application of a light dressing of nitrate of soda would pay, except 

 in cases where the soil is already very rich. 



The potash applied, although not benefitting the crop of oats, has 

 evidently had a very important influence in strengthening the catch 

 of clover. Wherever the potash has been applied, there the clover 

 is clearly much stronger than on any of the other plots, not even 

 excepting that where manure has been used. When the importance 

 of clover as a fodder crop and as a means of fixing the free nitrogen 

 of the atmosphere is remembered, the wisdom of using potash as a 

 top dressing when land is seeded with this crop is sufficiently evident.

 Average of the nothing plots : hard corn, 34.2 bushels; stover, 2284 pounds. 



This experiment, voluntarily undertaken by Mr. Clark, was carried
