guillaume78150 Posted June 13, 2020 Author Share Posted June 13, 2020 Hello Nick, Yes, it's north of Soap Lake, shortly before Columbia River crossing. Strangely, it happens only over plains, mountains are ok. Link to comment Share on other sites More sharing options...
Nick Cooper Posted June 13, 2020 Share Posted June 13, 2020 I don't know what they are, perhaps someone with local knowledge can help you out. Link to comment Share on other sites More sharing options...
John Dow Posted June 13, 2020 Share Posted June 13, 2020 If you zoom right in in Gogle Earth it looks like there's a treatment being applied to the fields, I suspect some might have a plastic cover to protect, others have different crops sown, maybe different fertiliser treatments change the colour as well? If you go to 9/2011 imagery there you'll see most fields are just ploughed with fresh light coloured soil exposed, but some are tinged with green as though the first shoots are poking through.
