Manure or compost tea is the best, but usually you make it yourself because it’s simple. Of course, you need compost or sheepshit.
It’s not normal in my area, mainly because sheep don’t really have a chance around here. I can get why it would be something people would sell and people would buy, but I’m really taken back by the asking price. I’m sure it’s some SHART OF THE DEAL type bullshit, I mean sheep manure, where all you have to do is ask and they’ll give it to you for free or close to it, but still.
The other aspect of this general kind of thing ™, is that while it may be helpful as a fertilizer, it’s usually far from an ideal mix of nutrients for gardening purposes. Like even just looking at the macros (nitrogen, potassium, phosphorus), these things are usually wildly out of proportion compared to what plants actually need. But also, unless you tested your soil to know what it lacks and what it has an over abundance is, like the very best case is that this kind of thing doesn’t make your gardening efforts worse/harder.
Oh this would be great for gardening.
