By adopting an
adaptive management approach, policymakers acknowledge that their actions may be modified over time as better information becomes
available. Lack of knowledge should not be an excuse for inaction, but the
limits of knowledge and the assumptions underlying actions must
be clearly acknowledged. – Mary C. Watzin
Salinity issues are exacerbated by poor irrigation efficiency.
Improve irrigation efficiency for
effective, efficient salinity management.
More and more, planning and
land stewardship includes cover crops.
Cover crops reduce soil erosion
and increase nutrient-use efficiency.
