Comparison of Land, Water, and Energy Requirements of Lettuce Grown Using Hydroponic vs. Conventional Agricultural Methods
The land, water, and energy requirements of hydroponics were compared to those of conventional agriculture by example of lettuce production in Yuma, Arizona, USA. Data were obtained from crop budgets and governmental agricultural statistics, and contrasted with theoretical data for hydroponic lettuce production derived by using engineering equations populated with literature values. Yields of l...
متن کاملPretreatment of Brackish Water Using DC-Electrocoagulation- Method and Optimization
Electrochemically generated iron can remove most contaminants present in water and wast water, by precipitation, adsorption, electrostatic interaction, and complex formation (generally called electrocoagulation-EC). In the present paper, pretreatment of brackish water having high total hardness (TH), alkalinity (A), and Cl¯ ions, is studied by application of a DC-electrical current ot the ...
متن کاملeffect of humic acid growth and nutrient uptake of lettuce using nft system
abstract beneficial effects of humic substances on plant growth have been recognized by many researchers. a greenhouse experiment was conducted with humic acid (0, 20 and 50 mg/l) on lettuce cultivars ‘lollorossa’ and ‘javelina’ using completely randomized design at university of guilan. results showed that humic acid affected (p<5%) leaf number, height and nutrient uptake as well as ca, p and ...
متن کاملPEG imposed water deficit and physiological alterations in hydroponic cabbage .
Drought is one of the major environmental problems in agricultural field worldwide. The present study investigated the effects of water deficit caused by exogenous application of polyethylene glycol (PEG) on cabbage (Brassica oleracea var. capitata) grown in hydroponic culture. Root length, shoot length, dry weight, and relative water content of the seedlings significantly decreased in dose dep...
متن کاملAn integrated fish-plankton aquaculture system in brackish water.
Integrated Multi-Trophic Aquaculture takes advantage of the mutualism between some detritivorous fish and phytoplankton. The fish recycle nutrients by consuming live (and dead) algae and provide the inorganic carbon to fuel the growth of live algae. In the meanwhile, algae purify the water and generate the oxygen required by fishes. Such mechanism stabilizes the functioning of an artificially r...
