Manures vsed.—A. 2 cwt. Superphosphate. B. 2 owt. Superphosphate, 1 cwt. Sulphate of Ammonia. 

 C. No manure. D. Same as B, and 1 cwt. Potash Sulpliate. E. Stable manure. 



Kyneton Field. 

 Mr. Argvle, M.L.A., carried out an experiment on the following 

 lines : — 



Mannn>>: iisi/d. — A. ■> cwt. Supeiphosjihate. B. -i cwt. Sujierpliosphate, 1 cwt. I'ntasli .Sulphute. 

 ('. No manure. I). 4 cwt. Lime. E. .Stable manure. 



The yield for all sections was extremelx good, the most noticeable 

 feature being the increase of .section B (superphosphate and potash 

 sulphate) over the unmanured section C. Nearly an extra ton of potatoes 

 per acre for an expenditure of 13s. 6d. is worth consideration, and potato 

 growers with land of a similar class would do well to note the effects 

 of this manurial combination. The stable manure shows need for a 

 supplement of superphos])hate. 



General Review. 

 The date of preparation of the soil, time of planting, and varieties 

 sown, somev.hat complicate the question of potato manuring. Then again
