I've been thinking about composting in a pit in the ground - is this feasible?
The method of composting that you are describing is called trench composting. In autumn, recycle your kitchen waste by putting it into a trench or pit. Dig a trench one spade wide and one spade deep (approx 30 x 30cm), fill the trench with alternating layers of kitchen waste and garden soil. When full, cover with the remaining soil and leave to settle for one to two months before sowing or planting.
This system is ideal for growing runner beans, peas, courgettes and pumpkins.
