although the quantities are not mentioned.) Other experi- 

 ments, also made at Upper and Lower Seehof, but on poorer 

 and riot so moist soil showed that the combination of phos- 

 phoric acid and potash gave in 1896 more than double the yield, and 

 in 1897 six times, and nearly eight times, as much as the un 

 manured land. The best manuring of grass lands was at Goettingen 

 found to be lime, kainit, Thomas phosphate, and nitrate of soda 

 The unmanured was as 100 to 160.6, but Dr. Edler recommends to 

 manure with 5 to 6 cwt. of kainit and 4 to 5 cwt. of Thomas- 

 phosphate per acre as better paying, the increase in such case being 

 as 100 to '139.3. 



Professor Dr. Bardenheuer manured at Lamersdorf in 1892-3 

 his meadows with 4 cwt. Thomas phosphate and 4 cwt. kainit per 

 nibrgen (J acre), and had 21 J cwt. of hay, against 6 cwt. from the 

 "unmanured. Mr. Jans, however, in Eiderstedt, used on his clayey 

 sbil only 2 cwt. of Thomas phosphate with < cwt. kainit, and cut 

 2*3.6 cwt. of hay, against 12.6 cwt. 



One hundred and. twenty-eight. experim.ents.iixLorraine have also j 

 resulted in showing that if Thomas phosphate was used in March 

 or beginning of April (here July or August) the first cut of hav~
