Development of a Closed,Cost-and Energy-Saving Hydroponic System for Hillside Tomato Production
Hydroponic System Hillside Tomato Production reservoir tank
2009/7/10
To avoid problems, such as lifting soil and soil borne diseases, when growing tomatoes on hillside fields, we developed a hydroponic system for sloped land. First, we investigated an irrigation system...
A Dynamic Control of Concentration of Nutrient Solution for a Long-Term Forcing Culture of Tomatoes in a Closed Hydroponic System
culture type nitrogen nutrient solution
2009/7/8
Control of the concentration of nutrient solution for a long-term forcing culture (LTFC) of tomatoes was studied in a non-circulating closed hydroponic system that was developed in order to decrease t...
Effect of Composition of an Improved Nutrient Solution for a Closed Hydroponic System on Nutrient Absorption by Tomatoes
nutrient concentration rate of nutrient uptake ratio of nutrient absorption per water consumption (n/w) to nutrient concentration
2009/7/8
Tomatoes were grown in a greenhouse using a hydroponic system with an improved nutrient solution (NO3−N : NH4−N : P : K : Ca : Mg : SO4 = 7.0 : 0.2 : 2.1 : 5.6 : 2.9 : 1.0 : 1.1 me · LW...
