388 The Wohurn Field Experiments, 1911. 



particularly the case where corn crops, such as wheat and 

 barley, had been grown year after year on the same land. 



Whereas the season of 1910 was marked by an almost sunless 

 summer, in 1911 there were almost nothing but sun and heat 

 from May to September. 



The rainfall at Woburn for the entire year amounted to only 

 19'24: in., as against the 2t)*82 in. recorded in 1910. In April 

 there were eleven rainy days ; in May, ten : in Jiine, eleven ; 

 in July, three ; and in August, ten ; the rainfall for these five 

 months reaching, in all, only 5*23 in., whereas in the corres- 

 ponding months of 1910 the total rainfall was 10'37 in. In 

 the month of July, 1911, only "37 in. of rain fell, and in 

 August "99 in. 



Such a season as that of 1911 was in one way beneficial, 

 even on light land, inasmuch as it gave excellent opportunities 

 for cleaning the land. The hay crop, though short, was of 

 excellent quality, and was exceptionally well " saved," though, 

 subsequently, the pastures presented a brown and " burnt-up " 

 appearance. 



By means of early sowing, and then by keeping the land 

 constantly stirred, and thus obtaining a fine tilth, fair crops of 

 mangold and sugar-beet were obtained, but other root crops 

 suffered greatly. 



Continuous Growing of Wheat {Stackyard Field) 

 1911 (35th Season). 



No alteration in the system of manuring was made during 

 this season, the small dressing of 5 cwt. per acre of lime on 

 plot 2aa given in 1910 not being repeated. 



The land was ploughed September 21-30, 1910. Farmyard 

 manure (giving 100 lb. ammonia per acre, as ascertained by 

 actual analysis) was ploughed in on plot lib on September 29. 

 Wheat, " Square Head's Master," at the rate of 9 pecks per acre, 

 was drilled on all the plots on October 15, mineral manures 

 being applied on the same day to the different plots that were 

 to receive them. 



The wheat came up very well, and, early in the next year 

 (1911), the farmyard manure plot (lib) looked decidedly the 

 best. 



There was some frost early in February, and snow about 

 March 14. The winter, however, was of an open character. 



On March 9, rape dust was applied to plot 10b and sulphate 

 of potash to plot 11a. Already at this period a difference, not 

 noticed before, had l)egun to show itself between the plots 3 

 and 6, the former, which had not received any mineral manure, 

 looking decidedly the darker and stronger. The top-dressings 

 of nitrogenous manures were applied, the first halves on May 2,
