Farm statistics in Digitalarkivet

I am tracing my family's immigration from Norway and so far have have had some good luck. My immigrant ancestors' obituaries told us the year of their immigration (1866), and thanks to the Norway-Heritage web site I found them on a ship's passenger list. This gave me the "original" spelling of their surname and a place of residence. Searching Digitalarkivet I found the entry for their gard (farm) in the 1865. They were in Hedmark, in municipality 0415 Løiten. I don't know the Norwegian language, but with a dictionary have been able to translate most of the personal statistics (things like "hans kone" and "gaardbruger od selveger"). I would appreciate anyone's help in deciphering the farm statistics in Digitalarkivet. The column "Sivilstand" contains either "g" or "ug". Can anyone tell me what these abbreviations stand for? Can anyone explain how to interpret the lists of agricultural products? The particular farm I'm looking at lists the following: Stort kveg = 1 Rug = 1/4 Bygg = 3/4 Blandkorn = 1 1/2 Havre = 1 1/2 Poteter = 4 I translated all the words (kveg = cow, rug = rye, etc.) but I don't know what the numbers mean, except that I guess "1 stort kveg" means "1 cow". Any ideas what "1/4" under "Rug" indicates -- amount of land planted, taxes paid, quantitiy harvested -- and what units? My final question concerns the "Merknad (gard)" entry. I translate "Merknad" as "Remarks". For the farm I'm looking at, the entry is "48c". Does this mean something by itself, or is it a reference to other information in the Digitalarkivet? Thanks in advance!
