“…This observation is consistent with Singh and Agrawal (2011) and Mi et al (2016) that the application of organic fertilizers leads to increasing the values of organic carbon compared with NPK fertilizer. In addition, adding municipal sewage sludge compost results in increasing of TOC values (Pena et al 2015).…”

“…Our results suggest that T2 and T5 have a relatively positive effect on soil ρb. In contrast, other studies have reported higher ρb under NT at 0-5 cm depth compared to CT in cropping systems other than RRS [35,38,39]. Soil pH is an important soil quality factor affected by farmers practice and its modifications in the present study ( Figure 1B).…”

“…Continuous imposition of FP (T1) over three years did not affect the ρb significantly, probably due to the incorporation of 30% straw and FYM. Positive effect of crop residues on soil ρb at the surface 10 cm depth has been reported previously [33][34][35]. Puddling (wet tillage) in rice is known to increase soil ρb immediately below the plow layer due to the destruction of soil aggregates, filling of macropores with finer soil particles, which ultimately reduces the porosity and direct physical compaction caused by the tillage implements [36,37].…”

“…The positive effect of conservation tillage along with organic manure and residue retention/incorporation in increasing the TOC in paddy soils of India have also been reported [7,43,45,49]. Further, the integrated uses of organics with inorganic fertilizers also have been reported to enhance productivity and SOC concentration over that with the sole application of fertilizer or manure [35,50].…”

“…The variation in TOC stock and sequestration were attributed largely to addition of carbon through recycling of organic sources (FYM/GLM), reduction in tillage intensity (RT/NT), crop residue cover (30% residue), root biomass, nutrient-use pattern, soil texture and prevailing ecosystem [35,51]. Therefore, the data suggested a modification of traditional FP with conservation tillage (NT/RT), INM, incorporation/retention of crop residue in cropping systems, use of micro nutrient and application of CDM for enhancing SOC concentration and stock in the region.…”

Over centuries and even today, traditional farming practices are well performed without any ecological degradation. However, management practice such as conservative tillage combined with nutrient and residue could increase the crop production as well as soil fertility. A three-year replicated study was conducted to assess the effects of agronomic modification of traditional farming practices on productivity and sustainability of rice (wet season)-rice (dry season) system (RRS). The replacement of farmers practice (T 2 ) with conservation effective tillage (no-till (NT)) and integrated nutrient management (INM) practice along with 30% residue retention (T 5 ) enhanced the straw, root and biomass yield of both wet season rice (WR), dry season rice (DR) and system as a whole over T 2 . Treatment T 5 recorded significantly lower soil bulk density ( b ) and higher pH than the T 2 after three years of the experiment. Further, treatment T 5 increased total soil organic carbon (2.8%), total soil organic carbon stock (2.8%), carbon sequestration rate (336.5 kg ha −1 year −1 ), cumulative carbon stock (142.9%) and carbon retention efficiency (141.0%) over T 2 of 0-20 cm depth after three year. The soil microbial biomass carbon concentration was significantly the highest under T 5 . Similarly, the dehydrogenase activity was the maximum under T 5 . Adoption of conservation tillage and nutrient management practice involving NT and INM along with residue retention can enhance the system productivity, and C and N sequestration in paddy soils is thereby contributing to the sustainability of the RRS.

Organic input is a widely recognized amendment for soil organic carbon (SOC) sequestration and soil quality improvement. A short-term (2-yr) field experiment was conducted to evaluate the effects of green manure (GM) planting, wheat (Triticum aestivum L.) straw return and farmyard manure application, and their interactions on SOC sequestration in a rain-fed winter wheat system in Northwest China. Ten combinations of two cultivation practices, conventional wheat monoculture (G0) and green manure-winter wheat rotation (G), and five fertilization methods during the wheat season: (a) no basal fertilization (B0), (b) basal chemical fertilization (B), (c) basal chemical fertilization plus wheat straw return (B + S), (d) basal chemical fertilization plus manure application (B + M) and (e) basal chemical fertilization plus wheat straw return and manure application (B + S+ M) were tested. Compared with theircontrols, M, S, and G increased the SOC stock in the 0-to-10-cm soil layer by an average of 20.7, 6.8, and 6.3%, respectively, and increased in the 10-to-20-cm soil layer by an average of 15.8, 4.7, and 6.6%, respectively. Manure exhibited a 55.9% carbon sequestration efficiency (CSE) in the 0-to-20-cm soil layer, followed by GM and wheat straw which exhibited CSEs of 27.7 and 19.3%, respectively. Nevertheless, combinations of G, M, and S, increased the SOC stock in cumulative manners without significant interactions. Positive relationships (P < .05) existed between the SOC sequestration and cumulative C input in both G0 and G. Therefore, G, S, and M, and their combinations were all effective for SOC sequestration in this cropping system.The G + M+ S was optimal for promoting SOC sequestration over the short term.
