ROTATION 



the only reason he has for buying chemical 

 fertilizers. 



This shows the importance of leguminous 

 crops to the farm. They supply this nitrogen 

 at almost no cost, or at a profit. 



Some plants have more power than others to 

 use the contents of the subsoil, and may draw 

 less on the upper soil, and further, by their 

 decay may add richness to the earth. Most 

 legumes have this power to take nourishment 

 from the subsoil. 



Well-planned rotation helps to maintain the 

 supply of decayed stuff in the soil, on which 

 the plants feed. It also improves the soil's 

 texture. Moreover, it not only lessens the 

 necessity for much chemical fertilizer, but it 

 puts those fertilizers to better use. Where 

 live stock is kept, crops should be raised to 

 feed the stock to make manure. 



Rotation is, also, a plan for cleaning the soil. 

 Different weeds and insects grow after different 

 crops and the succession or "rotation" as we 

 call it, prevents any kind getting a secure hold. 



It enables the farmer to meet the demands 

 of the market, by continuous crops.
