46 VERTICAL FARMING 



The farmer, through his good little friends, the " bugs," traps 

 and stores this in his soil, provided he goes about it in a business- 

 like way. 



This way is simple. Prepare the soil for the best content of 

 moisture and air, and see that it is not sour. Be sure that the 

 right bacteria are present, and then grow deep rooted legumes 

 that suit the locality best. Selections of legumes can be made 

 for practically any purpose. Some of them yield the most 

 nutritious hay, while others furnish grain that is good for food 

 for both man and all kinds of farm animals. Others furnish 

 excellent pasture. Some are best suited for soil building in the 

 shape of green manure. 



The deeper the preparation of the soil the better the results 

 that are obtained. A few inches of loose soil will give just so 

 much room for these activities. A few inches more will be of 

 benefit, but the desired production cannot be reached until the 

 air-loving bacteria and the deep-rooted plants have several feet 

 of good mellow soil in which to operate. The only satisfactory 

 method of effecting such deep tillage is by blasting.
