Improvement of Poor Pasture.

that it is fraught with importance, significance, and suggestive- 

 ness as to the most profitable manner of managing stock on 

 grazing farms. 



Increased Stock Carrying Capacity of Manured Plots. — Apart 

 from any question of the period at which the manures produced 

 their greatest effect on the pastures, and of any change made in 

 their character, the experiments clearly showed that the manures 

 enabled the pasture every year on every one of the manured 

 plots to carry an increased head of sheep stock, varying from 1 1 

 to 33 per cent. 



General Result of the Experiment. — Professor Wright, in the 

 publication from which the above particulars* are taken, dis- 

 cusses various other points of interest which were brought out 

 by the experiment. The general results are summarised in the

All the manures improved the feeding quality of the pastures, 

 just as certainly as they increased their total yield, and this 

 improvement continued for the four years after the application 

 of the manures during which the experiment continued. But
