Soil Science is devoted to the broader outlook of the entire field of soil fertility. 



Articles dealing with the more important facts, observations, deductions and problems of 

 soil biology, soil chemistry, and soil physics are published. 



Papers devoted to plant physiology, agronomy, bacteriology, or geology, are accepted for 

 publication if they contribute directly to the knowledge of soil fertility. 



The study of the mineral and organic constituents of soils, soil gases, soil water as a sol- 

 vent of soil material, soil colloids, the transformation of commercial plant foods in soils, 

 questions that deal with the fundamental facts of soil fertility and productivity, are given 

 due consideration. 



The phenomena concerning soil micro-organisms, such as bacteria, molds, protozoa, and 

 algae, receive careful attention.
