A novel form of hydroponic culture was employed to explore the physiological function of roots of a tea plant (Camellia sinensis). The pH of the nutrient solution with an actively growing tea plant decreased during cultivation. Furthermore, no oxalic acid, tartaric acid, malic acid or citric acid, all possible factors in acidification, was detected in the nutrient solution of a growing plant. A...

The hydroponic method is a of planting using media other than natural soil, including water. Hydroponic plant cultivation exists in nutrient solution but not from the soil. advantage that only uses narrow land as medium. By utilizing used glass can also be to make cultivation. In this community service activity, training and socialization on were carried out optimize Pacul Village, Bojonegoro s...

Hydroponic systems are an attractive form of urban agriculture due to their low weight load, inert substrate conditions, and overall better control plant nutrition growth. However, gaining food sovereignty cannot be at the cost increasing environmental impacts, such as eutrophication nonrenewable resource depletion, associated with phosphorus fertilizer use. Struvite, a wastewater byproduct, is...

Abstract The uptake of plant nutrients causes nutritional imbalances in hydroponic recirculating systems. Generally, the biological parameters nutrition solution systems are regulated by pH and that affect health; thus, they must be monitored managed. In order to solve this issue, a fuzzy logic-based automated control system for intelligent hydroponics was developed. This paper describes implem...
