But such is not the case. Mr. Root makes but 

 little use of it. He says : " Rye has been my most 

 profitable green manure." 



Harris thought it just as useless to plow in cereal 

 crops for manure, as to attempt to carry buttermilk 

 in a basket. He believed they spilt the most of their 

 nitrogen while growing. Ele has now changed his 

 views. And is conscientious enough to acknowledge, 

 that for twenty-five years he was in error. 



He now writes : " I thought then that wheat, 

 barley, oats, coin and other cereals, during their 

 growth gave off nitrogen into the atmosphere, while 

 clover, peas, beans, vetches, and turnips, retained all 

 the nitrogen they got from the soil and from dews 

 and rains. 



The theory was simple and plausible, and the 

 practical deduction safe and sound. But more recent 

 investigations failed to sustain this view.'' 



CHAPTER XI. 



GREEN Bt/CKWHEAT. 



One ton of green buckwheat contains 8 pounds of 

 nitrogen. 3 pounds of phosphoric acid, and 11 pounds 

 of potash. 



It stands very high as a green manure. Two large 

 crops can be raised in one year to plow in for wheat. 

 In 1875, 1 raised in 51 days 27 tons per acre of green 

 buckwheat. It was sown on the 14th of July, and 

 cut and weighed on the 3rd of September, 



Besides it value as a manure, it will make excellent 

 hay. In July, you should make an estimate of the
