A South Australian woman who helped her son conceal the murder and burial of his partner has been jailed for six-and-a-half years.

Margaret Archer appeared in the District Court on Thursday after earlier pleading guilty to helping her son Neil Archer conceal the murder of 20-year-old Jody Meyers.

Ms Meyers' body was found under a concrete slab in a shed in the backyard of Margaret Archer's home a month after she went missing in 2015.

Neil Archer strangled Ms Meyers following a heated argument sparked by his concerns her family was trying to break them up.

He took her body to his parents' home near Mannum, east of Adelaide, and buried it under the floor of a toolshed before returning the next day to cover the grave with fresh concrete.

After his arrest, he pleaded guilty to murder and was jailed for a minimum of 22 years.

In helping her son, Margaret Archer used Ms Meyers' bank card to withdraw $250 from her account to buy concrete to cover the dead woman's grave.

Judge Paul Muscat said her offending was at the higher end of the scale for the offence of assisting in a crime.

"Plainly all of your actions were considered, calculated and deliberate," Judge Muscat told the 57-year-old in sentencing.

He said Archer was "deceitful in the cruellest of ways" in giving the family of Ms Meyers false hope that she was still alive.

The judge set a non-parole period of four years
