my question is this, how is hydroden, oxygen, and carbon effected in a clay soil? Most lawns in my area have Alabama clay. Some lawns you can't even get a soil probe in the ground. if a typical composition is 25% water, 25% air, and 45% mineral, how is this effected in a clay soil? Is the 25% air reduced to 15-10% and the water increased to 30-35%?What effect on plants will this have.
