Integrated Microbiome and Metabolomic Analysis Reveal Responses of Rhizosphere Bacterial Communities and Root exudate Composition to Drought and Genotype in Rice (Oryza sativa L.)
Background As climate change events become more frequent, drought is an increasing threat to agricultural production and food security. Crop rhizosphere microbiome and root exudates are critical regulators for drought ...
Continuous application of conservation tillage affects in situ N2O emissions and nitrogen cycling gene abundances following nitrogen fertilization
Fertilized agricultural soils can be a major source of soil nitrous oxide (N2O) emissions to the atmosphere. Conservative soil management may have the ability to reduce N2O emissions through affecting a number of ...
Global pattern of soil priming effect intensity and its environmental drivers
The microbial priming effect – the decomposition of soil organic carbon (SOC) induced by plant inputs – has long been considered an important driver of SOC dynamics, yet we have limited understanding about the direction, ...
Quantifying regional effects of plastic mulch on soil nitrogen pools, cycles, and fluxes in rain‐fed agroecosystems of the Loess Plateau
Farmland surface soil mulching with plastic film is extensively used to enhance agricultural productivity in the Loess Plateau (LP). However, the effect of mulching on the key processes that dominate soil nitrogen dynamics ...
A synthesis of soil organic carbon mineralization in response to biochar amendment
Biochar amendment can alter native soil organic carbon (SOC) mineralization via the priming effect (PE);
however, its direction, intensity, and controls over a broad geographic scale are not clear, undermining the ...
Nutrient limitation of soil organic carbon stocks under straw return
Straw return has been widely used to increase SOC storage globally, but such C accrual is frequently constrained by other nutrients which are needed to maintain soil ecological stoichiometry balance. However, the impact ...
Brassinosteroids alleviates wheat floret degeneration under low nitrogen stress by promoting the distribution of sucrose from stems to spikes
The trade-off between yield and environmental effects caused by nitrogen fertilizer application is an important issue in wheat production. A reduction in fertile florets is one of the main reasons for decreased yield under ...
