HOOS FIELD 



Barley 



The experiments on the continuous growth of barley were begun in 

 the Hoos field in 1852. The arrangement of the plots and the manures 

 applied to each plot have practically been unchanged since, so that the 

 plots to-day show the effects of more than sixty years' continuous growth 

 of barley under the same treatment year after year. There are four 

 longitudinal strips receiving different combinations of the mineral 

 these are all crossed by four breadths receiving different nitro- 



manures ;
