Hello Richard, and thanks Felix for your reply.
The article concludes by saying “Keep using compost, but don’t add more than an inch or two a year on your landscape plants”.
That is exactly what I recommend, normally two inches for intensive vegetable production, which needs more than landscape plants. This article does not address the difference between ornamental and vegetable gardening.
For compost usage, I don’t see a disagreement here. And animal composts are only one of many I use and recommend.
Well-made compost in my experience hangs on well to it’s nitrogen. If it did not, my crops could not be as leafy and abundant as they are. Including when I have spread the compost in a preceding November, then I still have dark green broccoli leaves and abundant harvests even in the following October.
