Results of experiments on irrigated meadows, Tackb [Mitt. DetU. Landw. 

 GeseU., 21 [1906), No. 9, pp. 96-101).— The experiments described were Btarted in 

 L900 on meadow lands belonging to the agricultural improvement association of 

 Bruchhausen-Syke-Thedinghausen. 



Three types of soil were selected, a clayey loam meadow with a layer 25 to 30 cm. 

 deep, rich in humus, a low moor, and a light sandy heath. These tracts were subdi- 

 vided and given varying quantities of Thomas phosphate meal and kainit, with and 

 without irrigation. The plats were irrigated by running and still water so as to com- 

 pare the methods. 



The average yield per acre without fertilizers on the first tract was increased 77 

 per cent by irrigating with running water, and 50 per cent by flooding in checks. 

 With the application of a small amount of Thomas phosphate I 150 kg. per hectare 

 annually ) there was a further increase of about 33 per cent, w hile additional quanti- 

 ties showed very small increases in the crop. Kainit alone showed no increaa at 

 all when applied at the rate of about 500 k'_ r . per hectare annually, as the lands were 

 nut deficient in potassium salts. The other tracts -how quite similar results. 



In all cases the method of irrigating with moving water appears to give larger 



yields than the check-ll ling method, averaging on the first tracl 28 percent greater, 



on the second 34 per cent, while on the third the advantage is even more marked. 

 The running water is applied by ridging the land, ami apparently not by furrows as 

 in the United States. The author nine- independent local experiment- and cautions 

 against accepting the data given as applicable under different conditions of soil and 

 ground water. 



Irrigated lands in Idaho ( The State of Idaho. Boise, 1905, /</<. 59 62). A sum- 

 mary of irrigation statistics is presented, showing 3,600 mil.- of canals costing 

 nearly $10,000,000 and covering over 2,000,000 acres, of which 840,000 are no* under 

 cultivation. The publication contains also articles on projects under the Carey Acl 

 and the Reclamation Act, and brief descriptions of irrigation systems by counties. 

 The report is profusely illustrated.
