The Norfolk System, as it is now known, rotates crops so that different crops are planted with the result that different kinds and quantities of nutrients are taken from the soil as the plants grow.
Norfolk systemet, som det nu er kendt som, roterer afgrøder således, at forskellige afgrøder beplantes med det resultat, at forskellige typer og mængder af næringstoffer optages af planter fra jorden, når de vokser.
