Integrating Machine Learning Into Process-Based Modeling to Predict Ammonia Losses From Stored Liquid Dairy Manure
… losses is necessary to inform decision-making processes to improve manure management, and design ammonia mitigation strategies. In 2003, the National Research Council recommended using process-based models to estimate emissions of pollutants, such as ammonia, from animal feeding operations. …

Data-Driven and Process-Based Modeling Approaches for Advancing Irrigation Water and Nitrogen Management in Humid Cropping Systems
… full, and precision irrigation, an event-based hydrologic signature was used to estimate field capacity (FC) and plant extraction limit (PEL) from identifiable periods of infiltration, gravity drainage, evapotranspiration, and rewetting. Compared with two existing signature methods, the …

Balancing water quality, nitrogen management, and corn production goals in Illinois
… of those practices, and (ii) explore how process-based modeling tools could be used as an integrative approach for linking sustainability outcomes with improved agronomic efficiencies. Results from a 3-yr field experiment highlighted potential environmental tradeoffs between water and air …

Regenerative agriculture and soil carbon storage in the Upper Corn Belt
… management affects SOC storage, erosion processes, and microbial community structure. Factors such as topography, time since adoption of regenerative practices, climate, and soil texture significantly influenced SOC stocks and microbial community structure. Slope and historical erosion …

Climatic and Anthropogenic Influences on Food and Water Security
… outlined objectives, a range of statistical and process-based modeling and data analytics are utilized. The first objective is achieved by developing a copula-based drought yield loss risk index for crop-producing counties. The results indicate that, historically, the growing-season droughts have …

Remote sensing-based assessment of Gross Primary Production (GPP) in agricultural ecosystems
… with eddy covariance (EC) methodology, process-based modeling of carbon gain, and satellite remotely-sensed vegetation indices (VIs). The data is brought together synthetically for major crops found in agricultural landscapes of Gwangwon Province, South Korea, e.g., rice, soybean, maize, …
