Planting was finished on this area on 17th November, 1915. The 

 soil, in which these tests were made at Leongatha, is a grey loam, which 

 is very deficient in phos,phoric acid and potash, as is shown by the 

 analysis.

The following tables give the results obtained in tlie different 

 sections : — 



Section 1. — Manure Tests. 



1. No manure (average of four Sections) 



2. 3 cwt. Super. 



3. 3 cwt. Basic Phosphate 



4. 3 cwt. Blood and Bone 



5. 3 cwt. Potato Manure 



6. 1 cwt. Sulphate of Potash, 3 cwt. Blood and Bone 



7. 1 cwt. Sulphate of Potash, 3 cwt. Super. 



8. 3 cwt. Super., 1 cwt. Sulphate of Potash, 1 cwt. Sulphate 



Ammonia 



9. 3 cwt. Super., I cwt. Sulphate of Potash, 2 cwt. Blood 



10. 6 cwt. Super., \h cwt. Sulphate of Potash, H cwt. Sulphate 



of Ammonia 



11. 9 cwt. Super., 3 cwt. Sulphate of Potash, 3 cwt. Sulphate of 



Ammonia 



In every case an increased weight of the crop was obtained from the 

 application of manures, and the amount of the increase was fairly pro- 

 portionate to the amount of manure applied. Some doubt was expressed 

 at the beginning of the season as to whether the fairly heavy dressings 

 of 9 cwt. and 15 cwt. applied to sub-sections 10 and 11 respectively, 

 would prove profitable. The following table, which expresses the results 

 of these manurial trials in money values, settles this doubt.
