I am a newbie from South Australia and more details are in Introduce Myself.
What I am trying to do is rehabilitate some heavy compacted clay into a family friendly garden. This may not be the right place to post this, so I will apologise in advance.
I do not have money to spend, nor space to compost enough worthwhile matter. The other thing is my small area is completely visible. Google tells me to build a compost heap.... although ideal, not practical.
I have been advised to use gypsum to break the clay, but the cost is prohibitive.
I have access to unlimited racehorse poo. It has very little other matter eg bedding straw, but being racehorses, they are not out to adjistment and their feed is premium and controlled, so there should be no undigested wild seeds.
It is a long slow process digging and weeding the clay (see Intro Self), into which I am digging fresh horse poo. I know it is not ideal, but I don't know how else to get the clay usable. I am also hoping that the fresh horse poo will kill off any weeds and seeds I have missed.
Does anybody know how long it will take for this 'hot' horse poo to be plantable into? I currently intend to plant some grafted dwarf fruit trees, herbs, and a small amount of grass.
Does anybody know how to break up hardened clay? There are patches as hard as concrete!
