The author is speaking as if Abimelech literally took salt and sowed it as seed that would grow up from the ground. He means that Abimelech scattered salt all over the ruins of Shechem the way people in this culture scattered seed that they were planting. If it would be clearer in your language, you could state the meaning plainly. Alternate translation: [and scattered salt all over it]

וַ⁠יִּזְרָעֶ֖⁠הָ מֶֽלַח

(Some words not found in UHB: and,Abimelech fought against,city all the=day (the)=that and,he_captured DOM the=city and=DOM the,people which/who [was]_in,it killed and,he_pulled_down DOM the=city and,he,sowed_it salt )

Scattering salt all over the ruins of Shechem was a symbolic action. Abimelech did this to express the wish that the city would always be an uninhabited wasteland, like a salt desert. It was as if he was saying, “May no one ever live here again.” If it would be helpful to your readers, you could explain the significance of this action. Alternate translation: [and sowed it with salt to express the wish that it would always be an uninhabited wasteland]
