I love both, but mainly use the preps and cowpat prep in the last 20 mins of stirring. However nettle and comfrey teas are a great support and feed for hungry plants in my garden. Just been talking with a farmer about the help to pastures when spraying horn manure onto a field where the animals have just grazed. It is also amazing to see pasture react after cutting hay or silage when sprayed with Horn Manure. Love to hear from anyone doing it how it works from them.
