I was digging over a patch of ground yesterday with not a lot growing in it apart from a bit of grass and a lot of weeds in the hope that I could grow my left over potatoes in it. However, as I was digging I could smell diesel in the soil, only in a little area but the soil was definately more grey than usual and was quite oiley. Then I remembered that some diesel was spilt there last year when a open jerry can fell over - about 10 litres!
My question is, although initially covering a small area do you think the diesel will now have been distributed across more ground as its on a slope and the movement of water in the soil may be helping it? Also, I certainly dont intend to grow anything there this year, and as I believe its probably very difficult to get rid of, I just wondered if anybody had had any experiences like this in the past, and if so, could anything ever be safely and succesfully grown there again?
Many thanks.
