The cultivation of plants without soil, using
specially prepared solutions of mineral
salts. Beginning in the 1930s, large crops
were grown by hydroponic methods, at first in
California, but since then, in many other
parts of the world. J von Sachs (1832-97)
1860 and W Knop 1865 developed a system of
plant culture in water whereby the relation
of mineral salts to plant growth could be
determined, but it was not until about 1930
that large crops could be grown. The term was
first coined by W F Gericke, a US scientist.
