Land Degradation: Agricultural Soil Pollution
10
Overgrazing : occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods
Overcropping : to exhaust the fertility of land by continuous cultivation of crops
Deforestation : is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use
Erosion : is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations
Soil acidification : is a process by which soil pH decreases over time, and there are often no visible signs of the problem.
Soil alkalinity : is associated with the presence of sodium carbonate or washing soda in the soil,either as a result of natural weathering of the soil particles or brought in by irrigation or flood water
Soil salinity : is the salt content in the soil; the process of increasing the salt content is known as salinization.
Desertification : is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife
Slash and burn : is an agricultural technique which involves cutting and burning of forests or woodlands to create fields
Pesticides : are substances or mixture of substances intended for preventing, destroying, repelling or mitigating any pest
