Soil acidification is a natural phenomenon which unfortunately is accelerated by numerous agricultural practices including the application of nitrogen sources containing high rates of ammonium (NH4+) nitrogen . A regular soil sampling and liming program should be central to every fertilizer program to ensure that soil productivity is not limited due to unchecked increases in soil acidity.
South Africa has an abundance of good quality agricultural lime sources which are geographically well distributed and ensure that a responsible lime program is affordable.
