Control of hydroponic tomato culture by periodic nutrient corrections. Application to commercial greenhouses



Control of hydroponic tomato culture by periodic nutrient corrections. Application to commercial greenhouses



Anales de Edafologia y Agrobiologia 45(5-6): 729-738



A control system for hydroponic cultures, based on periodical plant and substrate analysis is proposed. Adjustments of nutrient concentrations in the culture solution are made as necessary to maintain optimum levels throughout the culture period. The methodology was applied to tomato culture in a greenhouse, using two varieties; the plants (sap, leaf) and nutrient solutions were analysed weekly throughout the culture period.
