2013 was my second year as a potato farmer.
Year one I put my seed potatoes too close to the clay base on my property and (I believe) that the watering and rain created a pool around the potatoes and essentially drowned them – 4X8X2 feet raised boxes yielded less than two handfuls of harvest.
This year I made two 4x4 boxes and put the seeds higher up on a bed of good earth - Ozette and purple somethings.
Vigorous growth. Added five layers of boards each 6 inches high. Almost three feet of 4x4 growing area.
Curious harvest. The top layer of both boxes had potatoes. The bottom layer had potatoes. The middle three layers – almost two feet – had zero potatoes.
As the plants grew, did I cover them with new soil too soon? Thus not giving the new root systems to form? Each time the plants got seven inches high I added another layer of 6 inch boards and added dirt leaving about an inch or so of the tops showing.
Cannot think of why I would only have potatoes at the top and bottom of my boxes.
Your thoughts and suggestions are most welcome as I plan the same for 2014.
Thank you.

well if the soil is too dense compact potatoes won't form. they love sandy soft loamy soil that is deep but no more than a couple feet deep. I found potatoes prefer to spread out in this type of soil. I got a huge harvest out of soil that was about a foot and a half deep in an 8 foot by 8 foot bed. still picking potatoes out from last year. they also like the roots to be cool and if it gets too warm this will have a negative effect. too much manure/compost and they get scabby, too much water and they will be hallow or water filled.
