XI. — Report on the Field and Feeding Experiments conducted at 
Wohurn on behalf of the Royal Agricultural Society of England 
during the Year 1881. By Dr. AUGUSTUS VoELCKER, F.R.S., 
Consulting Chemist to the Royal Agricultural Society. 
Experiments on the Continuous Growth op Wheat. 
The experiments on the continuous growth of wheat were insti- 
tuted in 1876, and as the tenant grew a crop of wheat in 1875, 
I have now to report the result of the sixth year's continuous 
growth of wheat on the same field. 
Directly after the removal of the wheat-crop of the previous 
season, the land was ploughed shallow, drag-harrowed, and 
thoroughly cleaned, before the seed was sown. Nine pecks of 
Browick wheat were dibbled in on the 22nd and 23rd of 
October, 1880, when the land was in a first-rate condition for 
the reception of the seed-wheat. It appeared above ground on 
the 7 th of November. 
The mineral manures in the quantities given in the tabulated 
results in the following pages were sown on the 22nd of- 
December, 1880, and the salts of ammonia and nitrate of soda, 
diluted with three or four times their bulk of dry sand, were 
sown on the 29th and 30th of March, by a broadcast manure- 
distributor. 
The dung required for the experiments on the continuous 
growth of wheat and barley was made by six bullocks, three 
making dung for the wheat, and three for the barley experi- 
ments. Each bullock received daily 5? lbs. of decorticated 
cotton-cake, 8^ lbs. of Indian corn-meal, 64 lbs. cabbages, and 
lOi lbs. of wheat-straw chaff. They were put into the feeding- 
boxes on the 20th of October, 1880, and in the course of five 
weeks consumed : — 
5 cwts. of decorticated cotton-cake, 
8 cwts. of Indian-corn-meal, 
3 tons of cattle-cabbages, and 
10 cwts. of wheat-straw chaff.
