“…The POM consists of partially decomposed plant litter, and it acts as a substrate and center for soil microbial activity, a shortterm reservoir of nutrients, a food source for soil fauna, and loci for formation of water stable macroaggregates (Haynes 2005). The POM could be considered a larger contributor to total SOC as Mandal et al (2019) showed a high positive correlation between POM carbon and SOC. The MHA is a labile fraction of humic substances rich in N, S, and H, characterized by phenolic moieties derived from the lignin residues, involved in short-term nutrients cycling (Olk 2006).…”

Organic farming can overcome the environmental consequences of intensive conventional farming. The objective of the work was to investigate the changes in labile soil organic matter (SOM) fractions during the conversion from conventional to organic farming in two Italian sites, namely Foggia (FG) and Metaponto (MT), which differed mainly in initial soil organic carbon (SOC) content. Fields were cultivated with lentil and wheat in rotation and treated with either compost or nitrogen or phosphorus (N/P) fertilizers in three field replicates. The SOM was sequentially fractionated into light fraction (LF), particulate organic matter (POM), and mobile humic acid (MHA) fraction. Isolated fractions were quantified and analyzed for C and N contents. Although total SOC responded to the fertilization treatments, the LF and POM fractions were yet more responsive. The MHA represented on average of 15% of SOC at both sites; however, the LF represented only 5-6% of the total SOC but was the most responsive to changes in soil management. Compost application contributed significantly greater quantities of LF, POM, and MHA than did the N/P fertilizers application. The initial SOC content can play an important role in determining the impacts of introducing organic farming practices on SOM fractions. Although both sites had an initial low SOC content, the MT site, with a lower SOC content, showed a substantial fractional C increment as compared to the FG site.

“…It could be due to the higher biomass of plants at below and above ground, recalcitrance of leaf litter and plant root biomass of natural forest trees (Jha et al, 2012). Among the cultivated LUSs, the greater amount of SOC in the horticultural land-use might be due to higher addition of plant biomass into the soil in the form of leaf litter residue as well as less disturbance compared to other LUSs (Mandal et al, 2020). Loss of , 1996;Meena et al, 2012).…”

“…3). The regression analysis The agricultural LUS had reduced the SOC concentration by oxidation of labile fraction of organic matter due to intensive tillage practices and soil disturbances (Purakayastha et al, 2008;Mandal et al, 2020). A higher correlation among SOC and nitrogen and other soil nutrients suggested that the production and concentration of these nutrients were principally determined by the amount and quality of soil organic matter under different USs (Meena et al, 2018).…”

Aim: This investigation was carried out to appraise the effect of different prevailing land-use systems (LUSs) on nutrient status along with deterioration indices of soil under sub-humid Southern Plains of Rajasthan. Methodology: Six dominant land-use systems: barren, agricultural, agri-horticulture, horticultural, grass, and natural forest were selected in the sub-humid Southern Plains of Rajasthan. A total of 120 composite soil samples [6-LUSs, 4- soil depths (0-20, 20-40, 40-60, and 60-80 cm), and five replications] were collected for laboratory analysis. The two-way analysis of variance was used to test the effect of different LUSs and soil depths on available nutrients, essential properties with deterioration indices of soil. Results: The results of the study showed that soil organic carbon (SOC), DTPA extractable Zn, Mn, available nitrogen, and CEC are the most degraded soil fertility parameters under studied LUSs. Barren land-use has led to the highest decline in Zn (͌75%), SOC (71%), N (66%), Cu (62%) and Fe (57%), followed by Agricultural land-use that has led to a decline in SOC (53%), Zn (46%), N (43%) and Mn (38%). The use of soil deterioration indices revealed that soils deteriorated slightly under grassland and horticultural LUSs (-11.05 and -11.81 %). However, moderate deterioration was observed in the agri-horticulture land-use soil (-22.51 %) while severe (-28.11%) and extremely severe deterioration (-47.50%) occurred under agricultural and barren LUSs, respectively. Interpretation: The result of this study implies that consistent cultivation without appropriate land-use management practices in the cultivated LUS aggravates the deterioration of soil organic carbon and essential soil fertility parameters. These results suggested that restoration of barren and agricultural lands into horticultural, agri-horticulture, and grassland-uses consequently decreased soil disturbance which could be an effective strategy for improving or maintaining the soil quality and sustainability in the study area.

“…Overall the higher proportion of macroaggregates was observed for CS 1 . This may be attributed to higher amount of organic carbon (Table 1) which affected the activity of soil fauna and also soil aggregation [34]. Macro-aggregate formation is linearly correlated with SOC content [27].…”

Organic farming is gaining momentum because of awareness among consumers for quality food. The long term effects of organic cropping systems on soil quality yet not have been studies in details. Therefore the present study the long term effect of five cropping systems viz. Poplar (Populus deltoids) + turmeric (Curcuma longa), sugarcane (Saccharum officinarum Linn )+ bottle gourd (Lagenaria siceraria) - broccoli (Brassica oleracea), basmati rice (Oryza sativa) - wheat (Triticum aestivum), sugarcane fodder and maize (Zea mays) + summer moong (Vigna radiate) - wheat on soil physico-chemical properties was studied at Bhagat Puran Singh Natural Agriculture Farm and Research Centre, Amritsar, Punjab (31.5730 N, 75.0660 E). The depth wise soil samples from these cropping systems were collected after rabi (2018-19) and kharif (2019) seasons. Poplar + turmeric cropping system has significantly higher soil organic carbon(SOC), soil carbon stock(SOCS), soil aggregate associated carbon(AAC), water stable soil aggregates (WSA) and mean weight diameter(MWD) of soil than other cropping systems. Sugarcane fodder cropping system has significantly higher soil pH than other cropping systems while basmati rice - wheat cropping system has significantly lower electrical conductivity (EC) and higher soil bulk density (BD) compared to other cropping systems. In the top soil (0-7.5 and 7.5-15 cm depths) SOC, SOCS, AAS, EC, WSA and MWD were significantly higher than subsurface layers (15-22.5 cm and 22.5-30 cm depth) whereas soil pH and BD were significantly lower in surface soil than subsurface soil.
