The warmth of the air and soil tends to the rapid 

 decomposition of these organic matters full of sap 

 which spreads more evenly through the land than 

 any other manure and brings to it a rich provision 

 of nourishment gathered for the most part from the 

 atmosphere. 



Green manure in being transformed in the soil 

 gives rise to such gaseous products, as ammonia, car- 

 bonic acid which can be almost entirely absorbed 

 by the land, whilst the decomposition of nearly all 

 other manures is attended with serious loss. 



These gases retained by the moisture of the land 

 afterwards give nourishment to the plants. 



Green manures are specially advantageous for 

 beets, as they do not burn and do not introduce into 

 the root any excess of matter which might tend to 

 prevent the extraction of sugar. In the interests of 

 the manufacturer, we value the beets grown 

 with green manure at a higher rate than those 

 grown with any other manure. 



Green manure may be advantageously employed 

 in sparsely settled countries, in which there is a 

 great quantity of land at disposal, because it avoids 

 expense in labor and cartage. 



This manure may be also used in conjunction 

 with stable manure ; manure is often spread over 

 the plants before they are buried. 



Green manure produces the same effect as would 

 the manure of a herd of cattle who had consumed 

 three times the amount of fodder.
