Hi Cody, I use various natural composts that I can harvest directly here at my farm. The best is one that we produce letting our sheep bedding plus chicken litter to rot a full year anaerobically under a hot bed in a trench inside one of the greenhouses. We have an organic vegetable small commercial enterprise which requires large ammounts of organic feeding. Bringing in o.m from outside is too expensive in the quantities we use in our scaling. The sheep are kept in a barn and they get all the regular farm debris added to their beds and thus get well impregnated with urine and faeces. The same for our layer chickens. In use when available that as potting ammendment. However its not always available. Next is leaf mould from our broadleaved trees. Under our poplars huge amounts gather and eventually half rot. This is excellent material too For acid loving bulbs you could alternatively use short pine needle leaf mould too.. Finally if I run out of the previous two, my option is horse manure. I can get that just across my street; its very light and can be used almost fresh. It doesn't cause any inconvenience. In all cases I decide how much I add according to the texture I want to obtain. I prefer it crumbly but , so when squeezed in my hand it holds together. Each compost has different properties so I adjust it by the feel in my hand. I can add up to a third in volume of O.M: I hope I provided the info you were asking for. Arturo ( Bariloche, R.N.
