“…And G7 led to the highest soil total N of 0-20 cm after wheat harvest (Table 6). All these results were consistent with a previous study (Xie et al, 2016). This may be resulted from that legumes could promote soil physical and biological properties (e.g.…”

The application of catch crops as a green manure can enhance soil fertility owing to improving soil nutrients. We conducted one year field experiment to evaluate the effect of catch crops [Rapeseed (Brassica napus L.) under different sowing rates and Soy bean (Glycine max L.)] with biological organic fertilizer 1,500 kg/ha on wheat yield and soil nutrients. The green manures were sown on 3 th July 2015 during summer fallow. At the beginning, there were five treatments as follows: R1 (Rapeseed and sowing rate was 7.5 kg/ha); R2 (Rapeseed and sowing rate was 15 kg/ha); R3 (Rapeseed and sowing rate was 22.5 kg/ha); S (Soy bean and sowing rate was 105 kg/ha); C (Control was bare field). Every green manure treatment was split into two treatments on 27 th September 2015. One treatment we turned the above ground biomass of green manure into the soil. And another treatment we harvested the above ground biomass of green manure. The above ground biomass turned into soil treatments were G1, G3, G5 and G7. The above ground biomass harvested treatments were G2, G4, G6 and G8. The treatment C was still the bare field. Soil samples were taken twice to measure soil moisture and nutrients at two stages. One stage was in autumn before winter wheat sowing and another stage was in next year summer after wheat harvest. The significantly highest 1,000-grain weight and grain yield belonged to the treatment C, which were 10.69%-36.87% and 16.86%-72.5% higher than that of the green manures treatments. After wheat harvest, the 0-20 cm soil available N and total N of G7 were 51.40%-20.45% and 95.12%-125.35% significantly better than that of other treatments. The significantly highest soil total P of 0-20 cm belonged to G3 after wheat harvest, which was 25%-45.83% better than other treatments. Before wheat sowing, the treatment C kept the significantly lowest soil available K of five layers. The 0-20 cm and 20-40 cm soil organic matter of the treatment S was 40.28%-71.12% and 53.92%-122.67% significantly higher than other treatments before wheat sowing. Therefore, growing rapeseed and soy bean during summer fallow in this region significantly reduced 1,000-grain weight and grain yield of subsequent winter wheat. But the incorporation of green manures improved the soil nutrients to some extent Abstract: The application of catch crops as a green manure can enhance soil fertility owing to improving soil nutrients.

“…Soil N and P content increased in the mudflat saltsoil amended with sewage sludge due to higher levels of these nutrients in the sewage sludge. Moreover, green manuring, such as Sesbania as a legume, may supply N through the N fixation process, thereby increasing N for soil fertility supply [55,56]. The increase in CEC of mudflat soil is probably due to increasing soil OM content [57,58].…”

Sewage sludge and green manure have become widely used organic amendments to croplands in many regions of the world. However, the amending effect of the combination of sewage sludge with green manuring in reclaimed coastal mudflat salt-soil has been unclear yet. This paper was one of earlier studies to investigate and evaluate the effects of sewage sludge amendment combined with green manuring on selected soil physicochemical properties of the mudflat soil in a rain-fed agroecosystem. The mudflat salt-soil was amended by one-time input of sewage sludge at the rates of 0, 30, 75, 150, and 300 t ha −1 . After green manuring for three consecutive seasons, maize (Zea mays L.) was planted in 2013 and 2014. The results showed that SSA combined with green manuring decreased bulk density, pH, salinity, and exchangeable sodium percentage of the topsoil (0-20 cm soil layer) and increased aggregate stability, cation exchange capacity, and N and P concentration of the topsoil. As a result, the maize yield increased with the increase of SSA rates. Sewage sludge combined with green manuring can be applied in coastal mudflat salt-soil amendment, which provides an innovative way to create arable land resources and safe disposal of sewage sludge.

“…In fact, using leguminous winter crop (e.g. CMV) residue as GM has been considered a beneficial practice to reduce the requirement for synthesized FN, improve soil N-supplying capacity and support sustainable rice productivity in the double-rice cropping system in southern China [30]. Hence, the CMV as winter crop in paddy fields has the potential to reduce the rice production costs as well as the environmental costs in rice-based cropping system.…”

Monocropped rice system is an important intensive cropping system for food security in China. Green manure (GM) as an alternative to fertilizer N (FN) is useful for improving soil quality. However, few studies have examined the effect of Chinese milk vetch (CMV) as GM on nitrous oxide (N2O) emission from monocropped rice field in south China. Therefore, a pot-culture experiment with four treatments (control, no FN and CMV; CMV as GM alone, M; fertilizer N alone, FN; integrating fertilizer N with CMV, NM) was performed to investigate the effect of incorporating CMV as GM on N2O emission using a closed chamber-gas chromatography (GC) technique during the rice growing periods. Under the same N rate, incorporating CMV as GM (the treatments of M and NM) mitigated N2O emission during the growing periods of rice plant, reduced the NO3- content and activities of nitrate and nitrite reductase as well as the population of nitrifying bacteria in top soil at maturity stage of rice plant versus FN pots. The global warming potential (GWP) and greenhouse gas intensity (GHGI) of N2O from monocropped rice field was ranked as M
