Table 9.1 indicates that 97.2% (volume basis) of the world water is in oceans and seas. Freshwater accounts for merely 2.8% of the total volume, o

Moreover, essential biological activities can also be prevented hindering good fertility in the soil. All these will ultimately result in a decli

This involves chemical reactions and processes between various components and particularly focuses on investigating the fate of contaminants and nutrients within soils. For example, weathering and adsorption by the s

Soil minerals can be formed from in situ or local rocks and are called authigenic. They can also be transported from a different parent rock distance away and are called detrital in origin.

It was mainly used for soil survey but modifications with time also made it an important means of communication for the discipline of soil science in agriculture, forestry and engineering to predict soil behaviour under defined use and management or manipulation.
