Soil and Water Mitigation

Measures applied that significantly reduce the amount of potential soil erosion and sedimentation from resource management activities

Soil fertility

The potential of the soil to supply nutrient elements in the quantity, form, and proportion required to support optimum plant growth.

Soil Reaction

The degree of acidity or alkalinity of the soil mass expressed in pH values or in words as follows:

          - extremely acid, below 4.5;

          - very strongly acid, 4.5-5.0;... read more

Soil salinity

Measurement of the quantity of mineral salts found in a soil. Many semi-arid and arid areas are naturally salty. By definition they are areas of substantial water deficit where evapotranspiration... read more
