A Coupled AquaCrop–Richards Model for Improved Crop Yield Prediction Through Physically Based Soil Water Dynamics

Irrigation and Drainage, EarlyView.
ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Maize Yield, Water Productivity and Economic Analysis Under Different Irrigation and Nitrogen Management Strategies Using Field Data and CERES‐Maize Model

Irrigation and Drainage, EarlyView.
ABSTRACT There is limited integrated evaluation of nitrogen (N) and irrigation management strategies for improving maize yield and productivity using crop models. The effects of N and irrigation on maize yield and productivity under centre pivot (CPI) and subsurface drip irrigation (SDI) using the CERES‐Maize model were investigated. N treatments were (

Evaluating Reference Evapotranspiration (ETo) Calculation Methods and Quantifying Climate‐Driven Change in Irrigation Demand Across Nepal's Terai

International Journal of Climatology, EarlyView.
Framework illustrating the comparison of different reference evapotranspiration (ETo) estimation methods and the integration of baseline ETo, crop water requirement (CWR), and irrigation water requirement (IWR) calculations with downscaled CMIP6 climate projections under SSP245 and SSP585 scenarios for the mid‐century and late‐century periods across ...

Calibration and testing of AquaCrop for selected sorghum genotypes

Water SA, 2017
Predicting yield response to water is important in rainfed agriculture. The objective of this study was to calibrate and test AquaCrop for simulating yield of 3 sorghum genotypes (PAN8816, a hybrid; Macia, an open-pollinated variety; and Ujiba, a landrace) grown during the 2013/14 and 2014/15 planting seasons (early, optimal and late planting dates ...

Intra‐Seasonal Crop Management and the Potential Benefit of Seasonal Precipitation Forecasts: Farm‐Level Embedded Risk Analysis in Ethiopia

Journal of Agricultural Economics, EarlyView.
ABSTRACT How large is the potential benefit for farmers from obtaining forecasts of total rainfall in the upcoming season? This critically depends on the local farm system and the crop management actions available to farmers to respond to the forecasts issued. Studies assessing the financial value of seasonal precipitation forecasts have so far focused

A Regional Version of the Aquacrop Model Evaluated with Satellite Retrievals and Backscatter Data

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The current intensive use of agricultural land forces a shift to more sustainable methods of crop production. Future crop demands are expected to rise due to a strong increase in population and prosperity, and the uncertainty in crop yields is expected to increase because of changing climatic conditions.

Do data from the RISMA soil monitoring network support agricultural modeling requirements?

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract The Real‐Time In‐Situ Soil Monitoring for Agriculture (RISMA) network provides soil water and agri‐environmental data for conceptualization, calibration, and validation of remote sensing and modeling products for Canadian agriculture at 32 stations in seven watersheds in Saskatchewan, Manitoba, and Ontario.

Modeling Irrigation Efficiency Paradox From Farmers' Behaviors

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Agricultural irrigation accounts for 70% of global freshwater withdrawals, highlighting its critical role in water conservation. However, numerous studies have presented the irrigation efficiency paradox, whereby increased efficiency rarely reduces water consumption.

Assessment of the AquaCrop model to simulate the impact of soil fertility management on evapotranspiration, yield, and water productivity of maize (Zea May L.) in the sub-humid agro-ecology of Nigeria

Discover Agriculture
Field experiments were conducted for two seasons in Ile-Ife, Nigeria to evaluate the performance of the AquaCrop model in simulating the effects of soil fertility management on the canopy cover (CC), soil water storages (SWS), cumulative aboveground ...

Fielding Floods for Flourishing Farms: A Framework for Assessing the Reuse of Small Flood Reservoirs as Irrigation Reservoirs

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Due to the increased intensity and frequency of droughts under a warming world, agricultural irrigation demand (AID) is likely to increase in many regions of the world—not just in semi‐arid and arid regions, but also in temperate regions. Small reservoirs have often been touted as a decentralized solution to increase water supply resilience ...
