Contributions of the Mechanical Fractions of the Soil and its Organic Matter towards Potash fixation

Abstract

Perhaps the first use of the world "fixation" was in reference to nitrogen, following the famous discovery: of Hellriegel and Willfarth. Fixation was later on applied to immobilization of phosphorus by soil. Now the importance of potash-fixation on the lines of nitrogen and phosphate-fixation has been fully appreciated and investigated. Accordingly the phenomenon of potash-fixation was studied on our soils.
