years without the use of fertilizers or 

 manures, providing they have constant 

 iillage. 



Effects of Bacteria. 



The microorganisms of the soil also 

 play a most important role. In general, 

 the richer the soil, the larger the num- 

 ber of microorganisms found. Tillage 

 stimulates bacterial activity, and the 

 various modifications which these in- 

 numerable small soil organisms bring 

 about in the soil are exceedingly com- 

 plex and understood only in a general 

 way. It is known that they decompose 

 various substances in the soil; that 

 some of them accomplish nitrogen fixa- 

 tion, some denitrification, and others are 

 nitrifying organisms. Besides the 

 presence of a large bacterial flora in 

 soils, the number of bacteria sometimes 

 exceeding millions to the cubic centi- 

 meter, numerous forms of fungi may be 

 found, besides algse and various types 

 of active animal life. In a medium 

 containing such a vast number of differ- 

 ent types of organisms much antagonism 

 and a severe struggle for existence 

 necessarily exist. It is also known that 

 many chemical substances, such as for- 

 malin, carbon bisulphide, etc., affect the 

 organisms in the soil and also act as a 

 general stimulus to plants. Volatile 

 chemical substances have a direct stimu- 

 lative effect on the crops and in some 

 cases probably improve soil conditions 

 by destroying antagonistic species. In 

 the same way soil sterilization produces 

 exceptionally fine crops. Soils, however, 

 differ so greatly in different localities 

 that while some are greatly benefited by 

 steaming, others are affected unfavor- 

 ably by this process. It is known that 

 the process of steaming soils to 212 

 degrees Fahrenheit greatly modifies 

 their chemical composition, and in some 

 cases produces toxic substances which 

 act injuriously to the crop. Russell and 

 Darbishire found that crops obtain three 

 times as much nitrogen and twice as 

 much phosphoric acid and potash from 

 steamed as from unsteamed soil. Steam- 

 ing has a similar effect to aeration, from 

 the fact that an exchange of gases 

 takes place. 



Chemical Proces^ses. 



As previously stated, the chemical 

 processes in soils are extremely complex 

 and what may prove beneficial as a 

 fertilizer in one soil may not in an- 

 other; therefore, many of the fertilizer

experiments conducted here and there 

 are contradictory. It is often possible 

 to grow good crops with fertilizers for 

 a few years, but later it becomes im- 

 possible to grow the same crops success- 

 fully in these soils, indicating that 

 some change of an injurious nature has 

 taken place. 



During the last decade various trou 

 bles arising from soil toxicity or over 

 feeding, resulting' in a malformed crop, 

 have been on the increase both in the 

 greenhouse and in the field. The symp 

 toms of malnutrition differ in different 

 species of plants. Sometimes the roots
