One vital principle in crop rotation whicli should be held upper- 

 most is often forgotten. The great need of most of our cultivated 

 lands is for more organic matter. The farmer should always re- 

 member that the more often he can turn down heavy sods the 

 greater amount of organic matter he is adding to his land, which 

 means that a short rotation is better for the land than a long rota- 

 tion, unless he is making use of manure or cover crops extensively. 



It is claimed that over two hundred different kinds of plants 

 are grown and marketed in ]^ew York State every year. It would 

 be impossible to give all of this great number a place in some 

 rotation; but, if the farmer will study carefully the suggestions 

 mentioned in this paper, and knows the laws which govern the 

 plants he wishes to grow, he will arrange a rotation best adapted to 

 his conditions and will reap a rich reward for his labors.
