I manage a few hundred acre farm and we actually just took “sustainable” out of our marketing. We direct retail meat that we raise. Sustainable has become trendy yet hard to define.
When people ask me what it means to be sustainable I say first of all our farm needs to be financially sustainable so we can maintain this land.
If we are talking about environmental sustainability we turned corn ground into pasture which helps carbon sequestration. But managing pastures is tough and it does require use of a barn so they dont become quagmires. Which means nutrient management becomes difficult when the cattle and sheep are inside for long periods of time.
I’m hoping to be able to put up a monoslope barn and utilize a bedded pack with sawdust made from ground up pallets. Much easier to control run off!
My horse lives out with the cows or sheep most of the year but again making hay requires a lot of fuel. Though I would agree that most hay is very low input and I wouldn’t seek out organic hay specifically.
I actually dont use much that’s labelled organic but that can be another thread! Interesting topic!
