This study develops a hybrid predictive framework that integrates machine learning with a physics-based model to estimate lettuce fresh weight, leaf area, nitrate levels, and water consumption in aeroponic systems. Validation with real-time aeroponic data shows strong performance for fresh weight and total leaf area, while nitrate and water predictions are less accurate due to limited training data and constraints of the physics component under soilless conditions. The approach supports more efficient, sustainable controlled environment agriculture.","POLITECNICO DI TORINO  \nRepository ISTITUZIONALE  \nHybrid machine learning and physics-based model for estimating lettuce (Lactuca sativa) growth and resource consumption in aeroponic systems  \nOriginal  \nHybrid machine learning and physics-based model for estimating lettuce (Lactuca sativa) growth and resource consumption in aeroponic systems / Fasciolo, Benedetta; Grasso, Nicolo'; Bruno, Giulia; Chiabert, Paolo. -In:  \nSCIENTIFIC REPORTS. -ISSN 2045-2322. -ELETTRONICO. -15:1(2025) .

Climate change and environmental degradation further complicate these challenges, impacting crop productivity and food security. Traditional farming methods struggle with efficiently managing nutrients and water while ensuring high-quality products, leading to resource wastage and food safety concerns. This study aims to develop a hybrid model combining machine learning and physics-based techniques to predict fresh weight, leaf area, nitrate levels, and water consumption in lettuce grown in aeroponic systems, thereby enhancing resource management and product quality. We integrated a physics-based model with machine learning algorithms to create a dynamic hybrid framework. The model was validated with real-time data from aeroponic systems, showing good predictive performance, particularly for fresh weight and total leaf area. In contrast, predictions of nitrate content and water consumption were less accurate, due in part to smaller training datasets and limitations of the physics-based component under soilless conditions. Despite these challenges, the hybrid model offers a promising solution for optimizing controlled environment agriculture, addressing critical challenges in modern agriculture by improving efficiency and sustainability.  \nKeywords Hybrid model, Machine learning, Physics-based model, Aeroponic, IoT, Predictive model  \nOptimizing resources and agricultural production is crucial to addressing the growing global population and urbanization challenges. The world population will grow over the next sixty years from 8.2 billion in 2024 to around 10.3 billion people in the mid-2080s1. A significant increase in agricultural production will be required in the coming decades to ensure food security. However, growing urbanization and the environmental crisis pose significant threats. Climate change strongly impacts plant abiotic stress, such as high temperatures2, salinity3, and heavy metals4, compromising agricultural productivity. Moreover, the limited availability of essential resources like macro and micronutrients5 and soil pH variations further exacerbate the situation4. On the other hand, agricultural activities like deforestation6 and intensive use of fertilizers and pesticides7,8 contribute to the environmental crisis by reducing the soil organic carbon pool and causing water and air pollution. Food waste is another critical issue with significant environmental and food security implications. Approximately 14% of all food produced is estimated to be lost between the post-harvest stage and just before the retail stage9.
