Our basic upper elevation for frost depth is -50 cm.

Hello, I am attaching an example image regarding the frost depth. For example, in an area with 50 cm frost depth, if we accept the ground level as 0, should our base upper level be at -50 cm? It is easier to understand what I mean in the image, I will be happy if you answer, good work everyone

If the frost depth is 50 cm, the bottom level of the foundation must be buried 50 cm into the soil. The logic in the depth of frost may cause settlements in the foundation due to the changes that will occur in the volume of the soil under the foundation when it freezes and thaws. For this reason, when the bottom level of the foundation is below the frost depth, you will have fulfilled the frost depth requirement.

Yes

Is not 0.2 m - 1.0 m vegetative soil layer? In my opinion, the level called -0.30 can cause problems in terms of carrying capacity.

When the ground safety stress is given, it is already given according to the ground level. The bearing capacity of the vegetable soil or embankment is already considered 0. In this respect, the foundation is not determined only by looking at the frost depth.
