Question

what is the pH level of earth and rate in ratio​

Answer 1

Answer:

Isotopic evidence has suggested that, although a moderate change in pH (pH 6.7 to 5.2) has little effect on the total rate of N 2 and N 2 O production, the pH adjustment.

Answer 2

Answer:

Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions (H+

or, more precisely, H

3O+

aq) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as 0.01 M CaCl

2), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH < 3.5) and very strongly alkaline soils (pH > 9) are rare
