The main advantage Of pot work in testing out fertilizer materials lies in the fact that the conditions under which the experiments are conducted can be to a large extent controlled.
Soil in the same mechanical condition and Of the same chemical composition can be Obtained for a series Of pots with little difficulty. Uniform Conditions Of moisture and temperature can be maintained throughout the growing period, and such disturbing factors as blight, insect pests, and injuries from heavy rain, hail, or high winds can be reduced to a minimum.
