Drainage of agricultural land is one of the most critical water management tools for
the sustainability of productive cropping systems, as frequently this sustainability
is extremely dependent on the control of waterlogging and soil salinization in the
rootzone of most crops. On some agricultural lands, the natural drainage is sufficient
to maintain high productivity. However, many others require improvements in surface
and subsurface drainage in order to optimize land productivity, while maintaining the
quality of soil resources. As time passes, drainage requirements may change because of
changes in the general socio-economic conditions, such as input and output prices, and
more intensive crop rotations.
