Gardening.
If you garden without fertilizers, and compost garden waste, then you are capturing carbon in the soil. If you use a composting toilet too, you capture even more.
If you compost only the garden waste, and only( spread that compost on your garden, then the amount of stored carbon won't increase much, because a lot of what goes into your compost must have come from the soil. But if you also compost food-waste, and if you add soil-conditioners such as farmyard manure, then the amount of stored carbon will increase steadily.
But as has been noted up-comment, the easiest, cheapest way to get carbon into the ground is to not dig it up in the first place.
