Hello there, I'm wondering. I made a batch of water and grass. Left it too long, it stank most awfully. I removed the grass content and I've had a large container of this liquid for over a month now. Is it still good to use?
I wouldn't use it as-is right now as it's had so long being anaerobic. But if you aerated it with a bubbler for a while and maybe added a bit of good compost to the mix I bet you'd get something that doesn't smell so bad and your plants would enjoy.
i personally wouldn't be too concerned with the foul odor. i'm guessing that batch would work well for your hardier plants. try it on some shrubs at the outer edges of your garden (not too close where someone would complain) and see how it goes.
The question is what are you using it for? I'd imagine it would be a good addition to a compost pile. I wouldn't dump it on a plant I cared about as is. I'd love to hear what happens if you did aerate it.
It sounds like what you have here is akin to stored urine, anaerobic, high nitrogen with no oxygen equals ciliates and other anaerobic loving organisms (which most of these love to eat good bacteria and fungi).
As has been mentioned you need to get oxygen into this liquid, three days of heavy aeration should switch it over to good bacteria production, if you add a bag of good compost to this then you have increased the ability of producing good bacteria growth.
Once you have it going strong, you can use it for watering the soil or you can add it to a working compost heap with no fears of doing harm to what you add it to.
