Gosh I hope not to have written that because animal manure is so much richer in both nutrients and fungi, compared with green waste compost which often has a high content of wood and has been fermented at high temperatures which do not allow fungi to colonise the compost. It still has value but I find it best when used in conjunction with animal manure, a layer of each.
I am doing a trial here with onions grown in cow manure, cow manure and topsoil, and greenwaste compost: all placed on top in six inch layers, grass and weeds below, no cardboard. The first two beds have superb, large onions, while the green waste compost bed has much smaller plants.
Also animal manure does not have to be two years old, personally I think that safety fears are overplayed, because the beneficial bacteria in soil are good at balancing and neutralising any harmful ones. I have used one year old manure, with good results. Any younger than that is not so good because of unrotted litter, slugs and also that nutrients have not stabilised in enough of a composting, decomposing process, so there is more chance of leaching – whereas nutrients in one or two year old manure are mostly water insoluble, yet available to make healthy plants.
