SCSC 301- Exam 4 with Questions and Answers Given values of soil pH, salt concentration, and % exchangeable sodium, distinguish among nonsaline, nonsodic, saline, saline-soidic, and sodic soils, and describe possible means of reclaiming such soils for crop growth. ANSWER Nonsaline - greater than 8.5 and as high as 9 or above because of sodium being on the exchange site, they hydrolyze into sodium carbonate and sodium bicarbonate in the soil solution. Saline soil vs. non-saline soil - elect...
