GREEN-MANUKES 553 



of greeii-mannring, tliere being a considerable accumulation 

 of stubble and aftermath on the soil. When a rotation of 

 this kind is used, it is better either to supply organic matter 

 in other ways, or to alter or break the rotation in such a man- 

 ner as to admit of a more advantageous use of green-crops. 



Where trucking crops are raised and no very definite rota- 

 tiee is adhered to, green-manuring is easier. It is especially 

 facilitated when cover-crops are grown, as in orchards. Soil- 

 ing operations also favor the easy and profitable use of green- 

 manures. In general, it may be said that the organic matter 

 obtained from such a source should be supplemented by farm- 

 yard manures where possible. A better balanced and richer 

 soil organic matter is more likely to result.
