This paper attacked the problem of whether or not the health of plants was determined by the dissolved solids of the water from which they were grown.

In Germany in 1860, botanist Julius von Sachs published the first noted nutrient solution formula. In 1865, Wilhelm Knop, a German agricultural chemist, formed another nutrient solution. In the years 1900-1920, scientists extended the established number of elements that made a successful nutrient solution from six to ten. Hydroponic experiments were becoming more successful with these new elements. In the 1920s William F. Gericke termed this method “hydroponics.” Researchers began to realize ho... |
