SUMMARY

Two calcitic limestones, one dolomitic limestone and a basic slag were compared in pot tests with wheat. The amounts of amendment used corresponded to 1.5, 2.0 and 2.5 exchangeable aluminium and also to increase pH up to 6.5. In all cases exchangeable aluminium was completely neutralized. For the smallest amount of amendment (1.5 x AD, dolomitic limestone was inferior to the others. For amounts larger than 2.0 x Al, basic slag was superior to the other amendments in increasing wheat production.
