Organic fertilizer regimens consisting of combinations of composts (yard waste, swine manure, or spent mushroom substrate) and liquid fertilizers (fishor plant-based) were evaluated against conventional hydroponic fertilizers in two experiments with greenhouse tomatoes grown in peat-based substrate. Crop yield and fruit quality were evaluated and several assays of substrate microbial activity a...

Vectobac G (Bacillus thuringiensis israelensis) application at 1.08 and 0.54g/ m to subirrigated pot and suspended forestry tube methods of non-circulating hydroponics in an unreplicated experiment greatly reduced numbers of Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), larvae and pupae compared to non-treated controls. Both Vectobac G rates, however, reduced lettuce head...

The use of hydroponic systems for growing crops is becoming increasingly popular due to its efficiency and sustainability. However, monitoring controlling these can be challenging time-consuming. This where the Internet Things (IoT) comes into play, as it allows real-time control from anywhere at any time. In this paper, we explore IoT units, including sensors measuring various parameters such ...

The optimal operation of commercial hydroponic systems depends mainly on the appropriate timely management of the available water sources, especially under saline conditions, as well as on the optimal management of fertilizer injection. In this paper, a decision support system (DSS) for the optimal, on-line, water and fertilizer management of hydroponics is presented. An on-line system, which o...
