spot the positive feedback loop?
as the soil becomes more salty, the soil's ability to retain+uptake water is reduced
and so, same plant requires more water to grow
CV problem is complex as it is 1% of US farmland but 8% of production. And the type of the soil is the largest contributing factor
a plan devised:
pump water to saturate the soil to try to wash out the salt
and the leaders of SC thought, well the salton sea is already salty and so the agricultural runoff was dumped in it
