The highest net profit has been obtained with the use of superphos- 

 phate by itself. Taking wheat at current prices, a steady increase is 

 shown from dressings of li cwt. per acre up to H cwt. per acre — the 

 maximum amount tried. With ^ cwt. super, an increase of 23s. 6d. ]>€r 

 acre was returned after deducting tlie cost of the manure, while with 

 H cwt. per acre it was no less tlian 40s. 



The mixed manures were also responsible for high yields, but the 

 net returns were not so high. At Longerenong the returns were avail- 

 able over a longer period, and show perhaps a truer indication as to the 

 relative values of the manures. 



Manurial Trials ajt Longerenong. 



Each plot was sown with graded Federation seed on the 24th June 

 at the uniform rate of 63 lb. per acre. The cultivation of each plot 

 was identical, but the manurial dressings were different. The results 

 for the seasons 1913 and 1916, together with the average yield of each 

 of the thirteen plots for the past four seasons, are as follow: —
