“…Higher turn-over of root biomass under integrated nutrient management (FYM + NPK) also might have attributed to higher increase in this pool as compared to other treatments. Our results are in agreement with the values reported by Rudrappa et al, (2006), Purakayastha et al, (2008), Moharana et al, (2012).…”

“…This might be due to higher organic carbon content observed in surface as com-pared to sub-surface soil. The results are corroborated with the findings of Walia et al, (2010), Moharana et al, (2012), Datt et al, (2013 The NPK dose was applied through urea, DAP and MOP. FYM and rice straw applied were 36.6 and 46% total carbon.…”

“…Increase in TOC in optimal and balanced application of NPK is because of greater input of root biomass due to better crop growth. It was supported by the data published by Moharana et al, (2012) who noted. Similar effects of manure and inorganic fertilizer applications on soil organic C has also been reported by Rudrappa et al, (2006).…”

“…The highest value of MBC due to integrated use of FYM and NPK fertilizer might be due to higher turn-over of root biomass produced under FYM + NPK treatment. Similar increases in integrated nutrient management with manure + fertilizer have been reported by others (Moharana et al, 2012;Nayak et al, 2012). In a long-term field experiments in Denmark, Powlson et al, (1987) showed that straw manure could increase MBC up to 45%.…”

“…In this study, the combination of organic and inorganic fertilization enhanced the accumulation of SOC which is consistent with many other studies (Hao et al, 2008;Banger et al, 2009). Significant increase in SOC in FYM and straw treated plots over control was also reported by Zhang et al, (2010) and Moharana et al, (2012).…”

Long‐term effects of straw mulching coupled with N application on soil organic carbon sequestration and soil aggregation in a winter wheat monoculture system

Straw mulching can be affected by N fertilization rate with regard to improving soil organic carbon (SOC) lability, which modifies the net accumulation of SOC and soil aggregation. We conducted a 14-yr field experiment to determine how straw mulching coupled with N application rates affects crop yield, SOC sequestration as a net gain of SOC, and soil aggregation in a winter wheat (Triticum aestivum L.) monoculture system. Six combinations of two cultivation practices, conventional cultivation (CC) and straw mulching (SM), and three N application rates (0, 120, and 240 kg N ha -1 ) were compared. Results revealed that SM did not affect wheat yield throughout the 14 yr of cultivation, but increased the SOC stock, SOC lability, and the carbon management index (CMI) in surface soil (0-20 cm). Instead, N application, N120 and N240, increased the wheat production almost equally, and followed a trend for increasing SOC stock: N240 > N120 > N0; however, a different trend for increasing SOC lability and soil CMI (N120 > N240 > N0). Soil macro-aggregation was increased by SM but decreased with increasing N application. Principal component analysis (PCA) indicated that organic C input was the key to improving SOC sequestration, SOC lability, and soil macro-aggregation rather than N input, especially high N input (N240) reduced SOC lability and soil aggregation in soil. Consequently, medium N application (N120) may be expected to couple with straw directreturning for improving soil productivity and quality in this agro-system.
