    Ground with good water permeability. The water needs to move through the soil but the soil can't go bone dry. A wet sand is the best ground conditions of all but very very rare.
    Boggy soils are not suitable despite what alot say due to the slow movement of water which means the soil cannot regenerate quick enough. You may get away with it but you run the risk of freezing the ground in a hard winter where you have alot of running hours. You should not extract more than 26w/m2 of ground area and collectors where you have only one loop that runs from example 300m out and 300m back should be avoided as the cooling capacity becomes front loaded in the first 100m of loop.
