FERTILIZER EXPERIMENT OF 1908 



This experiment was intended to be as near a duplicate of the 1907 

 fertilizer test as circumstances would allow. The same land was used, 

 plowing it across the plats late in the autumn of 1907, and replowing 

 in the same manner on the 26th of the following May. The fertilizers 

 were sown after the soil was fitted for seeding. Instead of lime on plats 

 1473 and 1474, marl was sown at the rate of 3000 pounds per acre. 

 The seed was sown on May 28th. A heavy dashing shower the following 

 day caused considerable washing of the soil although the damage was 

 not sufficiently serious to prevent a good stand being secured on* nearly 

 all plats. The plats received thorough cultivation throughout the 

 growing season. At the time of first thinning, June 18th, the fertilized 

 plats looked generally better than the check plats. These differences 

 were still noticeable when the second thinning was finished on July 3rd. 

 By August 24th it was seen that Leaf spot {Cercospora beticola) had
