The average. deviation of the routine axial plane from the anatomic axial plane was 5.0Â° abduction (SD =. 2.3Â°). The simplest correction method reduced the mean discrepancy in the observed TT-TG. distance by 68% and 72% in simulated femoral abduction and adduction, respectively.
The sand used to amend some soil is what's called builders sand...you can find it at Home Depot and Lowes and probably other garden centers. It is coarse grain and will provide good drainage....play sand is very fine grain and will cause more troubles than you had before.
Clay soil is heavy, dense and can be dry as hard as a rock if rainfall is scarce. It is the most difficult type of soil to garden in, and it can take a lot of added soil amendments to change the texture of clay soil into rich, friable garden loam. If you add soil amendments every year to your clay soil, the texture eventually will become less dense and more friendly to your garden plants.
