“…Previous studies [52,53] also stated that higher amounts of straw incorporation affected the emergence rate of the rice crop and the growth quality at the seedling stage. These findings are also supported by prior research [23,28,54], which concluded that higher rice grain yields were produced by the balanced input of residue with RT methods compared to the control or other nutrient management practices.…”

“…This might be due to the incorporation of the aboveground crop residue into the soil layer. Prior studies also demonstrated that residue incorporation into soil effectively improved the soil structure and helped reduce soil dry bulk density compared to the treatments without straw [21][22][23]. In terms of the soil profile layer (0-30 cm) and residue incorporation, we showed that soil dry bulk density significantly decreased the most in the topsoil layer, from depths of 0 to 10 cm, in all treatments.…”

“…Changes mainly occurred when smaller quantities of crop residues were incorporated into the soil [41]. Similarly, Yadav et al [23] and Mi et al [24] concluded that SOM significantly improved with the incorporation of straw into the soil profile at depths of 0-40 cm under RWR system. Soil total nitrogen (TN) is one of the main factors for determining soil fertility.…”

Soil management practices are used to enhance soil organic carbon, fertility, and crop productivity around the world. However, accurate information about the appropriate amount of straw incorporation is not available, because it is generally believed that at least 30% of the soil surface should be covered by straw, which is not implemented in all field environments. Therefore, a two-year (2016-2017) field experiment was conducted to investigate the impact of different percentages of straw incorporation and tillage methods, i.e., reduced tillage (RT) and conventional tillage (CT), on crop yield, soil organic carbon (SOC), total nitrogen (TN), and soil carbon storage (SCS) in rice-wheat cropping systems, under eight treatments. The experimental results showed that the greatest reduction in soil dry bulk density (ρ b ) was found under CT with 100% straw coverage (9.79%), whereas the least reduction occurred under CT with no straw (1.31%). The mean TN concentration, soil organic matter (SOM), and soil carbon storage (SCS) were significantly higher by 0.98 g/kg, 17.07%, and 14.20%, respectively, under reduced tillage with 60% straw incorporation (RTsi 60 ) compared with all other treatments. Our findings demonstrate that the incorporated wheat residues resulted in the highest rice production (7.95-8.63 t/ha) under RTsi 60 . We recommend the adoption of reduced tillage with 60% straw incorporation to increase rice yield, improve soil structure, and enhance TN, SOM, and SCS in paddy soil under rice-wheat rotation fields for agricultural sustainability.

“…Janke [46] in their research work suggested that the multi-megawatt project can be developed using sugarcane residue. The C/N ratio in the legume (10)(11)(12)(13)(14)(15), sugarcane straw (~ 83) and bagasse (~ 116) indicate lower proportions of the nitrogen in comparison to carbon, hence a lower quantity of nitrogen in sugarcane can be optimized by mixing with legumes to stabilize the anaerobic digestion [47,48]. It also improved biogas production and digested quality for the use as biofertilizer.…”

The crisis of fossil fuel and their negative impact on the environment has caused concern among the scientific communities leading them to look around for renewable sources of energy. This review has emphasized the efficient utilization of organic municipal solid waste as well as agriculture waste in an anaerobic digester for the production of biogas as a sustainable renewable energy. Recent advances in biogas production along with previous research work have been discussed to offer a comprehensive synopsis of the accumulated knowledge. This review also elucidates about the design of an anaerobic digester, the prospect of anaerobic digestion and opportunity in new advances in technology. Biogas is one of the most accepted sustainable renewable energy. The characterization, elimination of contaminants, pretreatment, anaerobic digestion in optimum condition and utilization of energy crops enhanced the efficiency of an anaerobic digester. Pretreatment of segregated organic solid waste increased its putrescibility and further biogas production. The optimized parameters in this review were pH, temperature, loading rate, C/N ratio and solid/liquid ratio of the feedstock. The flow rate of the feedstock was optimized according to the available volume of the digester, residence time and the characteristics of the feedstock. The design of an anaerobic digester should be preferably cylindrical in shape, with a diameter ranging from 6 to 40 m, the depth ranging from 7.5 to 15 m and the conical floor having a slope around 15%. A comprehensive reform in technical, economic, and social policies is essential to accomplish a sustainable energy system considering biogas as a future renewable energy. The flowsheet of the biogas and methanol production has been given in Fig. 1.

“…[5,6]. One main mechanism by which they do this is by changing the quantity and quality of plant biomass supplied to the soils, affecting the rate of organic matter decomposition and the activity of soil microorganism and redistributing soil carbon and nutrients within soil profiles [7][8][9]. Another main mechanism is the impact of soil erosion, which preferentially removes the surficial and most carbon and nutrient rich material, thus accelerating the decline of the soil organic carbon and soil nutrient pool [10,11].…”

In response to land degradation and the decline of farmers’ income, some low quality croplands were converted to forage or grassland in Northeast China. However, it is unclear how such land use conversions influence soil nutrients. The primary objective of this study was to investigate the influences of short term conversion of cropland to alfalfa forage, monoculture Leymus chinensis grassland, monoculture Leymus chinensis grassland for hay, and successional regrowth grassland on the labile carbon and available nutrients of saline sodic soils in northeastern China. Soil labile oxidizable carbon and three soil available nutrients (available nitrogen, available phosphorus, and available potassium) were determined at the 0–50 cm depth in the five land uses. Results showed that the treatments of alfalfa forage, monoculture grassland, monoculture grassland for hay, and successional regrowth grassland increased the soil labile oxidizable carbon contents (by 32%, 28%, 15%, and 32%, respectively) and decreased the available nitrogen contents (by 15%, 19%, 34%, and 27%, respectively) in the 0–50 cm depth compared with cropland, while the differences in the contents of available phosphorus and available potassium were less pronounced. No significant differences in stratification ratios of soil labile carbon and available nutrients, the geometric means of soil labile carbon and available nutrients, and the sum scores of soil labile carbon and available nutrients were observed among the five land use treatments except the stratification ratio of 0–10/20–30 cm for available phosphorus and the values of the sum scores of soil labile carbon and available nutrients in the 0–10 cm depth. These findings suggest that short term conversions of cropland to revegetation have limited influences on the soil labile carbon and available nutrients of sodic soils in northeastern China.
