“…Soils are known as one of the largest active carbon pools after the hydrosphere and the lithosphere. The role of soils as either a source or a sink for greenhouse gases, in general, and that of CO 2 , in particular, has been a focus of recent studies (Majumder et al 2008;Bhattacharyya et al 2009). …”

“…Whereas the largest terrestrial pool of carbon is located in the soils (Bhattacharyya et al 2009), there are many factors that influence on carbon retention and release in soil and also carbon exchange between soil and atmosphere (Majumder et al 2008). Storage of organic carbon (OC) in agricultural systems is a balance between carbon additions from non-harvested portions of crops (Wang et al 2011), organic sources (Thelen et al 2010) and carbon losses, primarily through organic matter decomposition and release of respired CO 2 to the atmosphere (Bird et al 2002).…”

Introduction Organic carbon (OC) fractions play important roles in soil and many ecosystem processes. This study focuses on changing of OC in density and soluble fractions in a soil amended by nanozeolite and plant residues that incubated in lab condition for 90 days.Results The results showed that amounts of OC in light fraction (LF) and heavy fraction (HF) increased with the increasing percentage of nanozeolite and plant residues in the soil. The highest amounts of LF (7.54 g LF. kg -1 Soil ) and HF (11.10 g kg -1 Soil ) were found when 30 % nanozeolite and 5 % wheat and alfalfa straws were added to the soil. Accordingly, wheat and alfalfa straws were effective on increasing the LF and HF, respectively. However, they decreased with declining the OC from the 1st day of experiment until the 90th day of experiment. Soluble OC in hot (2.22 g kg -1Soil ) and cool (1.54 g kg -1Soil ) water fractions increased by addition of 30 % nanozeolite and 5 % plant residues particularly alfalfa straw in comparison with control. Although these soluble fractions increased after initial 30 days of incubation, they decreased in the continuation of the experiment. Conclusion In fact, OC contents in density and soluble fractions increased by addition of 30 % nanozeolite and 5 % plant residues into the soil; however, they decreased in initial 30 days of incubation with declining the OC. The findings of this research revealed the application of nanozeolite and plant residues improved carbon pools in density and soluble fractions and carbon sequestration increased by increasing OC contents in soil.

“…On oxidation, this pool of SOC adds to the loading of CO 2 to the atmosphere to accentuate global warming. At the same time, this pool of SOC fuels the soil food web and therefore greatly influences nutrient cycling for maintaining soil quality and its productivity (Chan et al 2001;Majumder et al 2008a, b). On the other hand, stabilized fraction is composed of organic materials that are highly resistant to microbial decomposition and hardly serves as a good indicator for assessing soil quality and productivity (Weil et al 2003;Sherrod et al 2005;Majumder et al 2008a, b).…”

Soil organic matter not only affects sustainability of agricultural ecosystems, but also extremely important in maintaining overall quality of environment as soil contains a significant part of global carbon stock. Hence, we attempted to assess the influence of different tillage and nutrient management practices on various stabilized and active soil organic carbon pools, and their contribution to the extractable nitrogen phosphorus and sulfur. Our study confined to the assessment of impact of agricultural management practices on the soil organic carbon pools and extractable nutrients under three important cropping systems, viz. soybean-wheat, maize-wheat, and rice-wheat. Results indicated that there was marginal improvement in Walkley and Black content in soil under integrated and organic nutrient management treatments in soybean-wheat, maize-wheat, and rice-wheat after completion of four cropping cycles. Improvement in stabilized pools of soil organic carbon (SOC) was not proportional to the applied amount of organic manures. While, labile pools of SOC were increased with the increase in amount of added manures. Apparently, green manure (Sesbania) was more effective in enhancing the lability of SOC as compared to farmyard manure and crop residues. The KMnO(4)-oxidizable SOC proved to be more sensitive and consistent as an index of labile pool of SOC compared to microbial biomass carbon. Under different cropping sequences, labile fractions of soil organic carbon exerted consistent positive effect on the extractable nitrogen, phosphorus, and sulfur in soil.

“…Great attention is currently paid to the lability of soil organic matter characterised by labile fractions of soil carbon while these fractions are considered as a significant indicator of soil quality (Ghani et al 2003, Haynes 2005, Maia et al 2007, Majumder et al 2007, 2008. The labile fraction is characterised in a different way.…”

“…It may be hot-or cold-water soluble carbon compounds, mineralised organic matters, substances extractable with K 2 SO 4 solution, soluble saccharides, proteins and hemicelluloses. The lability of organic matters is derived from basal respiration carbon, content of aminosugar nitrogen, microbial biomass carbon, content of particulate organic matter carbon, from fractions of gradual oxidation with K 2 Cr 2 O 7 in 6M, 9M and 12M of H 2 SO 4 or with 6M, 9M and 12M H 2 SO 4 and from fractions of labile carbon oxidisable with 15.6, 33 and 333 mmol/l KMnO 4 , from kinetics of their microbial oxidation as the firstorder reaction (Vance et al 1987, Blair et al 1995, Chan et al 2001, Rovira and Vallejo 2002, Ni et al 2004, Zhang et al 2004, Gelsomino et al 2006, Jiang and Xu 2006, Kolář et al 2006, Marriot and Wander 2006, Majumder et al 2007, 2008, Passos et al 2007, Soon et al 2007, Vieira et al 2007). …”

We performed 28-day mesophilic fermentation of a mixture of pig slurry and primary (raw) sludge from the sedimentation stage of a wastewater treatment plant at a 1:1 ratio. The components and the original and fermented mixture of slurry and sludge were subjected to acid hydrolysis. Dry matter of the solid phase of both components and both mixtures was incubated with sandy-loamy Cambisol at a weight ratio 3:1 at 25°C for 20 weeks; in 14-day intervals lipids, crude protein, hemicelluloses, cellulose, lignin, total nitrogen and hot-water-insoluble solids were determined. Changes in ion-exchange and buffering capacity of the test materials were recorded. Labile organic matters were determined after 20 weeks of incubation. Liquid fractions of both components and their mixtures were analysed before and after anaerobic fermentation. It was concluded that beneficial effects of wastes as fertilisers from anaerobic digestion could be attributed to their liquid fraction. After anaerobic digestion the solid fraction of these wastes has relatively increased ion exchange capacity as well as buffering capacity but it is very stable, hardly degradable organic matter, and therefore it cannot play the role of organic matter in soil. This is the reason why it should not be considered as an organic fertiliser.
