The German
scientists Sachs and Knop demonstrated
that the plants could be cultivated in a
half inert one humidified with nutritious
solution and this gave origin to the nuticultura,
in the following years they were developed
several you formulate basic for the study
of the vegetable nutrition in 1915 Hoagland,
1919 Trelease and it is horn 1925 when
the industry of the hothouses is
interested in the necessity of frequently
changing the earth to avoid problems of structure
fertility and illnesses.
At the beginning
of the thirty W. F. Gericke professor of
the university of California calls to this
system Hydroponic derived word of the words
Greek Hydro water and Ponos Work and this
technique can be defined as the science
of the growth of the plants without using
the floor although using a half inert one
as the gravel, sand, vemiculita, pumice
stone, etc.
W.F. Gericke cultivation vegetables
in hydroponic, demonstrating their utility
and providing foods for the North American
troops parked in the islands incultivables
of the Pacific at the beginning of 1940.
After
the second world war the military ones
continued using the technique and they established
a project of 22 hectares in the island
of Chofu (Japan) to the step of the time
he/she expanded the technique in commercial
plan, and the years 50 ` the countries like
Italy, France, Spain, Germany, Israel, Australia
and Holland that also adopted it.
Presently
with the help of the plastics a great advance
has been given in this technique that has
expanded our horn country and it is from
1994 when Our Association is Born soon
after the interest that he/she woke up the
reading of Editorial Diana's Book Basic hydroponic
written by Gloria Samperio Ruiz and through
the courses and international congresses carried
out by our organization, the number of farming
hydroponic has been increased at different
production levels in Mexico. |
