PROFITABLE FARMING. 33 



The following are a few recorded results on 

 poor heavy land. Returns per acre : 



No Manure gare 15 bus. Wheat and 15 cwt. Straw. 



Dissolved Bones in autumn 



and Nitrate Soda in the 



spring 38 ,, Wheat 23 Straw. 



Again, on an average of twenty years 



No Manure ^ gave 22 bus. Wheat and 1 8 cwt Straw. 



Superphosphate in autumn 



and Nitrate Soda in spring ,, 36 Wheat ,,30 Straw, 



These figures show very conclusively that the 

 clear profit from the increased crop must be 

 considerably more than 150 per cent, on the 

 outlay for fertilisers. 



The Cambridge University Department of 

 Agriculture, in conjunction with the East Suffolk 

 County Education Committee, conducted experi- 

 ments for eight years on poor clay land at Sax- 

 mundham, and in their report, dated October 

 1908, it is stated, " The most useful information 

 these trials give is the wonderful 

 efficacy of phosphatic manures. BO per cent. 

 Superphosphate, compared with no 

 manure, gave a gross return due to 

 the Phosphatic manure of i. gs. per acre, and as 

 this was obtained with a dressing costing less 

 than 8s. per acre, it is highly remunerative. 

 Superphosphate stands at the head of the list/ 1 



Sometimes a second wheat crop is taken 

 without dunging, in which case it is perferable 

 to use a complete fertiliser or a larger quantity 

 of dissolved bones.
