WebMar 1, 2013 · Inhibition of Nodulation by Low pH Conditions. Legumes species differ in their nodulation and growth response to acidic soil. 22, 24, 56 Generally, nodule formation is more sensitive to soil acidity than other aspects of plant growth. 22 Species, such as M. sativa, are highly sensitive to acidic growth conditions, whereas others, including Lotus tenuis, are … Soil pH is a measure of the acidity or basicity ... Al 3+ is most soluble at low pH; above pH 5.0, there is little Al in soluble form in most soils. Aluminium is not a plant nutrient, and as such, is not actively taken up by the plants, but enters plant roots passively through osmosis. See more Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. See more The pH of a natural soil depends on the mineral composition of the parent material of the soil, and the weathering reactions undergone by that parent material. In warm, humid … See more Strongly alkaline soils are sodic and dispersive, with slow infiltration, low hydraulic conductivity and poor available water capacity.
