that combines conventional aquaculture‚ raising aquatic animals such as snails‚ fish‚ crayfish or prawns in tanks‚ with hydroponics cultivating plants in water in a symbiotic environment. In normal aquaculture‚ excretions from the animals being raised can accumulate in the water‚ increasing toxicity. In an aquaponic system‚ water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria into nitrates and nitrites‚ which are utilized

RESEARCH: Hydroponics is a subset of hydroculture and is a way of growing plants using mineral nutrient solutions‚ using just water. Researchers discovered in the 18th century that plants absorb mineral nutrients as inorganic ions in water. Normally soil is thought to be required for plant growth‚ but in actuality‚ soil is not needed at all. When the mineral nutrients in the soil dissolve in water‚ plant roots have the ability to absorb them. When the required mineral nutrients are introduced

Intensive farming is a way of producing vast amounts of crops by using numerous chemicals and machines. These practices include growing high-yield crops‚ using fertilisers‚ pesticides and keeping animals indoors. Food production is increased however there are various advantages and disadvantages of this particular method. An example of this method would be conventional chicken farming. This method may be used by farmers due to predators e.g. foxes killing their free range chickens‚ minimising their

conventional agriculture and hydroponics as well as the preparation methods of steaming and microwaving can be seen to impact on the nutritional value of food. It can also be understood that there is a direct relationship between the development of chronic health conditions and the nutritional status of food. Conventional agriculture involves industrialized growing‚ producing the most amount of food on less land. In contrast‚ an alternative method of farming is hydroponics. This involves the cultivation

This essay will describe six solutions for the environment and social problems‚ and demonstrate that land management‚ reducing car use and using hydroponics or aeroponic technology are more effective way to confront these issues. Climate change‚ which is caused by motorization and urban sprawl‚ is one of the most significant problems. Urban sprawl results in more energy use in transportation‚ and

Simon points out that "the capacity of food-factory production has expanded to a degree almost beyond belief." (Simon‚ p. 115). He describes how hydroponic farming‚ which involves indoor‚ factory-controlled conditions‚ is more land efficient and produces higher quality produce than traditional farming methods. He also argues that our food supplies are not limited by the amount of sunlight falling on
