Module 7 : Soil Pollution

Bulk Density:

Soil bulk density is a measurement of how tightly packed or dense the soil is. It is determined by measuring the weight of dry soil in a unit of volume (g/cm3).

pH: molar [H3O+]= 10-pH; H2O + H2O <=> H2O+ + OH_

Soil pH influences what can grow in the soil and is the product of the kind of parent material, the chemical nature of the rain and other water entering the soil, land management practices,
and the activities of organisms (plants, animals, fungi, protists, and monera) living in the soil.
