Nitrogen addition and defoliation alter belowground carbon allocation with consequences for plant nitrogen uptake and soil organic carbon decomposition.
Published 2022Grassland plants allocate photosynthetically fixed carbon (C) belowground to root biomass and rhizodeposition, but also to support arbuscular mycorrhizal fungi (AMF). These C allocation pathways could increase nutrient ...Open AccessArticle -
Decoupled cycling of carbon, nitrogen, and phosphorus in a grassland soil along a hillslope mediated by clay and soil moisture
Published 2022Grasslands extend across a variety of topographies including non-flat hilly areas with varied soil texture and moisture that can mediate soil biogeochemical cycling of carbon (C), nitrogen (N) and phosphorus (P). In ...Open AccessArticle -
Ameliorating soil acidity with calcium carbonate and calcium hydroxide: effects on carbon, nitrogen, and phosphorus dynamics
Published 2023Calcium carbonate (CaCO3) is frequently used to ameliorate soil acidity in agricultural soils. An alternative is calcium hydroxide (Ca(OH)2), which is more soluble than CaCO3. However, the associated change in soil ...Open AccessArticle -
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 ...Open AccessArticle -
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 ...Open AccessArticle
