I've found in the soils I have around here, loamy topsoil, with clay, no real heavy, but has some gravel, well drained, holds moisture etc., that fall plowing, gardens and larger food plots is that I seem to get a good kill of any grasses, and with some secondary tillage in spring, in addition to plowing in the fall, it seems I can really delay or keep weeds at bay. They'll show up eventually, but if you mulch with dry grass, (I dry it then use it like hay), shade out with whatever you are growing, it just seems better when the soil is turned over in the fall. I also think that making sure the plow is doing a neat, uniform job and turning the sod, or soil or what have you completely over, will give the best results as I stated above. If it does not do a good job, whatever is left showing will come back as if nothing was done.
For the most part the soils are similar around here, to my ground, though lower, flatter areas and fields don't seem to have all that glacial till with round rock. I mention that because, most farmers, do not fall plow here, and there is a lot of ground that is corn on corn, year after year. We have rolling hills, some steep ones, so erosion in those areas would be a concern, but flat areas it does not seem to be an issue, now if things dry out, wind could take some of the lighter soils, I've cleared areas with a nice layer of black topsoil, from years of vegetation growing, brush, small trees etc., if you turn that finer loamy top layer up, and it dries enough, you could lose some of that with wind erosion, but usually it stays wet or moist enough to stay put, then a snow pack, so there might be some risk in some conditions, just what I've observed. I noticed these soils in areas that were not used for many years, once cleared, I am careful not to go too deep and turn up clay and mix that in, have to keep an eye on the depth.
Not sure where in NJ, I am familiar with soils there from rich sandy topsoils to clay/loam like here and similar from having been a heavy equipment operator on quite a few job sites from northen NJ to ocean county, monmouth county etc.
