Moses speaks to the Israelites as if they were one man, so the words "you" and "your" here are singular. (See: rc://en/ta/man/translate/figs-you)

in the fruit of your body, in the fruit of your cattle, in the fruit of your ground

This is an idiom. See how you translated these words in Deuteronomy 28:4. AT: "with children, animals, and crops" (See: rc://en/ta/man/translate/figs-idiom)
