The Christmas and New Year period is that in between time that can either be wasted or used sensibly in deciding what needs doing when weather and ground conditions improve. It’s hard to believe, all going well, that we will be able to spread slurry within a fortnight. We have put into the slurry tanks a biological mix of bacteria and, I see from the label, seaweed and molasses to breakdown the ammonia in the slurry to a less harmful nitrate form.

I have used the product before and it certainly reduces the pungent smell when the slurry is spread, but I would like a fuller explanation of the science behind the product and its effects, as well as more detailed measurement of its effect on earthworms and its actual ammonia emissions.
