GEOLOGIC AGENTS 



Adamson, a. M., 1943, pp. 107-112. (Termite 

 consumption plant remains accelerates 

 formation humus; nest and runway build- 

 ing brings soil above surface and exposes 

 it to weadiering and admixture with 

 humus; promotes aeration, drainage. On 

 the other hand, termites feeding in large 

 numbers may seriously reduce amount of 

 organic matter in soil; harvester ter- 

 mites denude parts of African veldts 

 causing erosion; soil surrounding large 

 mounds may be deficient in calcium 

 owing to accumulation calcium carbonate 

 in mounds.)
