2 GEORGE V., A. 1912 

 Rotation ' 27 



Sheep pasture. 



Crops just as in c S ' save that various mixtures of grain and grass seed are used 

 to test their value for sheep feeding and pasturing. 



Rotation ' A ' Fertilizer. 



Using barn-yard manure only. Four years duration. Roots, grain, hay, hay. 

 Barn-yard manure 15 tons per acre for roots. 



Rotation 'B' Fertilizer. 



Commercial fertilizer but no barn-yard manure. Four years' duration. Roots, 

 grain, hay, hay. Commercial fertilizer: 300 lbs. superphosphate; 75 lbs. muriate of 

 potash; 100 lbs. nitrate of soda, before sowing to roots. Each other year 100 lbs. 

 nitrate of soda only. 



Rotation ( C Fertilizer. 



Half usual dressing ham-yard manure and commercial fertilizer besides. Four 

 years' duration. Roots, grain, hay, hay. Barn-yard manure 7£ tons per acre for roots ; 

 commercial fertilizer at same time, 150 lbs. superphosphate; 37£ lbs. muriate of 

 potash and 50 lbs. nitrate of soda. Besides, 100 lbs. nitrate of soda each year in hay 

 or grain. 



RETURNS PER ACRE. 



To compare results under such varied crop and cultural conditions is a rather 

 difficult matter. The plan adopted has been to place an arbitrary and uniform valua- 

 tion on all products and on pasturing various classes of stock. Following this plan, 

 the returns per acre have been about as follows, the average of six years' work, sav in 

 cases of fertilizers 'A,' ' B ' and ' C,' which are for one year only. 



Rotation ' A.' 

 Average value of crop per annum — $22.79. 



Rotation ' R.' 

 Average value of crop per annum — $23.10 



Rotation ' E.' 

 Average value of crop per annum — $21.04. 



Rotation ' Z.' 

 Average value of crop per annum — $25.43. 



Rotation ' 3.' 

 Average value of crop per annum — $25.59.
