Carrots

My carrot seeds I planted about 3 weeks ago have just started sprouting through the soil.
My plan for carrots is to plant a 2 foot (60cm) row of carrots every 2 to 3 weeks. What I'm hoping to achieve is a continuous supply of carrots during there growing season, which means I'll be planting another row of carrots tomorrow.

From what I've read about carrots they don't like a very fertile soil or else it burns the lead tap root which leads to forking, therefore my carrots are being planted in the bed that had my winter cauliflowers and cabbages.
