Looks like we win: 36 to 11

Soil salinity reports for the parcel of the farm which was deep plowed and planted in Barley to encourage rainwater infiltration and salt uptake came in yesterday.  When we began the intervention soil was sampled and tests returned 36 ds/m in electroconductivity.  To put that number in perspective, it is roughly eight times the recommended level for vegetable crops and we were informed that only by irrigating with drinking water could we reasonably expect any productivity.  To put it mildly, the land was highly saturated with salt from the use of saline irrigation water.

The tests recently returned show the amount of salt dropped to 1/3rd its previous level after a single wet season, from 36 to 11ds/m.  This drastic reduction serves as proof of concept for our soil rehabilitation strategy and it bodes very well for next years harvest.
