Why add sand?
I thought sand + clay = concrete.
I believe organic material alone will help modify the soil.

Sand + clay will lead to harder soil.
Sand + clay + organic material (rye, buckwheat) will lead to more
workable soil. Organic material must be renewed to maintain soil
fertility.

Hmmm...
Will you need more organic material with the sand?
More than what?

Are you saying sand+organic is better than organic alone as a soil
amendment?
Yes.

So I can improve more soil by adding sand and stretching out my organic
material?

The best garden soil is 30% - 40% sand, 30% - 40% silt, and 20% - 30%
clay. Amend as necessary to approach these numbers. The above should
constitute 90% - 95% of the soil. The other 10% - 5% should be organic
material.
