If someone hasn’t done tests, they should do. So, results please – what is right?
Trees get water and nutrients from fungi in the soil in layers and turning a double spit before planting will disturb these. Also, the job of replanting after felling is not conducive to digging. For veggies etc., folk want the max. possible growth medium and the fungi do not play a part. For these you do dig and mulch and create a fine loam with air in it. Folk plant carrots to win prizes in 30 foot drainpipes and put their pumpkins on a drip, even get the family in to urinate on them. Lettuces are grown with no soil (hydroponics) and, with cheap heat and light, it could be done in old mines. Indeed, the golden triangle in Yorkshire IS in caves and forces rhubarb. All gardeners will want different things and so do plants. Spreading mixed wildflower seeds over a brownfield site to reinstate the meadows there originally, just won’t work. You need to reinstate the soil type too, not to mention the levels of those pesky worms that dont like working in a post industrial landscape with bits of iron, brick, concrete, glass and rare metals in the soil. So, as with most things, pending the test results, using your common sense seems to be a good idea.
