Neighbor is dropping bags of horse manure over the fence.
A/ does or is it best unbagged make a pile and leave it to rot down a bit?

B/I recall no manure in the same bed as carotts. How about compost. The next terrace up test as greater than 7.5 pH. Test kit could be iffy. Same top soil on both. Compost bring it down?

Thanks JB or CC

If you are using the horse manure to grow vegetables, I would suggest piling it up on one of your beds for it to rot down well for 6 months or so.   This will benefit the bed on which it rots down and can then safely be used dug in under plant roots for maximum benefit.   Carrots will tend to fork if sown in a bed previously matured as they seek out the best environment in which to grow, but there should not be a problem using either fresh or mature manure as a mulch.   Carrots generally grow well enough without manure and it benefits other plants such as squash family, brassicas and tomatoes much more.
