Question

I need a description of pegasse soil with reference to the following: profile, PH, structure, water/moisture content, and texture.

Answer 1

Soil texture is a classification instrument used both in the field and laboratory to determine soil classes based on their physical texture. Soil texture can be determined using qualitative methods such as texture by feel, and quantitative methods such as the hydrometer method.


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 soilshave a pH above 7. Ultra-acidic soils (pH < 3.5) and very strongly alkaline soils (pH > 9) are rare
