Von Seelhorst and Fresenius (1904) conducted experiments in the 

 weighable lysimeters at Gottingen, Germany, which have already been 

 described. Four tanks were used. Tanks 1, 2, and 3 were planted to 

 oats, and tank 3 was also seeded to clover. A crop of clover was harvested 

 in October. Tank 4 was planted to beets. All the tanks were planted 

 in April and the drainage records were run for nearly a year from that 

 time, so that they compare fairly well in that respect with the results 

 recorded here. The soil was a loam. The loss of recorded bases in the 

 drainage water for the eleven-months period, calculated to pounds per 

 acre, was as follows: 



Hanamann (1898) reports experiments with lysimeters holding 50 

 kilograms of soil, of which some were planted and some were bare. The 

 period during which drainage water was collected was only from April 1 

 to October 30 of one year. Obviously the annual removal of bases cannot 

 be ascertained from this. Maize, barley, and red clover were raised in 

 different lysimeters on the same type of soil, which was used also in 

 a lysimeter that was kept bare. All the bases were leached in greater 

 quantities from the bare soil than from the planted tanks. 



One of the few lysimeter experiments in which lime was applied to 

 the soil was conducted by Tacke, Immendorff, and Minssen (1898), 

 who used small quantities of muck soil. They found that only after 

 repeated applications of lime was the solubility of the potassium of the 

 soil increased, but application of potassium salts increased to a marked 

 degree the solubility of the soil calcium. Increased amounts of calcium 

 were not found in the drainage water following the application of lime. 

 A considerable proportion of the potassium applied in fertilizers passed 

 thru in the drainage water. 



At the Hawaiian Sugar Planters' Experiment Station, experiments with 

 lysimeters holding 250 pounds of soil were conducted by Eckart (1903). 

 To different tanks lime was applied in the form of (1) burnt lime, at
