" Bone Feetilizek." 



As regards bone fertilizer, a reference to last season's figures (see this 

 Journal, lOth January, 1916) shows a lower guarantee in phosphoric 

 acid, citrate soluble, but a higher guarantee in nitrogen. The analyses 

 of collected samples in 1914-15 were much higher in the percentage of 

 nitrogen and citrate soluble phosphoric acid. The average price paid 

 per ton for bone fertilizer in 1914-15 was £5 18s. 7d., against £5 15s. 6d. 

 in 1915-16. The average value of collected samples in 1914-15 was 

 £5 8s., whereas this season it is £4 9s. 5d., and the average guaranteed 

 value was £4 15s. 9d. in the former year, as against £4 8s. in 1915-16. 



Three samples of special or mixed manures were collected. All were 

 found to analyze up to guarantee. In the case of barley manure, the 

 price charged was £5 10s., the value on analysis £5 8s. 8d., whilst the 

 guaranteed value was £5 6s. 9d. per ton.
