Oh yeah? Ever made concrete that way? I’ve read that claim for years and assume that it can be done, but any clay can be altered into a silty or sandy soil- it’s just a matter of how much stuff you are willing to add to your clay.
A home grower with clay soil can change the texture of enough soil to nourish a fruit tree by adding sand and I’ve done it. I’ve converted blue potters clay into a good growing medium with large quantities of sand and compost. The thing is that it’s easier to just make raised mounds of a new soil than blending clay with sand and compost.
However, if you incorporate the clay into the mix, your trees will be better anchored and less prone to blowing over. They will also be better able to withstand periods of drought.
But then, a good top soil on top of a heavy soil would accomplish the same thing with less work.
Sandy soils do produce higher brix fruit than clay soils in the humid regions, simply because they hold less available water.
