Bizzell the soil received in being transferred to the lysimeters, altho it was not allowed to become air-dry, which always greatly increases the quantity of soluble plant nutrients in a soil. The average yields of crops on these tanks for each of the years of the experiment are given in table 15. The yield for each tank is given in table 1 of the appendix (page 92). If moisture were a limiting factor in the production of these crops, it may be assumed that the fact would be indicated by a diminished flow of drainage water from the tanks producing the largest crops.

In figure 6 are shown the yields of dry matter in the maize crops on tanks 3, 5, 7, 9, 11, and 12 in 1910, and also the quantities of drainage water in liters from the same tanks for the period beginning May 1, 1910, and ending April 30, 1911, when the moisture content of each tank would have returned to its capillary capacity. In figure 7 are shown the total yields of dry matter in the five crops raised on each of tanks 3, 5, 7, 9, 11, and 12, and also the quantities of drainage 34.
