Localized basal area affects soil respiration temperature sensitivity in a coastal deciduous forest [PDF]

Biogeosciences, 2020
Abstract. Soil respiration (Rs), the flow of CO2 from the soil surface to the atmosphere, is one of the largest carbon fluxes in the terrestrial biosphere. The spatial variability of Rs is both large and poorly understood, limiting our ability to robustly scale it in space. One factor in Rs spatial variability is the autotrophic contribution from plant

Carbon allocation and carbon isotope fluxes in the plant-soil-atmosphere continuum: a review [PDF]

, 2011
The terrestrial carbon (C) cycle has received increasing interest over the past few decades, however, there is still a lack of understanding of the fate of newly assimilated C allocated within plants and to the soil, stored within ecosystems and lost to ...

The biochar effect on soil respiration and nitrification

Plant, Soil and Environment, 2018
Soil microorganisms play a main role in the nutrient cycle and they also play an important role in soil health. This article studies the influence of three rates of biochar (0.5, 1 and 3%) in comparison with control (0 biochar) in two different soils ...

Earthworms accelerate rice straw decomposition and maintenance of soil organic carbon dynamics in rice agroecosystems [PDF]

PeerJ, 2020
Background To promote straw degradation, we inoculated returned farmland straw with earthworms (Pheretima guillelmi). Increasing the number of earthworms may generally alter soil organic carbon (SOC) dynamics and the biological activity of agricultural ...

Assessment of the Health of Soils Contaminated with Ag, Bi, Tl, and Te by the Intensity of Microbiological Activity

Life, 2023
Soil health is the basis of ecological and food security for humanity. Among the informative indicators of soil health are microbiological indicators based on the intensity of the carbon dioxide release from the soil.

Can combined compost and biochar application improve the quality of a highly weathered coastal savanna soil?

Heliyon, 2021
Soil fertility decline is a major constraint to crop production in sub-Saharan Africa. The positive effect of biochar and compost applications on soil fertility has been reported by many authors.

Soil quality, leaf litter quality, and microbial biomass interactively drive soil respiration in a microcosm experiment

Soil Organisms, 2021
Soil respiration plays a central role in global carbon dynamics, and small changes in the magnitude of soil respiration could have large impacts on atmospheric CO2 concentrations.

Basal soil respiration in land use and cover systems in a caatinga enclaves moist forest

Semina: Ciências Agrárias, 2022
Deforestation and the disorderly exploitation of natural resources for agricultural expansion occurred at an accelerated pace in the Brejo microregion of the state of Paraíba, Brazil, which resulted in abandonment and erosion of the soil in a large part of the region.
