Beating Aluminium Toxicity
When soil pH drops, aluminium becomes more available. A small drop in pH can result in a large increase in available aluminium. Aluminium retards root growth, restricting access to water and nutrients. Poor crop and pasture growth, yield reduction and smaller grain size occur as a result of inadequate water and nutrition.
Pictured above: 1. NO LIME pH: 4.0 – Aluminium: 15 mg/kg, and 2. 1t/ha LIME pH: 5.1 – Aluminium: <2 mg/kg
