“…Low soil pH/high soil Al not only physically damages legume roots in the field, but also dramatically reduces the activity and ability of rhizobia to inoculate lucerne roots.

Soil extractable aluminium (Al) concentrations can have a strong impact on the establishment, growth and persistence of pasture legumes. This has become clear in New Zealand high and hill-country, where legumes are scarce and failing to persist in acid soils with high Al levels. For the last decade a research programme has been conducted at Lincoln University focused on legume growth and persistence in acid, high Al concentration soils. Research has examined several aspects of soil acidity and Al toxicity and screened and evaluated a range of legume species, identifying several that show promise in their growth and persistence under acidic and high Al concentrations, in addition to harsh climatic environments. This paper summarises this extensive body of research and also suggests some future research topics for addressing the growing challenge of increasing soil acidity and soil Al faced by increasing numbers of producers.

“…In a 6 year field trial on a high-country Brown soil with CaCl 2 -extractable soil Al levels of 7 ppm (soil pH 5.2), Berenji et al (2017) reported declining lucerne yield (4.2 t DM/ha in Year 1 to 1.0 t DM/ha in Years 4 and 6) and depressed fine root growth. In contrast, the more Al-tolerant Caucasian clover persisted and yielded 1.7 t DM/ha in Year 1 increasing to 4.0 t DM/ha in Year 4 and 7.7 t DM/ha in Year 6.…”

“…High Al concentrations in soil solution adversely affected legume nodulation (Edmeades et al 1991). Berenji et al (2017), in a field trial on a Stony Brown soil in North Canterbury, demonstrated that high 0.02M CaCl 2 -extractable soil Al levels of 15.1 ppm (soil pH 5.2) in the top 75 mm, strongly inhibited the ability of rhizobia to inoculate lucerne; the threshold (above which soil Al has a measurable effect) for effective inoculation was less than 1 ppm 0.02M CaCl 2 -extractable Al. In contrast, Berenji et al (2015) found no effect of a CaCl 2 -extractable soil Al level of 4.2 ppm (soil pH 5.2) on nitrogen fixation in lucerne, on a Gley soil near Lincoln.…”

Soil aluminium toxicity in New Zealand pastoral farming – a review

As most New Zealand pastoral soils are acidic, aluminium (Al) can be present at high concentrations and restrict plant root growth and shoot yield. In field trials, Al toxicity in white clover has been associated with CaCl2-extractable soil Al levels of 3-5 ppm or exchangeable soil KCl-extractable levels of 1-2 me/100g, when soil pH levels were below 5.5-5.7 in the top 75 mm. Lucerne is less tolerant of Al toxicity than white clover and ryegrass, which in turn are less tolerant than Lotus spp., arrow leaf, subterranean, Caucasian, Persian and gland clovers, and naturalised adventive annuals such as cluster, haresfoot, striated and suckling clovers. Soil Al toxicity generally increases with soil depth. Soil pH is a reliable indicator of soil Al and, on average, can be increased by 0.1 units/tonne/ha of applied lime to reduce soil Al to below the toxic range. Lime application is the most effective strategy where it can be ground-applied. A key limitation of ground-applied lime to reduce Al toxicity is that its movement down the soil only occurs slowly except in high rainfall areas. Soil Al and pH levels and legume content in hill soils varies according to slope and aspect and there is an opportunity to differentially apply lime by air to areas with low soil pH and more legume, for the best economic return.
