Treatment of subsurface acidity - wheat trial 2004 (established 2003) locations
Aims

To test a suitable relatively quick and cost-effective method of ameliorating subsurface acidity.

Key messages

Before attempting subsurface lime incorporation it is essential that the pH of the profile be known. The amelioration treatments were no larger than the effect of the ripping.
