Voor een akkerbouwer of tuinder is het belangrijk de zuurgraad van de grond te weten. De meeste planten groeien het beste bij een pH-waarde tussen 5 en 6.5. De juiste zuurgraad is voor iedere grond echter verschillend: Voor zandgrond dient de zuurgraad zwak te zijn: tussen 5,5-6.0 omdat de grond anders slecht voedingsstoffen opneemt.
