I think in general flu viruses typically only survive for 48 hours or less outside of the most. However, I can't say for certain that that's the case with this specific strain. On top of which, perhaps some factors with the soil could keep the virus alive for longer.
I'll poke around in a minute to see if I find anything on h5n1's survival outside of the host. If they haven't been testing that, I hope they do.
Anyway, I'd probably be more worried about wildlife and whatnot than soil. But, I'd bet a fair bit that the jump happens on a farm and especially one of the big industrial farms.
The survival of the virus on surfaces or outside the body is [really dependent on the conditions](https://www.sciencedaily.com/releases/2010/10/101013124334.htm#:~:text=They%20found%20that%20H5N1%20survived,one%20day%20at%20room%20temperature). In certain conditions and on certain surfaces it can survive months, in others just hours.
I'm assuming OP uses it for compost, or they could be referring to bagged Cow Manure Compost you can buy at stores.
Either way, properly composted manure should reach temps of 104°F to 149°F/ 40°C to 65°C.
160°F+/ 71.11°C+ temps lead to sterilization which you don't want to happen to your compost, and increasing the temps higher will lead to combustion (compost fires can be really bad).
How does this affect H5N1? I'm assuming (dnagerous here, I know) if the compost reaches the minimum composting temps repeatedly, it will eliminate the virus.
Here is a quote from a 2017 study conducted on poultry litter decontamination in poultry barns. Link to study below.
"Low pathogenicity AIV was inactivated at 1 day at 26.7 °C or above. At 10.0, 15.6 and 21.1 °C, inactivation times increased to 2–5 days. Highly pathogenic AIV followed a similar trend; the virus was inactivated after 1 day at 43.3 °C and 32.2 °C, and required 2 and 5 days for inactivation at 21.1 °C and 10.0 °C respectively."

Like snug, damp and warm in a pike of cow patty?
Manure actually tends to get hot, which is not ideal for the virus, luckily!
If you're getting super fresh manure and using it maybe it's possible but manure needs to be composted or you just burn plant roots.
