EXPERIMENTAL FARMS 



1-2 EDWARD VII., A. 1902 



No. 5. In reddish lumps, easily broken. Not unlike sample No. 1, but not showing 

 any root fibre. 



The samples for analysis were made on the ' fine earth ' prepared by first removing 

 all fibre and pebbles and then grinding and seiving the remainder. In the determina- 

 tion of the ' total ' constituents, hydrochloric acid, specific gravity 1 -115, was used as 

 a solvent, digesting the soil for 10 hours at the temperature of the water-bath. For 

 the estimation of the ' available ' potash, phosphoric acid, and lime, 1 per cent solu- 

 tion of citric acid was employed, digesting in the cold for 5 hours with frequent agi- 

 tation.

 Kesults calculated on water-free Soils. 



The data in the subjoined table have been furnished by Professor Ganong. They 

 give the proportions of the various soil-forming constituents in the example under in- 

 vestigation.
