It was also conventionally farmed arable land before, alternating between wheat and rapeseed. Good soil, but quite compacted due to the large tractors, low in earthworms, but that changes surprisingly quickly with the right gardening approach. It is already teeming well under our lawn. However, lawn is a nitrogen eater times ten, so working with a bit of MNSP fertilizer is only beneficial. But not before May! - Before we sowed the grass, I worked the land once with a Rheinische field hoe, which is real exercise, but it brings a lot of air into the soil. So it lay fallow the first winter. In spring 18, it was hoed again, then rototilled, and then sown, only lightly raked in, not rolled. Keep it nicely moist, great lawn, it reached rolled lawn standard. K.
