Linear relationships between shoot magnesium and calcium concentrations among angiosperm species are associated with cell wall chemistry.

abstract：BACKGROUND:Phosphorus (P), iron (Fe) and zinc (Zn) are essential elements for plant growth and development, but their availability in soil is often limited. Intercropping contributes to increased P, Fe and Zn uptake and thereby increases yield and improves grain nutritional quality and ultimately human health. A better...
