Autor: Yvon Cavaloc, Laurent Wantiez, Simon Gensous, Hamid Amir

Publikováno v: Journal of Soil Science and Plant Nutrition
Journal of Soil Science and Plant Nutrition, Sociedad Chilena de la Ciencia del Suelo, 2021, 21 (4), pp.3544-3554. ⟨10.1007/s42729-021-00626-6⟩

Arbuscular mycorrhizal fungi (AMF) are generally involved in the adaptation of native plants to ultramafic soils, especially in New Caledonia. These soils are deficient in major elements, particularly in phosphorus (P), and are rich in potentially to
