matter cost from $2.50 to $10 per ton. The correspond- 

 ing values of manure would be from 80 cents to over $3. 

 But there is another way of looking at the question. 

 What would the farmer make if he pastured off the clover, 

 or fed the clover hay ? On such a farm, some such crop as 

 clover hay is needed to keep the horses busy at haying time, 

 because the other crops then require little attention. And 

 some sort of animals need to be kept to provide winter work. 



On one such farm, 30 acres of clover were grown in 

 1910. Of this, 10 acres were mowed and plowed under 

 as green manure. 



The cost of green manure crop on 10 acres was : 



Clover seed and seeding $35.00 



Use of land 50.00 



Mowing 7.32 



Total $92.32 



Cost per acre 9:23 



Cost per ton dry matter 8.87
