Soils have a natural characteristic called the cation exchange capacity (CEC) that allows them to hold (and exchange) cations (e.g., Ca+2 or Na+). These cations are held tight enough on the CEC that ...

Soils affected by salts can be described in two ways: by salinity classification or by potential crop response (Figure 1). Salinity classifications are based on the total accumulation of salts in the ...

Saltwater intrusion from sea level rise and tidal flooding is increasing soil salinity risks in coastal farm fields (Figure 1). Soil salinity is related to the presence of soluble salts and cations ...

The soil is formed when rocks are broken down by the action of wind, water and climate. The characteristic features of a soil depend upon the rocks from which it has been formed and the kind of plants ...
