I would say that if the plants you are wanting to use this strawy compost with are high nitrogen users like lettuce or corn, they will need some good nitrogen available...as it takes N to finish rotting the straw.

I find that in warm and moist soils that the straw disappears quickly if worked into the soil. I think that if you give a bit of time to finish rotting in the soil before planting, it works well.

If that straw is still readily distinguished then that compost is not finished. You can use it, as is, as a mulch but not a planting medium.

I tried it once. Thought the straw would never break down. Love it as mulch on veg garden, though.
