To ensure environmental, economic, and social
sustainability, farmers must adopt different farm-level practices such as judicious use of chemicals, integrated
pest management, adequate irrigation, and proper care of
plant and animal health. Especially, the relationship
between pest sellers and farmers behavior about the
proper use of pesticides is very important. In a research
conducted by Aktas (2001), the place of pest sellers in the
agricultural extension system was investigated and it was
found that at the macro level there is a lack of law and
regulations, which will direct the optimal use of chemicals
and pesticides. Soil pollution in the locality is basically
caused by improper use of farm machinery, improper use
of chemical fertilizers and pesticides, improper irrigation
and lack of modern irrigation systems such as trickle and
drip irrigation, deforestation, early and excessive gazing
of range lands, and farm land being used for housing and
industrialization purposes.
