Hydroponics

Definition Hydroponics is a subset of hydro finish and is a mode of growing workss using mineral nutritive radicals, in water, without reproach. mundane plants may be grown with their roots in the mineral nutrient stem only or in an apathetic middling, such as perlite, bugger off, mineral wool, expanded clay or coconut husk. verbal description of Methods The two chief(prenominal) types of aquiculture ar solution close and medium culture. Solution culture does not use a solid medium for the roots, just the nutrient solution. The three main types of solution cultures are static solution culture, continuous-flow solution culture and aeroponics. The medium culture method has a solid medium for the roots and is named for the type of medium, e.g., sand culture, gravel culture, or rockwool culture. thither are two main variations for distributively medium, sub-irrigation and top irrigation For any techniques, most hydroponic reservoirs are flat built of plastic, barely other materials have been used including concrete, glass, metal, veg solids, and wood. The containers should exclude sparkle to prevent algae growth in the nutrient solution.

Advantages: some(prenominal) of the reasons why hydroponics is being adapted most the man for food production are the following: No soil is needed The water stays in the transcription and can be reused - thus, lower water costs It is feasible to control the support levels in their entirety - thus, lower nutrition costs No nutrition contamination is released into the environment because of the controlled dodging Stable and high yields Pests and diseases are easier to ge! t give up of than in soil because of the containers mobility It is easier to harvest No pesticide damage Disadvantages: Without soil as a buffer, any failure to the hydroponic system leads to rapid plant death. Other disadvantages include pathogen attacks such as damp-off due to Verticillium sag caused by the high moisture levels associated with hydroponics and over watering of...If you want to get a extensive essay, order it on our website: OrderCustomPaper.com
