Soil acidification is a natural process, hastened by modern intensive agricultural practices, which may negatively affect crop yield via reduced nutrient availability. Soil acidification in agriculture is traditionally managed by applying lime to target soil pH ranges that optimise nutrient availability. However, yield depression can occur with recommended rates of liming in certain soil types.
My research seeks to understand the underlying physiological mechanisms behind this negative growth response in legume crops (peas and beans). With this knowledge we can develop novel methods that help mitigate this response, thus helping to restore the beneficial effects of liming in susceptible soils.
