the methods used to farm the land are not always beneficial to the
soil in the long term. Agricultural activities are the one of the main
causes of soil degradation.

the most drastic change was in the 18th century when the Agricultural
Revolution saw the manorial system and open field cultivation in
strips replaced. Instead, large scale farming in consolidated units
was introduced, along with the extension of arable farming, intensive
livestock farming and new agricultural techniques such as crop
rotation as well as new crops such as potatoes and improved grasses.
The aim of these changes was to increase agricultural production and
over the following years more technological advances allowed output to
be increased and higher yields to be achieved. In the LEDW change is
relatively slow to happen as a result of the slow development of a
country and a lack of money to effect the changes. However, in the
1960's the Green Revolution allowed developing countries to increase
their output with high yielding varieties of crops such as IR8.

The increased use of inorganic fertilizers is having a negative impact
on the soils, though it is the main reason for increased productivity.
When farmers first used these fertilisers they used ex...
