Abstract:
... A comprehensive evaluation of the impact of forest harvest on soil N₂O flux at the global scale is currently unavailable. In this study, by using a global meta-analysis of 64 observations from 29 peer-reviewed publications over the last 30 years, we elucidated how forest harvest impacted soil N₂O flux and related soil properties. Intensive forest harvest significantly increased soil N₂O flux with ...

Abstract:
... The internal correlation of plant, litter and soil stoichiometric characteristics and their responses to the environment are helpful for revealing nutrient cycling mechanisms. However, few studies have assessed the nutrient relationship between plant, litter and soil and nutrient stock along elevational gradients, which limit the understanding of nutrient relationships in the ecosystem. To gain in ...

Abstract:
... Expansion of oil palm has caused widespread declines in biodiversity and changes in ecosystem functioning across the tropics. A major driver of these changes is loss of habitat heterogeneity as forests are converted into oil palm plantations. Therefore, one strategy to help support biodiversity and functioning in oil palm is to increase habitat heterogeneity, for instance, by retaining forested bu ...

Abstract:
... Thinning and replanting are effective forest management measures to improve the stand structure and species composition of artificial forests. However, the effects of thinning and replanting on soil N₂O and CH₄ fluxes and their associations with changes in soil environment factors have been poorly understood in plantation forests. A 36-month field experiment was conducted to elucidate the effects ...

Abstract:
... The soil family was developed in the 1960s as the fourth level of taxa within the hierarchical structure of the Canadian System of Soil Classification. The original aim of the soil family category was to provide a framework for checking and establishing limits for soil series while providing a link between the series and the subgroup level. Its intended use was to define and group numerous soil se ...

Abstract:
... This paper reviews the literature on crop residue burning - a widespread practice in many regions in South Asia. Specifically, we examine evidence from studies highlighting the scale of the practice in South Asia, the environmental implications, the drivers of the practice and the remedies to the problem. The studies provide evidence that the Indo-Gangetic Plain (IGP) is a hot-spot for atmospheric ...

Abstract:
... Since soil temperature (ST) is one of the most critical determinants affecting the soil’s physical and chemical properties, the studies on soil temperature estimation increase with the widespread use of deep learning and machine learning algorithms. This study estimates soil temperature at four depths for Giresun and Bayburt stations in Turkey employing the Bayesian Tuned Gaussian Process Regressi ...

Abstract:
... We developed a mechanistic, stage-structured model simulating the phenology of Popillia japonica. The model simulates the influence of soil temperature on the larval diapause termination and on the development rate function of post-overwintering larvae and pupae. Model parameters are estimated based on literature evidence for pupae development and on a parameterisation process that allows estimat ...

Abstract:
... Unraveling the biogeographic pattern of soil fungal decomposers along temperature gradients—in smooth linearity or an abrupt jump—can help us connect the global carbon cycle to global warming. Through a standardized global field survey, we identify the existence of temperature thresholds that control the global distribution of soil fungal decomposers, leading to abrupt reductions in their proporti ...
... The saffron dormancy period begins after drying above-ground parts, including actual and apparent phases. The differentiating reproductive organs during apparent dormancy need to be induced under optimal temperature conditions, while saffron farms are free of vegetation after the drying phase. Covering the soil surface during the summer season may be advantageous to counter such a major constraint ...

Abstract:
... Optimizing yields while reducing soil CO₂ emissions in cropping systems has become the focus of agricultural study. To explore effective ways to achieve the balance, short-term field experiments (2018–2020) were conducted in North China Plain. Three replications of three-factor combinations of two tillage systems (i.e., no-tillage and conventional tillage), two straw management (i.e., no straw and ...

Abstract:
... Two years field experiment was done to investigate the impact of aromatic crops based cropping systems and crop residue returning on soil CO₂ efflux and its relationship with soil temperature and moisture. Eight diversified cropping systems were compared to fallow soil as control, total nine treatments: T₁-(B-W-C) (basil-wheat-cowpea), T₂-(B-W-M) (basil-wheat-menthol mint), T₃-(B-P-C) (basil-potat ...
... Soils have been widely acknowledged as important natural sources of nitric oxide (NO) and meanwhile sinks of nitric dioxide (NO₂). High nitrogen deposition across South China could potentially result in large NO emissions from subtropical forests soils there. In this study, the dynamic chamber method was applied to monitor NO and NO₂ fluxes at two subtropical forest sites in South China, namely “Q ...

Abstract:
... The rubber tree (Hevea brasiliensis) belongs to the evergreen broadleaved species in its native ranges, but it has a concentrated leaf senescence period after it was introduced to the Asian tropics. The mechanism behind the leaf senescence is still unclear. Models for predicting leaf senescence dates of this introduced tree have been rarely explored. This study proposed a series of models to ident ...

Abstract:
... Wetlands are emitters of greenhouse gases. However, many of the wetlands remain understudied (like temperate, boreal, and high-altitude wetlands), which constrains the global budgets. Himalayan foothill is one such data-deficient area. The present study reported (for the first time) the greenhouse gas fluxes (CO₂, CH₄, N₂O, and H₂O vapor) from the soils of the Nakraunda wetland of Uttarakhand in I ...
... Subtropical wetlands sequester vast carbon (C) and their C cycles are sensitive to global changes, such as climate warming and increased nitrogen (N) deposition. However, little is known about the effects of warming and increased N deposition on ecosystem respiration (Re) and methane (CH₄) emission from subtropical wetland ecosystems. In this study, a manipulated warming and N addition experiment ...

Abstract:
... Increasing winter temperature in lower Gangetic Plain of India has put a threat to the cultivation of summer rice along with decreasing fresh water availability. Increasing ambient temperature also increase the soil temperature in the root zone of the crop. Thus, the effect of soil temperature over an optimum value may be detrimental for the root growth which turns into reduction of grain yield. K ...

Abstract:
... Soil respiration is an important ecosystem process in drylands and is closely related to soil temperature but often occurs out of phase with soil temperature. As ecosystem engineers in dryland ecosystems, biological soil crusts (biocrusts) greatly affect soil carbon cycle processes, such as soil respiration. However, the diel hysteresis pattern between soil respiration and soil temperature at bioc ...
... Agricultural activities contribute to greenhouse gas emissions, but agroecosystems can also mitigate emissions by adding recalcitrant carbon sources such as biochar to soil. Our goal was to understand if greenhouse gas emissions decrease in soil amended with manure and biochar (MN) or with manure, nitrogen fertilizer, and biochar (MNB) than soil amended with manure and N fertilizer (MN) over the l ...
