Having taken on an allotment on a site that was very nearly derelict, I'm just getting ready for my first growing season. One thing I'm not quite sure how to manage is the soil conditioning.
The soil is heavy, with poor drainage and a pH of about 6. It seems to have had mostly weeds (and the odd tree) in it for a while, so we're starting pretty much from scratch.
We plan on using a four-season crop rotation, and would like to grow as close to organically as we can productively.
The recommendations seem to be to use lime to raise the pH and break down the clay, and manure to lighten the soil, but we can't do both at the same time, so that's a little confusing. Also confusing is the wide range of fertilisers available (bonemeal; fish, blood, and bone; hoof and horn; seaweed; etc.). Comfrey and leaf-mould seem like they should be part of the long-term mix too, but I'm not quite sure how and when they fit in.
Basically, I'm baffled and winging it, and need a clearer plan. What would be the best approach, short-term and long-term, to bringing the soil back into working condition?
