•2. The artificial manure used in tlie first ease slioiild contain 

 a fair amount of nitrogen, as witliout it ])otli tlie yii'M will l.r 

 low and the berrv small. Sulphate of ammonia is a Ix'ttcr 

 barley manure than nitrate of soda, giving erjual yield and 

 generally superior quality. The quantity used should not Iw 

 more than 1\ cwt. per acre. Rape cake up to .') cwt. per acre is 

 also a good source of nitrogen for the barley crop. 



3. Barley is particularly dependent on a free supply of 

 phosphoric acid, 3 cwt. of superphosphate per acre may br 

 profitably used on most soils, especially where the climate is 

 wet. Even with, barley after roots superphosphate is valualde. 

 hastening the ripening and making the sample more uniform. 



4. An artificial supply of potash is rarely likely to be 

 wanted, except on dry sands and gravels and in dry seasons.
