SESSIONAL PAPER No. 16 



Thomas' phosplaate, both used singly, also of siiperpliosphate of lime with kainifc and 

 nitrate of soda, and of Thomas' phosphate with kainit and nitrate of soda. 



The land chosen was in a fairly good condition of tilth. The soil was a sandy loam 

 which has been under cultivation since 1887, has been cropped each year with a suitable 

 rotation of crops and has received a dressing of barn-yard manure about once in four 

 years. The last application of manure was in 1897 when it received about 12 tons per 

 acre. 



It is proposed to grow the same crops on tliis land for a series of years, using the 

 same fertilizers in the quantities mentioned every second year. The fertilizers were 

 applied in the spring of 1900 and again in the spring of 1902. 



A large proportion of the pla;ij.s in tlic plots of common red clover died during the 

 winter of 1901-2, and it was thought best to plough them under and resow in the spring 

 of 1902. Most of the plants from the first sowing were destroyed by a severe spring 

 frost, after which the plots were again sown and the plants had made a medium growth 

 before the close of the season. The first sowing of clover was on May 3, the second on 

 May 23, sown in each instance at the rate of 12 lbs. per acre. The second application 

 of fertilizers was made to these plots before the clover seed was sown in the spring.
