General Information:

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/jit/figs-you)

in the fruit of your womb, in the fruit of your livestock, and in the fruit of your ground

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