A fertile lime-rich soil with dark humus above a pale soft calcareous layer, typical of grassland on chalk or limestone.
- ‘R. triquetrus was collected from a chalk rendzina soil under grassland in the Chiltern Hills, Oxfordshire.’
- ‘La Romanée also has a notably steep slope with less clay and more rendzina in the make-up of the soil.’
- ‘The soil consisted of a rendzina 28 cm in thickness, overlying a horizon that has been altered by cryoturbation and was situated on a gelifracted chalk layer.’
