Essay On Hydroponics

Hydroponics is a part of Hydroculture . Hydroculture is the growing of plants in the absence of soil, or an aquatic based environment/medium. Plant nutrients are supplied via water. The word "hydro" is a derivative of a Greek word which means water. And culture is the process involved. So basically Hydroponics is a subset of hydroculture which is a process of growing plants using mineral nutrient solutions, in water that too in the absence of soil.
Terrestrial plants can be grown with their roots in dipped only in mineral nutrient solution, or in an inert medium, like perlite ( Perlite is an amorphous volcanic glass which has a relatively high water content) or gravel.

The earliest known published work on growing terrestrial plants in absence of soil was in the book "Sylva Sylvarum" by Francis Bacon, published a year after his death. After his book water culture became a popular field for

Genetics is an area of science that describes how living organisms, such as plants, inherit their shapes and abilities from their parents. Scientists use genetics select plants that are relatively healthy and are able to bear vegetation under poor conditions. Israel is a good example. Israel has learned to make use of hydroponics and genetics to grow food. Israel has a very dry climate and unfertile soil. They used Hydroponics to help farmers grow crops although the soil was bad and climate was very dry. For water needs, they remove salt from seawater and use that water to grow their crops. The treated water used to be still salty and in less in supply. So, scientists used genetics to look for plants which can grow in small amounts of salty water. Scientists all across the world are continuously looking to use genetics and hydroponics together to help farmers produce food crops that will feed the world’s population in the years
