Chirality? You mean, of organic molecules?

Plants make their own organic molecules. They're not fungi, slurping them up from the soil.

Micronutrients, as the term is used in agriculture, means specific chemical elements that are needed in lesser amounts than the primary nutrients (N, P, K) and the secondary nutrients (Ca, Mg, S). Micronutrients are B, Cu, Fe, Cl, Mn, Mo, and Zn.

Soil structure is of course important, but that doesn't have anything to do with micronutrients.
