Manganese deficiency causes marsh spot in pea. This disorder is prevalent in which type of soil?

Solution(By Examveda Team)

Manganese deficiency causes marsh spots in pea. This disorder is prevalent in alkaline soils.
The soils with Marsh Spot contained less salt-soluble manganese than those on which peas were free from the disease, but this relation depended essentially on the contrast between acid and alkaline soils.
Mn serves as a cofactor and a catalyst in various metabolic processes in different cell compartments, such as the oxygen-evolving complex of photosystem II (PSII) or reactive oxygen species scavenging.
