Soil is used in agriculture where it serves
as the primary nutrient base for plants
However, as demonstrated by hydroponics
it is not essential to plant growth
if the soil-contained nutrients
can be dissolved in a solution
Hydroponics is a method of growing plants
using mineral nutrient solutions
in water without soil
Terrestrial plants may be grown with their roots
in the mineral nutrient solution only
or in an inert medium such as perlite
gravel, mineral wool, or merely a coconut husk.
Why then crave for ecological green food
when one can eat black and brown mud
as the primary nutrient base for plants
