Research update for ameliorating subsoil acidity using organic amendments locations
Aims

A range of organic amendments have been tested to assess their effectiveness on ameliorating soil acidity in the field. The crop yield was monitored over three years from 2018 to 2020.

Key messages

Lime increased soil pH and decreased the exchangeable aluminium percentage (Alex%) significantly.
• Organic amendments could be used to ameliorate soil acidity, but they were not as effective as lime.
• Crops responded more to nutrient addition than amelioration of soil acidity with organic amendments in the short term.
• The long-term effect of organic amendments on soil acidity and crop yield response needs further investigation.
