Abstract
This article presents an AI architecture called DMMD RL PA to optimize nutrient delivery in controlled environment agriculture, especially in vertical farms. The system fuses real-time multimodal data from spectral imaging, environmental sensors, and plant growth models so that a reinforcement learning agent dynamically adjusts nutrient formulations. In realistic simulations, a yield increase of between 15 and 20 percent and a reduction in fertilizer consumption of between 10 and 15 percent are observed compared to conventional methods.
Introduction
Urban growth demands innovative solutions for food production. Controlled environment agriculture (CEA) and vertical farming enable intensive cultivation with precise control of environmental variables. One of the key challenges is efficient nutrient management. Traditional approaches use fixed formulations that do not respond to dynamic changes in plant status. We propose DMMD RL PA, a platform based on multimodal data fusion and reinforcement learning to offer adaptive nutrient management that maximizes yield and minimizes waste.
Related Work
Previous research in precision agriculture has used sensing, predictive monitoring, and heuristic rules for irrigation and nutrition. Machine learning techniques have been used for deficiency diagnosis and yield prediction, but they often do not effectively integrate different data sources or adapt in real time. DMMD RL PA combines multimodal fusion with a reinforcement learning agent to overcome these limitations and provide proactive decisions.
System Architecture
The platform consists of four main modules. A multimodal ingestion and normalization layer that integrates spectral cameras, environmental sensors, and a plant growth model (PGM). A semantic and structural decomposition module that extracts features from text and data using transformer-type models and graph parsing. A multilayer evaluation pipeline to analyze quality, impact, and novelty. A reinforcement learning agent that uses Deep Q-Network (DQN) with the option of Proximal Policy Optimization (PPO) to adjust concentrations of nitrogen, phosphorus, potassium, and other elements. Importance weights are optimized with a combined Shapley and AHP approach.
Methodology and Experimental Design
A simulated vertical farm environment was used that replicates the growing cycle of leafy greens based on a validated physical model. The simulation incorporates sensor noise and environmental variations to test robustness. 1000 cycles were trained and 500 were validated. The reward function combines yield and fertilizer consumption: Reward equals Yield minus a times Fertilizer Consumption, where a is an empirically adjusted weighting factor. Hyperparameters were optimized using Bayesian optimization.
Mathematical Formulation
The problem is formulated as a Markov decision process (MDP) with a state space S derived from fused data, an action space A composed of nutrient formulations, a transition function P, and a reward function R. The objective is to find the optimal policy that maximizes the discounted cumulative reward applicable to dynamic nutrient management.
Evaluation Metrics and HyperScore Integration
Yield in grams per plant, fertilizer consumption in grams per plant, and nutrient use efficiency (NUE) calculated as yield divided by fertilizer were measured. The results were additionally evaluated with HyperScore criteria to quantify deviation, impact, and novelty.
Results and Discussion
In the simulated environment, DMMD RL PA outperformed fixed formulation strategies, achieving between 15 and 20 percent yield increase and 10 to 15 percent fertilizer savings. The system showed robustness against environmental variations, and sensitivity analysis indicated that the weighting factor a controls the balance between maximizing yield and reducing inputs. Future research will include plant stress detection and adjustment of the reward function by crop variety.
Conclusions
DMMD RL PA demonstrates that multimodal data fusion and reinforcement learning enable dynamic and efficient nutrient management in vertical farms, contributing to more sustainable food production. The approach is scalable for commercial implementation and provides economic and environmental benefits.
