Soil Organic Carbon, Microbial Biomass, and Mineralizable Carbon and Nitrogen in Sorghum

Soil Science Society of America Journal, 1995
Abstract Quantifying changes in soil microbial biomass and mineralizable C and N is important in understanding the dynamics of the active soil C and N pools. Our objectives were to quantify long‐term and seasonal changes in soil organic C (SOC), soil microbial biomass C (SMBC) and N (SMBN), and mineralizable C and

Influence of Salt Content on Soil Microbial Biomass Carbon

2016
Soil salinization has become a global issue. Saline and alkaline arable land was taken as research object in this paper and four salt gradients were set (S1: 0.1%; S2: 0.5%; S3: 0.9%; and S4: 1.3%). Through the addition of different substrates (CK: no addition of substrate; N: addition of nitrogen source; C: addition of glucose, C+N: addition of ...

Structure Evaluation and Microbial Biomass Determining of Biological Activated Carbon

Advanced Materials Research, 2012
To investigate the microorganisms growth process and biostability of biological activated carbon by manual preparation, the microorganisms growth process were observed by the photos of optics and electronic microscope, and the microbial biomass was determined by phospholipids (Lipid-P) analysis.

Global patterns of vertical distribution of soil microbial biomass carbon

2020
<p>Small changes in soil organic carbon (SOC) may have great influences on the climate-carbon cycling feedback. However, there are large uncertainties in predicting the dynamics of SOC in soil profile at the global scale, especially the role of soil microbial biomass in regulating the vertical distribution of SOC.

A comparison of methods for estimating soil microbial biomass carbon

Agriculture, Ecosystems & Environment, 1991
Abstract Soil microbial biomass is an important ecological parameter because it acts as a source-sink in nutrient cycling processes and regulates many organic matter transformations. Appropriate methodologies must be developed to measure the microbial pools in natural and man-managed (agroecosystems) systems. Our objective was to compare and contrast

Improving Sweep Efficiency in Fractured Carbonate Reservoirs by Microbial Biomass

SPE EOR Conference at Oil and Gas West Asia, 2012
Abstract Selective plugging by microbial biomass is one of the proposed mechanisms for improving reservoir sweep efficiency in fractured reservoirs. In this study, the potential of Bacillus licheniformis strains isolated from oil contaminated soil from the Sultanate of Oman was tested for their ability to grow in induced fractures in ...

Soil Microbial Biomass and Mineralizable Carbon of Water‐Stable Aggregates

Soil Science Society of America Journal, 1997
Abstract Biophysical alterations of agricultural soils following adoption of zero tillage (ZT) deserve investigation in order to better understand the processes of soil organic C (SOC) sequestration and turnover.

Turnover of “new” and “old” carbon in soil microbial biomass

Microbiology, 2013
The contributions of “new” carbon coming from plants with the C4-type of photosynthesis (maize) and “old” carbon from soil organic matter (SOM) formed under C3 vegetation as carbon sources for microorganisms was determined. Soil samples were taken from the plots of field experiments on Chernozem and Phaeozem.

Microbial Biomass Carbon and Nitrogen Under Different Maize Cropping Systems

2014
Soil microbial biomass carbon (C) and nitrogen (N) under different maize cropping systems were evaluated at Kampe Irrigation Project farmlands in Southern Guinea savanna region of Nigeria. In 40-ha irrigated plots that have been cultivated for minimum of 3 years with sole maize, maize/okra, and maize/cowpea intercrops, maize/okra relay cropping and a 5
