screenings, as a comparison of effectiveness of different kinds of liming 

 materials. The effectiveness is shown in the accompanying table. Com- 

 parison of standard Michigan fertilizers was made on these wheat 

 projects. The applications of fertilizers are to continue through the 

 next four years. 



RESULTS OF LIME TESTS 



S. acid=8lightly acid; M. acid=niedium acid. 



In the Thumb area and Saginaw Valley twenty-two sugar beet projects 

 were established. The objects being to determine the rate and kind of 

 fertilizers and methods of application, special emphasis is made on the 

 amounts of phosphate and potash. The fertilizers were applied with 

 the seed, over the seed, under the seed and on each side of the row and 

 broadcasted and worked in before planting. 



During the year samples were taken of alfalfa on various fields under
