Abstract

Context or Problems: The impact of different agronomic strategies (such as sowing, fertilization, and tillage) under different environmental conditions (soil type, and long-term weather conditions) can provide an increased knowledge on how barley grain yield, quality and environmental footprints can be optimized. Objectives: The objectives of this study are to: i) understand what are the different agronomic and environmental combinations that optimize grain quality and minimize environmental impacts; ii) which environmental-agronomic combination allow production and quality stability to be achieved over time, while providing lower environmental footprints. Methods: An existing crop simulation model was calibrated on a nitrogen response experiment and evaluated on an independent dataset of nitrogen response. Results: Overall, the interaction of sowing, soil type, fertilization and tillage impacted grain quality more than grain yield. The optimization of the environmental, economic and quality outcome is strongly soil-climate dependent to optimizing grain quality and minimizing environmental impacts. Rainfall in pre-sowing, vegetative and reproductive stages is the most important environmental parameter impacting grain yield. While grain quality needed for malting/distilling is impacted by interaction of weather and agronomic practices. Conclusions: In Mediterranean environments, optimizing for quality, yield and lower environmental impacts is challenging, and crop simulations can help to provide useful information on the dynamic interactions of those factors. Implications: The tradeoff indicator can be derived considering how agronomy-soil-weather interactions impact the relationship between net income and environmental implications (in terms of nitrogen losses). This indicator can be used for building a tool to be used with system-based models to evaluate at different spatial scales the impacts of different agronomic management (as impacted by weather variability) on economic and environmental sustainability.
