growing potatoes

[heirloomer08]

I have raised potates for years but this year I had something happen I don't know about. My potatoes tasted really good but the skin looked terrible. It had the thin new skin and the thicker storage skin in bloches all over the potato. If you peeled them you would never know they looked bad. Like I said the taste was great the skin just looked terrible. A friend of mine in town had the same problem but not as bad. Does anybody know what the cause of this is and how to stop it. I really need to get it under control as I have a farmers market and had to be very picky on what potatoes I sold. Anybody's ideas would be great.
Thanks, heirloomer08

Potato Scab can be caused by adding too much manure-based compost to the soil.

and also if you rainfall had been higher than normal during the growing season.
heirloomer2 how much rain do you get per year?

Thanks for the reply's guys!!! It could have been a combination of both compose and rain. As I use manure-based compost and we had almost to much rain this year. I never had to water this year as we had rain just about every week. This would explain in part why my friend in town had it also. The rest of my garden was great, just my potatoes kinda bit the dust, or mud.
