Fertility Analysis. 



Available Potash ... 0.0076 



Available Phosphoric Acid ... 0.0165 



Observations. 



This is a lighter soil than the two previous samples and natu- 

 rally more free draining. It is in fair heart, but is low in humus 

 for first class cane land and is almost deficient of carbonate jof 

 lime. 



This soil should receive lime and be helped with green dres- 

 sings, pen manure and any compost or trash available. 



I do not consider that fertilisers would offer any security for 

 a profitable return under present conditions.

Observations. 



This soil consists almost entirely Of fine sand and silt and is 

 naturally porous and free draining. It lacks humus and carbonate 

 of lime. The phosphoric acid and potash are quite satisfactory. 



Lime and vegetable refuse are needed to bring this soil up to a 

 high standard of fertility. I do not recommend commercial fer- 

 tilisers, except I cwt. per acre of sulphate of ammonia to the ra- 

 toons.
