HOOS FIELD— LEGUMINOUS PLOTS 



1848-9 ONWARDS 



The small plots (see Plan on page 40) represent portions of the 

 original plots on which attempts have been made to grow leguminous 

 plants continuously since 1848. Various combinations of mineral manures 

 have been used up till 1898, but after the first few years very small crops 

 have been grown, and the clovers in particular generally fail. After 

 fallowing in 1903 to clean the plots, they were resown as before in 

 1904. 



The remainder of the area was formerly occupied by similar small 

 plots of the same leguminous plants. These were ploughed up in 1898, 

 and five crops of wheat were taken without manure in order to test the 

 amount of nitrogen accumulated by the leguminous crop and left in the 

 soil. 



In 1904 black tartarian oats were sown, and in the oats, lucerne, red 

 clover, and alsike clover were sown on three strips ; a fourth strip, fallowed 

 in 1904, was sown with vetches in October of that year, as shown in the 

 Plan on page 40. The new plots run across the old ones at right angles. 

 The following table shows the crop obtained in 1905 and each year since 

 to 1912 inclusive.

HOOS FIELD— POTATO PLOTS 



Residue of Manures 



On ten plots potatoes were grown with various manures for 26 years 

 (1876-1901). In 1902 the manuring was discontinued and barley sown. 

 Table XX. shows the yields obtained.
