on crop biomass production, which can be observed in the field or obtained from statistics of agricultural production. The present study is the first to describe extensively, and to calibrate and evaluate, the semi-quantitative approach of the AquaCrop model, which simulates the effect of soil fertility stress on crop production as a combination of slower canopy expansion, reduced maximum canopy cover, early decline in canopy cover and lower biomass water productivity. AquaCrop's fertility response algorithms are evaluated here against field experiments with tef ( Eragrostis tef (Zucc.) Trotter) in Ethiopia, with maize ( Zea mays L.) and wheat ( Triticum aestivum L.) in Nepal, and with quinoa ( Chenopodium quinoa Willd.) in Bolivia. It is demonstrated that AquaCrop is able to simulate the soil water content in the root zone, and the crop's canopy development, dry above-ground biomass development, final biomass and grain yield, under different soil fertility levels, for all four crops. Under combined soil water stress and soil fertility stress, the model predicts final grain yield with a relative root-mean-square error of only 11–13% for maize, wheat and quinoa, and 34% for tef. The present study shows that the semi-quantitative soil fertility approach of the AquaCrop model performs well and that the model can be applied, after case-specific calibration, to the simulation of crop production under different levels of soil fertility stress for various environmental conditions, without requiring detailed field observations on soil nutrient content.}, number={7}, journal={The Journal of Agricultural Science}, publisher={Cambridge University Press (CUP)}, author={Van Gaelen, H. and Tsegay, A. and Delbecque, N. and Shrestha, N. and Garcia, M. and Fajardo, H. and Miranda, R. and Vanuytrecht, E. and Abrha, B. and Diels, J. and et al.}, year={2015}, pages={1218–1233} }
