Question: CEC values for organic soils lie in the range of
Options:
3 – 5 meq/100 g
10 – 20 meq/100 g
20 – 50 meq/100 g
50 – 100 meq/100 g
✅Explanation:
-Organic soils (or histosols) are characterized by their high organic matter content. Organic matter has a very high cation exchange capacity (CEC) due to the presence of numerous functional groups (like carboxyl and phenolic groups) that can hold and exchange cations.
-The CEC of organic soils typically ranges from 50 to 100 meq/100g or even higher, depending on the type and degree of decomposition of the organic matter.
