I am not certain about the bloom in Finland but there are place here where 60 hives to a yard is pretty much standard operating procedure. .
That research was from Australia.
But if it standard, you keep your hives in 50 hives punch.
We have a standard 10 hives in one place. That same figure was 80 years ago and still valid figure.
Problem is that pastures have changed totally and hives are 4 times bigger than 80 years ago.
It is same with rape. 50 years ago standard was 4 hives per hectar and it is still the same and hives are 3 times bigge now.
Australian have critical attitude against those "standards". I just told my opinion and you keep those 50 hives in one punch and get 100 kg per hive. I wonder how you get 5000 kg honey from one point.
But your average yields are far from 100 kg or even 100 poundshttp://outdoorplace.org/beekeeping/honey1.htm
Honey production in 2004 from producers with five or more colonies
totaled 184 million pounds, up 1 percent from 2003. There were 2.56
million colonies producing honey in 2004, down 2 percent from 2003. Yield per colony averaged 71.8 pounds, up 3 percent from the 69.9 pounds
in 2003. But do beekeepers tell the truth about their yields
. Not at least in my country. The truth for tax collectors is something. No one can earn his living with such figures.
How many hives ... I have not calculated.
In eastern Europe hives have vanished but they have not been calculated ever.
