Denomination pH range.

Ultra acid < 3.5.

Extremely acid 3.5 - 4.4.

Very strongly acid 4.5 - 5.0.

Strongly acid 5.1 - 5.5.

Moderately acid 5.6 - 6.0.

Slightly acid 6.1 - 6.5.

Neutral 6.6 - 7.3.

Slightly alkaline 7.4 - 7.8.

Moderately alkaline 7.9 - 8.4.

Strongly alkaline 8.5 - 9.0.

Very strongly alkaline > 9.0.

The pH value from 7.0 to 7.5 is considered neutral. pH value over 7.5 is alkaline.

pH value less than 7.0 is acidic.

Soils with a pH of less than 5.5 are considered strongly acidic.

Alkaline soils are characterized by elevated concentrations of exchangeable sodium ion (>15%), free carbonate and bicarbonate, low calcium, high pH value (8.5-10).

There is no term as (acidic soil) used in engineering,

Whether the alkaline soil is the correct answer.

Bharath E said:   9 years ago
Option C is also correct please review.

1-6.9 (Acidic).
7.0 (Neutral).
7+ (alkaline).

Anshul said:   4 years ago
Alkali, or Alkaline, soils are clay soils with high pH (> 8.5).

Bharath E said:   9 years ago
The correct answer is More than 7 pH value is alkaline or basic.

Kapil said:   1 decade ago
Is more than 7 ph value soil acidic or not?

Arun kumar mangalore said:   7 years ago
Yes agree, C is also the correct answer.
