Relationships between labile soil organic carbon fractions under different soil management systems [PDF]

open access: yesScientia Agricola, 2016
ABSTRACT The study of labile carbon fractions (LCF) provides an understanding of the behavior of soil organic matter (SOM) under different soil management systems and cover crops. The aim of this study was to assess the effect of different soil management systems with respect to tillage, cover crop and phosphate fertilization on the amount of the LCF ...

Effect of Six Different Feedstocks on Biochar’s Properties and Expected Stability

open access: yesAgronomy, 2022
Biochar (BC) is often proposed as a tool for climate change mitigation, due to the expected long lifetime in the environment. However, BC’s stability can vary depending on feedstock type and the presence of labile carbon fractions.

Sorption and fractionation of dissolved organic matter and associated phosphorus in agricultural soil [PDF]

open access: yes, 2007
Molibility of dissolved organic matter (DOM) strongly affects the export of nitrogen (N) and phosphorus (P) from oils to surface waters. To study the sorption an mobility of dissolved organic C and P (DOC, DOP) in soil, the pH-dependent sorption of DOM ...

Sources of nitrogen for winter wheat in organic cropping systems [PDF]

open access: yes, 2013
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure.

Stable carbon and radiocarbon isotope compositions of particle size fractions to determine origins of sedimentary organic matter in an estuary [PDF]

open access: yes, 2002
Stable and radioactive carbon isotopic compositions of particle size fractions of a surface sediment from the Ems-Dollard estuary vary considerably with particle size. The organic material in the fine fractions (

Soil Strength and Structural Stability Are Mediated by Soil Organic Matter Composition in Agricultural Expansion Areas of the Brazilian Cerrado Biome

open access: yesAgronomy, 2022
A growing demand for resources has led to the expansion of agricultural areas worldwide. However, land conversion associated with poor soil management might lead to soil physical degradation.

Labile and stabilised fractions of soil organic carbon in some intensively cultivated alluvial soils.

open access: yesJournal of environmental biology, 2014
The present investigation was undertaken in view of the limited information on the relative proportion of labile and stabilized fractions of soil organic carbon (SOC) in intensively cultivated lands, particularly under tropics. The specific objectives were i) to study the comparative recovery of SOC by different methods of labile carbon estimation ...

Sensitivity of labile carbon fractions to tillage and organic matter management and their potential as comprehensive soil quality indicators across pedoclimatic conditions in Europe [PDF]

open access: yes, 2019
Soil quality is defined as the capacity of the soil to perform multiple functions, and can be assessed by measuring soil chemical, physical and biological parameters.

Fractions of particulate organic matter in soils depending upon farmyard manure and mineral fertilization [PDF]

open access: yes, 2002
In a long-term fertilization trial particulate organic matter (POM) was investigated after 20 years of farmyard manure vs. mineral fertilization at different levels with the method of Meijboom et al. (1995).

Pools of organic carbon in soils under a long-term rice–rice system with different organic amendments in hot, sub-humid India

open access: yesCarbon Management, 2020
Study of soil organic carbon pools is helpful to understand the mechanism of carbon sequestration in soil. It was hypothesized that different management practices and sources of organics applied to soil will change the carbon allocation into various ...
