The Lois Weedon Plan of Groicing Wheat. 589 



In the following table are given the results of this experiment, 

 obtained in the season 1855-6 just passed. For the sake of com- 

 parison, there is first given, in the upper portion of the table, the 

 average annual result for the four previous years, of the " one seed" 

 of the " tioo seed^"" and of the " drilled common fallow'''' plots ; and 

 also the average for the same years, of the continuously unmanured 

 plot in the adjoining field. And, in the lower portion of the table, 

 is given the produce at the last harvest (1856), in the adjoining 

 field (where wheat is grown year after year without or with similar 

 manures successively), of the continuously unmanured plot, and of 

 the plots having the same manures as those now applied to the 

 Lois Weedon plots. The manuring of the plots was, per acre, 

 as under: — 



1. Unmanured. 



2. Mineral Manures only. 



300 lbs. sulphate of potash. 

 200 „ „ soda. 



100 ,, ,, magnesia. 



200 „ calcined bone. \ 



150 „ sulphuric acid (brown), j" 



3. Ammonia Salts only. 



200 lbs. sulphate of ammonia. 

 200 ,, muriate of ammonia. 



4. Minerals and Ammoniacal Salts. 



300 lbs. sulphate of potash. 



200 „ „ soda. 



100 „ „ magnesia. 



200 ,, calcined bone. \ 



150 ,, sulpburic acid (brown). / 



200 ,, sulphate of ammonia. 



200 ,, muriate of ammonia. 



Looking at the middle division of the table, which shows the 

 effects of manures, 6cc., on the trenched and forked land, and also 

 the produce on the common fallow portion, it must be borne in 

 mind that, in point of fact, rather more than half of the former 

 was fallow, and less than half of it under crop, in the previous year ; 

 ;md that, moreover, smaller amounts of proiluce had been taken 

 from this than from the common faih)w portion during tlie four 

 previous years. In comparing, therefore, the produce now ol)- 

 tained by thicker sowing, manure, &c., on this land with that on 

 the common fallow plot, we nmst remember that the former was 

 also in rfrcat part fallowed, and that the whole of it was less 

 exhausted by jirevious croj)ping than the common fdlow portion. 

 Keej)lng tills In mind, It Is seen that the unmanured, trcnclied, 

 and j);ut-fallow jjortion, gave within a bushel as nuich corn, and 

 actually a few pounds more straw and more total produce than the
