The absorption of potassium and phosphate ions by typical soils of the Connecticut Valley

Bogue, Robert Herman 01 January 1915 (has links) (PDF)
It has been known for a long tine that soils possessed the rover of taking up or absorbing certain salts from a solution, and a large amount of work has confirmed the fact that soils. show a selective power of absorption towards the different ions in the solution. (1) Thus in general the positive ion is absorbed to a greater the extent than the negative, consequently leaving the soil solution in the idle condition. This one formerly explained as a simple mathematical reaction,- The bases of the soil and of its solution interchanging, or as the hydrogen of tho complex organic acids known as humic acids being replaced by the base of the salt in the solution. That there Is more or less interchange among, the bases is easily shown by analysis to be true, but it has been repeatedly proven that the base liberated by the soil is usually not nearly equivalent to the base absorbed from the solution. (2) Although the acidity of the resulting soil solution may be explained by the former hypothesis as being due to the formation of on acid or an acid salt t yet it entirely fails to explain the latter JV.ct of non equivalent metathesis.
