Carrot seeds seem to sprout and dry up way too fast for me. I find that carrots are really hard to start in new sheet mulch too.

Precisely. That is why I have had my best results on loose soil, AND covering with a board. The board prohibits the quick drying out, and allows them to get their feet into soil. Mulch (nor compost) is not a growing medium for germinating seeds. While compost may have some nutrients, there are not enough available nutrients to allow a tiny seed to grow through even a thin layer into soil. By law, compost cannot be marketed as a fertilizer, but can be marketed as an amendment: the nutrients are too variable, and of inconsequential amounts. Tiny seeds need to get their feet into real soils, as they cannot store enough energy for a long fight for survival.
