IPA: //ˈraɪzəˌpleɪn//
KK: /raɪˈzoʊpleɪn/
The area around the surface of plant roots where soil and microorganisms interact.
The rhizoplane is crucial for nutrient absorption in plants.
Rhizoplane is formed from "rhizo-" (from Greek "rhiza", meaning root) and "plane" (from Latin "planus", meaning flat or level). The term refers to the flat surface of the soil that is in contact with the roots of plants.
Think of 'roots' ('rhizo-') and a 'flat surface' ('plane') where those roots grow — that's what rhizoplane means.
