HydroNet: An Intelligent Hydroponics Web Service Environment
In this work an intelligent web service environment for managing hydroponics cultivation processes is proposed. The environment is called HydroNet and includes information and personalized support to hydroponics’ interested groups. The aim is to give the producer the opportunity to access for the first time hydroponics consulting services that meet his/her particular needs over the web. The env...
متن کاملHydroponics Worldwide - a Technical Overview
Growing greenhouse vegetables is one of the most exacting and intense forms of all agricultural enterprises. In combination with greenhouses, hydroponics is becoming increasingly popular, especially in the United States, Canada, western Europe, and Japan. It is high technology and capital intensive. It is highly productive, conservative of water and land and protective of the environment. For p...
متن کاملDeep Flow Hydroponics - Past, Present and Future
In 1976, a method of growing lettuce and other leafy vegetables on a floating raft of expanded plastic was developed independently by researchers at the University of Arizona and the University of Pisa in Italy. Today facilities exist in a number of countries including the United States, Japan and Canada. Termed “Deep Flow Hydroponics,” the system consists of horizontal, rectangular shaped tank...
متن کاملElectrical Conductivity in Deep–trough Hydroponics
A model is presented that predicts pH and electrical conductivity (EC) changes in the root zone of lettuce (Lactuca sativa cv. Vivaldi) grown in a deep–trough hydroponic system. A feedforward neural network is the basis of that modeling. The neural network model has nine inputs (pH, EC, nutrient solution temperature, air temperature, relative humidity, light intensity, plant age, amount of adde...
متن کاملRice–arsenate interactions in hydroponics: whole genome transcriptional analysis
Rice (Oryza sativa) varieties that are arsenate-tolerant (Bala) and -sensitive (Azucena) were used to conduct a transcriptome analysis of the response of rice seedlings to sodium arsenate (AsV) in hydroponic solution. RNA extracted from the roots of three replicate experiments of plants grown for 1 week in phosphate-free nutrient with or without 13.3 muM AsV was used to challenge the Affymetrix...
