A system of pasturing alfalfa in Salt River Valley, Arizona, R. W. 

 Clothiek (U. S. Dept. Ayr., Office Sec. Circ. 54 (1915), pp. 4). — A system of 

 rotation pasturing of alfalfa in use in Arizona is described. 



One farm is a dairy and stock farm of 160 acres, all in alfalfa. It is divided 

 into 8 fields of 20 acres each. All of these fields are pastured more or less at 

 different times during the year, but occasionally the crop is cut for hay instead 

 of being pastured off. When pastured a field is first opened to dairy cows giving 

 milk. When they have secured the best of the feed they are put into a new field, 

 and dry cows and young stock are turned in to" clean up the feed left by the 

 milch cows. When this has been done all the stock is taken off the field, which 

 is watered and not pastured again until another crop has matured. When a 

 field is cut for hay the crop is put up quickly with a hay loader, and dry 

 cows and young stock are turned in to clean up waste hay. The field is then 

 watered and all stock kept off until another crop is ready to harvest. By 

 this system the farmer keeps the equivalent of 168 full-grown cattle on his 

 farm for 12 months and has 360 tons of surplus feed. This is sold when prices 

 are high and when prices are low it is fed to fattening steers not included in 

 the above enumeration of animals kept on the farm. The stand of alfalfa 

 has been maintained in excellent condition for 10 years. 



On another farm the live stock consists of matured steers and mules. The 

 crop enterprises are the production of alfalfa hay and alfalfa seed. There are 

 140 acres of alfalfa divided into five fields, two of 18 acres each, two of 40 

 acres each, and one of 24 acres. By following the rotation system of pasturing 

 described above these fields were made to furnish 261 days of pasturage to 

 the equivalent of 139 mature cattle, and in addition they produced 247 tons 

 of hay, 10,000 lbs. of alfalfa seed, and 50 tons of alfalfa straw. The farm main- 

 tained the equivalent of 141 full-gi-own animals for 12 months and produced a 

 surplus of hay and seed which sold for $1,860. On this farm the stand of 

 alfalfa is being maintained. 



The associative digestibility of corn silage, cotton-seed meal, and starch in 

 steer rations, P. V. Ewing and C. A. Wells (Georgia Sta. Bui. 115 (1915), pp. 

 269-295, figs. 7). — This bulletin reports the results of a series of investigations 

 to determine the influence of one ingredient of a ration on the digestibility 

 of the other ingredients of the ration. The feeds used were corn silage, cotton- 

 seed meal, and corn starch. Studies were made on nine distinct rations, com-
