Soils of Azamgarh, U.P. have been found to fix copper fairly in good amounts. The fixation is found to be endothermic and is accompanied by a decrease in the resultant pH. The fixation is more with loam soils and generally increases with the depth of soil. pH, sesquioxide, magnesium oxide, exchangeable magnesium and C/N ratio have been found to affect the fixation. Copper is fixed as Cu(OH) + in the acid systems.
