Organic Manures 



have been three months in the manure pit. It is 

 sufficient and preferable that it should only have 

 been macerated and have become dark, but not 

 completely black, and that it has been from eight to 

 ten weeks in the pit. In this way the greater part 

 of the hydrocarbonated matter will be left in it, and 

 the humus will not be destroyed by prolonged fer- 

 mentation. 



On a well-managed farm the loss of nitrogen will 

 thus be reduced to a quarter, or less, while the lime, 

 potash, and phosphate will be recovered whole. So 

 obviously there is no excuse for any one who suffers 

 a greater loss than this. Here is the content of 

 fertilising matters in the chief types of farmyard 

 manure : — 



Mixed Manures. 



Mixed manure can be employed on any crops, and 

 an application of 6 to 7 tons to the acre is recom- 

 mended, or from 10 to 12 loads. Root crops 

 require more. A very general practice, particularly 

 on strong land, is to give large dressings at more or 

 less regular intervals, especially on root crops, when 

 they are needed. It would be more practical, how- 

 ever, to give the farmyard manure every year in 

 smaller quantities in association with chemical 

 manures. These heavy dressings are neither 

 useful nor necessary except on land that has been
