Bayesian Calibration of AquaCrop Model

2018 37th Chinese Control Conference (CCC), 2018
The AquaCrop simulation model, modelling the dynamic change of crop growth status, is an important crop management tool for quantifying crop yield response to water. To effectively simulate the soil water balance and the crop growth process, a number of system parameters and canopy state variables are inevitably adopted.

Deficit Irrigation Optimization of Cotton with AquaCrop

Agronomy Journal, 2009
Given the current pressures to reduce irrigation water use, it is important to optimize the use of water in irrigated agriculture. This work was aimed at determining the optimum level of applied irrigation water (AIW) for cotton (Gossypium hirsutum L.) production in southern Spain under several climatic and agricultural policy scenarios.

AquaCrop: FAO's crop water productivity and yield response model

Environmental Modelling and Software, 2014
With the help of relatively few conservative crop parameters, AquaCrop simulates final crop yield in four steps that are easy to understand, which makes the modeling approach transparent. The steps consist in the simulation of development of the green crop canopy cover, crop transpiration, above-ground biomass, and final crop yield.

Calibration and Testing of the FAO AquaCrop Model for Canola

Agronomy Journal, 2011
Water being a major limiting factor in crop production, prediction of the growth and yield response of crop to water is important. Field experiments were conducted in 2009 and 2010 at Wagga Wagga (Australia) to calibrate and validate a water productivity model AquaCrop for canola (Brassica napus L.). The calibrated model was able to accurately simulate

Modified AquaCrop-OpenSource tool for data-scarce regions

2022
<p>The Food and Agriculture Organization (FAO) AquaCrop model has demonstrated its ability to accurately simulate the growth of various crops. However, the quality of simulation results depends on the calibration of the model, which in turn requires field observations of model inputs and parameters.

Using AquaCrop to derive deficit irrigation schedules

Agricultural Water Management, 2010
Straightforward guidelines for deficit irrigation (DI) can help in increasing crop water productivity in agriculture. To elaborate such guidelines, crop models assist in assessing the conjunctive effect of different environmental stresses on crop yield.

Evaluation of AquaCrop model of cucumber under greenhouse cultivation

The Journal of Agricultural Science, 2020
AbstractWater consumption in agriculture is impossible without considering relations between water, soil and plant. In this regard, there are various models and developed software in order to evaluate relation between soil, water and crop growth stages. These models can be used for irrigation planning if properly optimized and applied.

Assimilation of Sentinel-1 Change Detection in the Aquacrop Model: Case of Sugarcane

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The “Compagnie Sucriere Senegalaise” (CSS) wanted to upscale the field-level crop simulation model AquaCrop (FAO's agro-meteorological model) for the automated monitoring and management of its ±13.000 ha of irrigated sugarcane. A recently developed changepoint detector was applied to Sentinel-1 time series to identify key phenological crop stages for ...

The AquaCrop model

FAO (the Food and Agriculture Organization of the United Nations) launched in 2009 the dynamic crop growth model “AquaCrop” to predict yield response to water of herbaceous crops. After a brief description of the calculation scheme and the input requirements, the chapter discusses the parametrization of AquaCrop for crops and the simulation of the ...
