138 EXPERIMENT STATION RECORD. 



The plats used in the general fertilizer tests were located on typi- 

 cal old upland soil. The jdelds obtained with different fertilizers lead 

 to the conclusion that a formula consisting of 3^ parts phosphoric acid. 

 1 part potash, and 1 part nitrogen, all in an available form, is the most 

 suitable for middle Georgia conditions. 



Fractional applications of fertilizers have not been found profitable. 



Some native forage plants for alkali soils, A. Nelson {Wi/o})iui(/ 

 Sta. Bid. 4^,j)p. 23-4-5^ Jigs. 12). — This bulletin discusses the forage 

 areas of Wyoming, dividing them into 3 classes — mountain, hill, 

 and plain. The two former areas, being well drained, are reasonably 

 free from alkali. The latter area is divided into normal plains and 

 alkali plains. The native i^lants found upon the alkali plains are 

 described and discussed. These plants are found to have a greater or 

 less value for forage, and it is the object of this bulletin to point out 

 the more valuable ones, and to suggest measures for increasing their 

 3deld. The salt sages are found to be the most suitable for the Wyom- 

 ing lands, and 4 perennials and 3 annuals are illustrated and described. 

 Winter Fat, related to the salt sages, Indian Millet. Slender Wheat 

 grass, and Alkali Meadow grass, are found on the alkali plains and 

 are of value as forage. Tuber Bulrush is found in alkali marshes and 

 is much relished by cattle. These plants are also described. 



Effect of orchards in meadcws, Burki {Landtv. Jahrh. Schweiz. , 

 13 {1899)., 2)2^' 135-151). — Investigations were made b}^ the author to 

 determine what effect on the yield and quality of grass would follow 

 from the growing of orchard trees in meadows. Shade was the chief 

 factor considered. The composition and yield of a large number of 

 species of grass grown both in shade and in sunshine are tabulated. The 

 data show that the first cutting of meadow hay was decreased on the 

 average 32 per cent b}- the shade from the orchard trees, and the second 

 cutting 59 per cent b}' the same cause. The decrease in yield was in gen- 

 eral directly proportional to the nearness together of the orchard trees. 

 Grass grown under fruit trees averaged 0.76 per cent less dry matter 

 and 0.96 per cent less nitrogen-free extract than grass grown in the 

 open sunlight. No marked influence of the shade on the protein con- 

 tent of the grass was observable except where comparatively large 

 amounts of fertilizers were used, and then the protein content was 

 greater in the grass grown in shade. The crude fiber and fat content 

 was slightly higher in the grass grown in the sunshine, while the ash 

 content was somewhat lower. Shade tended to promote the growth of 

 orchard grass and a number of undesirable grasses, and to decrease 

 the growth of French and P>nglish rye grass and red and white clover. 



The produce of old and ne^w varieties of oats, J. Speir {Trans. 

 Highland and Agr. Soc. Scotlaiid. 5. ser., 12 {1899), pj). 225-238). — 

 In 1898, 3 new varieties of cross-bred oats were tested in comparison 

 with the Potato oat, an old variety grown quite extensively' through- 

 out Scotland. The yields o])tain('d from the different varieties were
