Real-time monitoring of vegetative parameters for plant-growing systems enables process optimization in agriculture. The data gathering including temperature, moisture, pH, nutrient content, optical parameters, and NDVI describes the actual requirements for a plant growing. Keeping the parameters within the limits for a specific species is necessary for an optimal growth and maximized harvest. The precise monitoring based on artificial intelligence and neural networks significantly improves water, fertilizer, and nutrient management. Using our Smart plant-monitoring system the farmers can achieve cultivation costs reduction up to 40%.
