Abstract: A method and apparatus for building up a ground store of pressed vegetable material wherein the material is picked up by a tractor loader and successively put through a funnel element which carries a store of a retractable plastic sheet hose, whereby a long row of bails are stored in the hose. The funnel element is moved stepwise forwardly by the tractor to consecutively provide the necessary space in the hose for enabling an introduction of the next bail. The tractor and/or loader may be provided with equipment for applying a treating fluid to the bails during the handling thereof, and the bails, thus treated, are stored in a practically sealed manner in the tubular sheet hose.

Abstract: For supplying a desired amount of ammonia to a straw bale, particularly a large round bale, in order to convert the straw material into a feedstuff, the bale is subjected to an ammonia injection treatment in direct association with the bale being reloaded from a local receiving position to a final storing position by a tractor fitted with a suitable bale carrier implement. The bale carrier implement may comprise carrier spears which are provided with injector for supplying the ammonia to the interior of the bales from an ammonia tank carried by the tractor itself.
