A compartmentation approach to deconstruct ecosystem carbon fluxes of a Moso bamboo forest in subtropical China

open access: yesForest Ecosystems
Moso bamboo (Phyllostachys edulis) forests are a vital resource in subtropical China, known for their high carbon (C) sequestration capacity. However, the dynamic processes of C fluxes within each component (canopy, culm, and soil) and their individual ...

One Hundred Years of the German Soil Science Society (DBG) 1926–2026: Origins, Facts, and Background of an Eventful History

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT On its 100th anniversary in 2026, the German Soil Science Society (DBG) is looking back not only on an eventful history with traditions and impressive achievements but also with painful interruptions and ruptures. One curious fact is that the DBG was initially founded as the national section of the International Soil Science Society (ISSS ...

Nitrogen and potassium fertilization regulates source–sink relations, biomass allocation, and nutrient dynamics for industrial biomass production in cassava (

open access: yesIndustrial Crops and Products
Cassava fertilization primarily targets the enhancement of fresh storage-root yield, while fresh stem-and-leaf yield, source-sink allocation, and nutrient balances are often overlooked.

The German Soil Systematics and the Rationale Behind Its Revision

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Root-to-shoot signaling positively mediates source-sink relation in late growth stages in diploid and tetraploid wheat

open access: yesBMC Plant Biology
Non-hydraulic root source signaling (nHRS) is a unique positive response to soil drying in the regulation of plant growth and development. However, it is unclear how the nHRS mediates the tradeoff between source and sink at the late growth stages and its

Towards stochastic simulation of crop yield: a case study of fruit set in sweet pepper [PDF]

open access: yes, 2010
Crop growth simulation models are widely used in research and education, and their use in commercial practice is increasing. Usually these models are deterministic: one set of input values always gives the same output of the model.

Food Security Versus Environmental Health: The Nitrogen Dilemma

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Land‐Use Thresholds and Spatial Regulation Oriented Toward Ecosystem Service Supply–Demand Balance: A Case Study of Jiangxi Province

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Imbalances between ecosystem service (ES) supply and demand constrain ecological governance and sustainable development. While spatial patterns of these imbalances have been widely studied, less attention has been paid to the land‐use thresholds and regulatory mechanisms needed to maintain ES balance. Using Jiangxi Province as a case study, we

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...
