In-Depth Information
ENVIRO-GRO
It is an integrated water, salinity, and nitrogen model. It was developed by Pang and
Letey ( 1998 ) .
SWASALT/SWAP
It was a package on an extended version of SWATRE model. The depth and time of
irrigation applied, quality of irrigation water used, soil type and initial soil quality
can be modified and the effects on crop performance, soil salinization and desalin-
ization process, soil water storage (excess/deficit) can be obtained from the model
output.
8.9 Challenges and Needs
Salinity development and salt leaching are interacted by many factors. Evaluation
of traditional concepts such as leaching requirement, leaching fraction, salt balance
concept demands incorporation of a rapid, efficient, and economic way of monitor-
ing changes in salinity during amelioration. New scientific information is needed to
improve the economic gains of salinity amelioration/management because the future
improvements in salinity management seem to be limited by economic rather than
a lack of technological means. In addition to the existing salt-tolerant crop geno-
types, research is needed to seek out or develop genotypes with increased tolerance
to salinity and sodicity.
