Cracking clay soil poses unique water management problems. Typically, clay soil is presumed to have negligible drainable pore space. Field measurements, however, suggest that there may be as much as 10% drainable pore space available, due in part to soil cracking. Such pore space may be useful in designing irrigation-drainage systems for these soils.
