TECHNOLOGIES MODERN TECHNOLOGIES OF DRIP IRRIGATION AS THEY ARE TODAY

Abstract

The advantages and disadvantages of subsurface drip irrigation (SDI) as compared to alternative irrigation systems are conceptually discussed. Each category (advantages and disadvantages) is subdivided into three groups: 1) Water and soil issues; 2) Cropping and cultural practices, and 3) System infrastructure issues.  The adaptation and adoption of SDI systems into diverse cropping systems, geographical regions, soils and climate depends, to a large extent, on how potential advantages are balanced against potential disadvantages. In some cases, just a few advantages are expressed for a given cropping system, but are expressed so strongly that they provide a good counterbalance to the potential disadvantages.  Future research and development will probably add to the list of potential advantages while addressing and reducing the disadvantages. However, this current listing can be used to devise and adapt other possible uses for SDI. Specific examples of SDI use in maize (Zea mays L.), alfalfa (Medicago sativa), almonds (Prunis dulcis), cantaloupe (C. melo) and wastewater applications are discussed with respect to balancing advantages and disadvantages.
