the turnips shown in the pictures with the discoloration in the centres is definitely Boron deficiency. It cannot be cured but can be prevented by spraying Borax on the ground (one ounce in 2 gallons of water sprayed over 50-60 square yards before the seeds of brassicas are sown) Purist organic growers do not subscribe to this measure. Boron is part of the soil as much as Phosphates or Potassium. This problem is far more widespread and unresolved than almost any other single problem and I am delighted to see it raised.

put simply there is a shortage of the element Boron (a trace element) in this soil and you cannot grow brassicas (turnips and cabbages in this soil successfully unless you add some Boron.
you are welcome to come back again with another question if you do not understand what i am getting at.

i have left an answer to this problem in irish gardeners forum. Don't be too upset over this as other non brassicas can be grown without changing the soil or without applying chemicals.
