In what type of soil is magnesium more mobile?

Magnesium mobility in soils is influenced by several factors, including soil texture. Coarse-textured soils, typically characterized by larger particle sizes such as sand and silt, have greater pore spaces between the particles. This structure allows for improved water movement and, consequently, the movement of soluble nutrients like magnesium within the soil profile.

In coarse-textured soils, the larger voids facilitate better drainage and reduce the likelihood of nutrient retention compared to clay-dominant soils, which retain moisture and nutrients more effectively due to their smaller particle size and higher surface area. Likewise, highly compacted soils can hinder water movement and nutrient transport, while soils with high organic matter typically bind nutrients more tightly, affecting their mobility.

Therefore, magnesium is more mobile in coarse-textured soils due to the ability of these soils to allow for efficient drainage and nutrient transport, promoting a higher level of magnesium availability for plant uptake.
