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 .

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.
