Alright... so I've decided that I want to try some commercial hop production on my 22 acre farm, but obviously this can't be a 'monoculture'. I'm aware of the many drawbacks of pushing out a pile of the same crop.
Growing hops requires a large trellis to support the bines... which is a serious investment. Obviously, underneath the trellis, it's going to be pretty much 'all hops' being grown, or at least as close as possible. Anything else might be a poor use of that investment. The trellis itself will cost about $20,000 and we plan on creating raised beds of soil, and fertilizing with local tested organic compost, ideally.
I would, however, like to throw down some large raised garden beds in between to attract the kind of insect/bird diversity needed to stop things from getting out of control, and also have a bunch of livestock running around in there.
Additionally, right now the land is probably 4 years fallow. It's a hyoooooge pile of brush, long grasses, weeds and other stuff. I am going to need to deal with this in the most intelligent way possible... which might include:
1. Tilling and cover cropping
2. Trying to cover all of this crap with mulch or wood chips.
3. Digging EVERYTHING up and creating large raised beds of good soil... as beds for both the hops and the 'other stuff'.
I am majorly concerned about disrupting the soil ecology, but also know that this is a virtually insurmountable amount of natural foliage/weeds. At the end of the day, I think I need to run across the entire filed with the backhoe, and create long raised beds for everything.
SO....
I guess my questions are:
1. How would you guys deal with the current level of brush in order to prep this thing for use, while preserving soil ecology and making the best use of the organic matter?
2. Do you have any 'permaculture' based recommendations for making the goals of a 'monoculture' type endeavor mesh with the fine threads of sustainable farming? Perhaps plant combinations?
Bonus questions:
3. Is there any downfall to chopping this brush down, so that the field is easier to work with in the mean time? It would be nice to be able to get around on the field. I could actually pile up all of the brush and compost it.
4. I have japanese beetles... anyone successfully deal with these organically?
Thanks for your time and your help guys!
