To clarify, we "have to" hay (or sometimes just mow down the grass) until we can afford animals. Once we can afford animals we won't be haying anymore. And why we need to mow/hay, we have a huge amount of wetland, ponds, lakes around the area, that are not necessarily healthy and definitely lack biodiversity, and so there is a lack of beneficial insects and predators of biting bugs. I will be remedying this as well. The amount of biting bugs are so great that we cannot go outside without full bug jackets and being fully covered and there is no time of day when we are not attacked. Not so nice when we have hard work to do and its hot outside. What doesn't help is that my children and I cannot use bug dope (my children even react to citronella but I found that is ineffective here anyhow). And I've tried every natural alternative on the web, we even own a mosquito magnet. We find that keeping the grass down helps keep the bugs at a distance as the house is mainly surrounded by pasture. It's a matter of survival until we get the farm up and working which will not be for quite a few years. This is why the ground needs to be somewhat level, so we can safely run a tractor across it.
Good point, haying is not fallow. It was fallow last year: we didn't have time to mow it down. The soil is good, and I love the clay, we never have to water. But the low permeability needs to be addressed a bit, we have a lot of run off and that wetness stays for days, if not longer, on the surface. We need it to permeate a little faster. That's what I mean by the clay needs to be addressed.
As I mentioned before we plan on buying/renting a deep plow (subsoil plow, yeomans plow, whatever you prefer to call it) to not only address the clay, but because the past owners ruin the ground they created wet areas in every ditch, depression, tire track, etc that they made: thus adding to the mosquito and no-see-um population. However, I'll be able to build a natural swimming pond without a problem here
I've spent 4 years now looking at everything on this farm and addressing the issues holistically. That's why we are cleaning the slate, the previous owners were so ignorant of nature and her processes, that they did everything wrong (and I mean everything) which has caused so many serious issues that it's too numerous to talk about on this forum. And I know people will ask "well why did you buy the farm", it was literally "live here or die" what would you choose?
So this is where we are and as I've said, my only issue is trying to mitigate the unlevelness with the least amount of damage and resources. Would just using a deep plow level the ground? I've never used a deep plow before so I have no reference to draw from and I cannot find any mention of this on the web. Or would we have to use a deep plow and a light harrowing? I don't know. That's why I'm here asking you veterans.
Thanks again for all you input, I really do appreciate the help.
