Planting vegetables in composted steer manure without mixing dirt with it.

Question

Can this be done? I’m thinking tomatoes.

Answer 1

There are gardeners that claim success with growing in pure compost, but a good rule of thumb is about 30 percent compost to your soil.
Your compost may have too much nitrogen and you will end up with lots on nice green plants and no tomatoes on the plant.
