EXPERBIENTAL STATIONS — REPOKT FOR 1880. 



has produced the best crop on the station. We should naturally 

 expect that those plots which had borne light crops in previous 

 seasons would be less exhausted than others, and show this by 

 bearing relatively heavier crops when the manuring was dis- 

 continued, and this is shown markedly on plot 15, whose nitrogen 

 had been supplied from shoddy, a very insoluble and therefore 

 slowly acting form of nitrogenous manure. It had hitherto 

 been one of the w^orst plots on the station, and this year it is 

 one of the best. A similar compensatory action is noticed 

 uniformly among the phosphate plots where hitherto those with 

 dissolved phospjhates produced the best crops. It will be seen 

 by the subjoined table that the plots with undissolved phosphates 

 have now the best of it : — 



Undissolved Phosphates. 



The plots which had formerly received undissolved phosphates 

 have produced about 5 per cent, more dry matter per acre than 

 the others, and the hay is of superior equality, containing a small 

 percentage of ash and woody fibre, and therefore yielding about 

 10 per cent, more actual food. The best of these plots is the 

 one which has hitherto been the worst — viz., 5, which received
