FARM CROPS 



ROTATION AND STABILITY 



One crop following another also enables the 

 farmer to better employ his labor, his tools and his 

 teams ; it checks the spread and ravages of insects 

 and diseases. A single crop may fail or be low in 

 price, but of several crops 

 one or more is likely to be 

 in greater demand or higher 

 in price. 



And now we come to 

 humus. So many of our 

 soils need it. There is little 

 hope of making them highly 

 productive until hiimus is 

 put into them again. The 

 growing of cultivated crops 

 like corn or cotton deterio- 

 rates the soil, not only be- 

 cause plant food is taken 

 out or washed away, and the 

 physical condition of the 

 soil injured, but also because 

 the vegetable matter is used 

 up. All kinds of stubble and 

 weeds, clover roots, stable 

 manure and green manure 

 are needed to supply the ex- 

 hausted vegetable matter, 

 and bring the soils back to 

 the productive condition that they were in before 

 the plant food and humus were drawn out. 



WHAT THE TILLER MUST DO 



If, then, land is to be made rich and kept rich, 

 the tiller must keep these things in mind: He must 



MEADOW FESCUE AND

 for pasture and hay. Tliey 

 are specially desirable In 

 permanent pastures, as 

 both are of long duration. 

 Both are well known in 

 the South and in the semi- 

 arid regions. The bromo 

 grass is being used to re- 

 place the common Buffalo 

 grass of the prairies.
