[Soil basal respiration and enzyme activities in the root-layer soil of tea bushes in a red soil].

Ying yong sheng tai xue bao = The journal of applied ecology, 2003
Soil basal respiration potential, metabolic quotient (qCO2), and activities of urease, invertase and acid phosphomonoesterase were investigated in the root-layer of 10-, 40-, and 90-yr-old tea bushes grown on the same type of red soil. The soil daily basal respiration potential ranged from 36.23 to 58.52 mg.kg-1.d-1, and the potentials in the root ...

Estimating the soil respiration under different land uses using artificial neural network and linear regression models

CATENA, 2019
Soil respiration is a biological process in microbes that convert organic carbon to atmospheric CO2. This process is considered to be one of the largest global carbon fluxes and is affected by different physicochemical and biological properties of soil ...

Partitioning of total soil respiration into root, rhizosphere and basal-soil CO2 fluxes in contrasting rice production systems

Soil Research, 2020
Soil respiration contributes significantly to ecosystem respiration and is vital in the context of climate change research. In a season-long experiment we studied total soil respiration (TSR) and its partitioning into root respiration, rhizospheric respiration (RhR) and basal-soil respiration in four contrasting rice production systems: irrigated ...

Effects of water amendment on basal and substrate-induced respiration rates of mineral soils

Biology and Fertility of Soils, 1989
We studied the effects of amending soils with different volumes of water or glucose solution on respiration rates measured as CO2 evolution. Basal respiration was not significantly affected by the volume of water amendment, but substrate-induced respiration in static soil solutions was significantly reduced by increasing water contents.

Soil CO2 Emission, Microbial Biomass, and Basal Respiration of Chernozems under Different Land Uses

Eurasian Soil Science, 2019
The relationships between the soil CO2 emission and microbial properties have been studied in Haplic Chernozem of steppe, forest (oak), bare fallow of the reserve area and in Urbic Technosols of Kursk city. The CO2 emission was monthly measured (May–October) from the soil surface (EMsurf) and two subsoil layers at the depths of 10 and 20 cm (EM10, EM20)

Basal and specific microbial respiration in semiarid agricultural soils: Organic amendment and irrigation management effects

Geomicrobiology Journal, 1993
Evolution of microbial activity in semiarid agricultural soils was studied measuring the basal (CO2 evolved) and specific microbial respiration (qCO2). The effects of straw residue management (buried or removed), irrigation (dry or irrigation farming), and chemical composition of the soils (calcareous, gypsiferous, or saline) were analyzed.

Microbial biomass-C and basal respiration of fine earth and highly altered rock fragments of two forest soils

Soil Biology and Biochemistry, 2001
Abstract Highly altered rock fragments (dimension limits between 2 and 10 mm) from two sandstone-derived soils, Cavalla and Buca, of the Vallombrosa Forest, Italy, are porous and manifest chemical properties similar to those of fine earth.

[Effects of Miscanthus floridulus on microbial biomass and basal respiration in heavy metals polluted soils].

Ying yong sheng tai xue bao = The journal of applied ecology, 2009
Vegetation coverage is an important parameter in terrestrial ecological process, meteorological, and climatic models. By eliminating the errors from the precision of image classification and the noises of remote sensing images, and by using the actual data from fieldwork, this paper determined the maximum and minimum values of normalized difference ...
