For saline-sodic soils EC, ESP & pH values are
A. > 4, > 15, > 8.5
B. < 4, < 15, < 8.5
C. > 4, < 15, > 8.5
D. > 4, > 15, > 8.5
Answer: Option D
Solution(By Examveda Team)
Soils that have detrimental levels of neutral soluble salts and a high proportion of sodium ions are classified as saline-sodic soils. Plant growth in these soils can be adversely affected by both excess salts and excess sodium levels.For saline-sodic soils EC value is greater than 4, ESP is greater than 15, & pH values are greater than 8.5.
