The soil of this field is a light loam, about 2 feet deep, with 
a sandy subsoil. 
The duplicate unmanured plots are again very even. Dung, 
at the rate of 20 loads per acre, gave a capital increase, and a still 
larger one resulted from the use of half the quantity of dung 
with 2 cwt. nitrate of soda per acre. Superphosphate used alone 
gave a result below the unmanured, though with nitrate of soda 
added 20 tons of roots were grown to the acre. Sulphate of potash 
added to this last mixture yielded 3 tons more per acre, and its 
addition to superphosphate and sulphate of ammonia was also 
beneficial. Nitrate of soda gave better results than sulphate 
of ammonia. In one experiment suggested by the Norfolk
