Abstract
THE growth of plants in liquid media instead of in soil is a method that has been much used in laboratory work for many years. For experimental purposes the method has the great advantage of permitting close control of environmental conditions and of food supply, to a degree that is impossible when soil is used. For some purposes the combination of nutrient solution with an inert substratum, such as sand, forms a useful modification. Much of the conclusive work on the importance of 'trace' elements in the economy of plants could scarcely have been carried out without the use of water culture methods.
