For some years now, governments, researchers and farmers
have become increasingly conscious of the important role Precision
Agriculture (PA) will play in the near future. With the current projections
of expected world population growth and the subsequent
decrease of available land and natural resources, there will be a
pressing need for a cheaper, more efficient and environmentally
friendly agriculture (Srinivasan, 2006). PA seeks to avoid applying
the same management practices to a crop regardless of site conditions
and may be used to improve field management from several
perspectives; for example, it can help to minimize the wastage of
pesticides required for the effective control of weeds, diseases and
pests and to ensure that crops receive adequate nutrients, leading
to more efficient and greener agriculture (Kropff et al., 1997; Earl
etal.,1996).
