Yes. And also no. Practices like that are good, but the majority of your carbon sequestration will come in the form of the roots of plants. (This is part of why no till is good.)

Getting surface vegetation to deposit carbon in the soil long term is trickier. You aren't wrong, but it's also not as simple as some folks believe. Just cutting the corn stalks and cobs and leaving them on a field won't put much carbon back in the soil.
