Nitrogen and phosphorus availability have stronger effects on gross and net nitrogen mineralisation than wheat rhizodeposition
Published 2022Soil nitrogen (N) availability is determined by microbial gross N mineralisation (GNM) and immobilisation, where net N mineralisation (NNM) represents their balance. Plants provide a substantial amount of their photosynthesized ...Article -
Reallocation of nitrogen and phosphorus from roots drives regrowth of grasses and sedges after defoliation under deficit irrigation and nitrogen enrichment
Published 20211. Reallocation of nutrients from roots to shoots is essential for plant regrowth in grasslands, particularly in nutrient-poor conditions. However, the response of root nutrient reallocation to changes in nitrogen (N) and ...Article -
A novel 13C pulse-labelling method to quantify the contribution of rhizodeposits to soil respiration in a grassland exposed to drought and nitrogen addition
Published 2021Rhizodeposition plays an important role in below-ground carbon (C) cycling. However, quantification of rhizodeposition in intact plant–soil systems has remained elusive due to methodological issues. We used a 13C-CO2 ...Article -
Carbon efficiency for nutrient acquisition (CENA) by plants: role of nutrient availability and microbial symbionts
Published 2022Background In a recent framework, Raven et al. (2018) considered carbon cost of acquiring phosphorus by mycorrhizal and non-mycorrhizal plants. Scope We broaden their conceptual framework by incorporating belowground ...Article -
Carbon allocation to the rhizosphere is affected by drought and nitrogen addition
Published 20211. Photosynthetic carbon (C) allocated below-ground can be shared with mycorrhizal fungi in exchange for nutrients, but also added into soil as rhizodeposits that potentially increases plant nutrient supply by supporting ...Article
