To give extra context, Finnish runosongs do not mention this, but those from Ingria and Olonets Karelia do (also one collection from North Karelia now that I think of it): First, god of barley Pekko cleared a swidden but left one tree for birds. From there, the fiery kokko bird (also connected to Ilmarinen) set this clearing on fire (this is slash-and-burn agriculture). Then, Osmo (equated with Kaleva) sows barley and, in Ingrian runosongs, also oats. In some versions, Osmo is also the one who brews the first beer but in Finnish runosongs, the brewer is always the feminine Osmotar. I think it's interesting that in spirit of this, the Finnish runosong also describes Osmo's field as being in or near Karelia, it and especially Ingria being plentiful with Osmo-related myths. (From Finland, there is a slice of Karelia first before you can reach Ingria).

Little hop, little tipsiness Was sowed in the ground as vipers Thrown as an enemy To the bank of Osma's field To the top of the meadow of Karelia From there, it rose as string belts Grew with a rope in its armpit / Grew as a rope from the arms?

It seems that the woman addressed at the end is Mielikki. That's a bit weird as she shouldn't have the ability to make anything "rain"... But she is regularly connected to honey. Maybe because it was found in forests? And we know that Päivätär has honey in the heavens so maybe it was thought that it rained down into forests from the heavens?
