(b) Lansome Field. 



On the extended area, now consisting of five plots, wheat 

 followed the ploughing-in of the green crops, 5 cwt. of basic slag 

 and 1 cwt. of sulphate of potash per acre having been previously 

 (1921) given to these crops. "Red Standard" wheat — 2\ bushels 

 to the acre — was drilled on all the plots on October 25th, 1922. 

 Throughout the period of growth the crop looked better on the 

 tares plots than on the mustard ones, and these appearances were 

 borne out at harvest. The crop was cut August 14th, stacked 

 August 21st, and threshed November 12th, 1923. 



The results were : — 



The differences in weight of corn are but small, but the tares 

 have, in each case, given appreciably more straw, and the general 

 tendency is to confirm the results in Stackyard Field. At the 

 same time, the crops are unaccountably small, and, following on 

 work carried out with these soils in the Pot-culture Station, it 

 was decided to lime one-half of each series in Lansome Field and 

 Stackyard Field, and to see whether the small crops obtained 

 might not be due to the poverty of the soils in lime. 



1924. 

 Lime, as contemplated above, was given to one-half of all 

 the plots on September 25th, 1923, at the rate of 2 tons per acre. 

 Tares — 2 bushels per acre — were sown on March 29th, 1924, and 

 mustard — 20 lb. per acre — on May 29th. The green crops were 

 decidedly better on the new plots than on the old ones. They 

 were ploughed in on July 31st and second crops sown on August 

 19th, these being, in turn, ploughed in "green, September 26th-30th, 

 and wheat sown. 



5. Malting Barley Experiments. 

 1923. 



The field chosen was Butt Close, a light sandy loam. The 

 area used had previously carried a moderate crop of swedes, to 

 which farmyard manure had been given. 



The barley was drilled on April 10th at the rate of 2£ bushels 

 per acre, the manures being put on the same day. The barley 

 came up nicely and promised to be an excellent crop. Early in 

 June the control, plot 1, looked a bit patchy, while plot 5 (no 

 nitrogen) was much less vigorous than plots 2, 3 and 4. These 

 appearances continued until July. The crop was cut and shocked 

 August 30th-31st. Pots 2 — 5 were all dead ripe. Plot 1 had a 

 fair proportion of green or only partially ripe straw.
