Hydroponics is a subset of hydro finish and is a method of growing workss using mineral nutrient radicals, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert middling, such as perlite, gravel, mineral wool, expanded clay or coconut husk.
verbal description of Methods
The two chief(prenominal) types of hydroponics are 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 each medium, sub-irrigation and top irrigation For any techniques, most hydroponic reservoirs are now built of plastic, barely other materials have been used including concrete, glass, metal, vegetable 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 around the man for food production are the following:
No soil is needed
The water stays in the system and can be reused - thus, lower water costs
It is possible to control the nutrition levels in their entirety - thus, lower nutrition costs
No nutrition contamination is released into the environment because of the controlled system
Stable and high yields
Pests and diseases are easier to get 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 full essay, order it on our website: Orderessay
