    A study was conducted to evaluate the effects of Mg on ternary (Na-Ca-Mg) exchange and intern structural stability in prominent Vertisols of TBP (Tungabhadra Project) and UKP (Upper Krishna Project) irrigation commands of Karnataka State, India. Surface soil samples representing typical Vertisols derived from granite-gneiss (Gangavati and Kavadimatti), limestone (Devapur and Islampur) and basalt (Kadliwad and Mannapur) were included in the study. These soils were subjected to equilibration with waters of varying sodium adsorption ratio (SAR-5,20,40,60,80 and 100 millimoles per liter1/2) with different Ca/Mg ratio (4:1,2:1,1:1,1:2and 1:4).Exchangeable Na increased as the Mg/Ca ratio increased from 1:4 to 4:1 indicating that Mg charged waters are more detrimental for structural integrity of the soils. Averaged from all SAR treatments, the Mg-Na systems had between 10.5 to 12.1% more exchan.. View More»
