“…However, after SR, microorganisms must absorb more organic carbon from the soil during stover decomposition, which leads to a decrease in organic carbon in the soil and eventually reduces the efficiency of microbial decomposition. Therefore, applying an appropriate amount of N to the soil will regulate C/N and benefit plant growth (Zhou et al 2019(Zhou et al , 2020. Stover buried in the ground consumes some N when it is decomposed by microorganisms, which compete with the crop for N. This competition affects both the efficiency of stover decomposition and crop growth (Zhong et al 2020).…”

Cultivation techniques have an important influence on grain yield of maize. This experiment investigated the effect of stover return (SR) and different nitrogen (N) application rate on soil organic carbon (SOC) composition, soil nutrient and maize yield.• Different nitrogen application rate 100 (N100), 150 (N150), 200 (N200), 250 (N250) or 300 (N300) kg ha À1 applied to the maize field with stover return and without stover return traditional planting (TP) method.• Nitrogen application rate and stover return affected the SOC, labile organic carbon (LOC), microbial biomass (MBC), NO 3 À -N, NH 4 + -N and maize yield. Soil N, soil carbon content and maize yield of SR were all higher than TP. The SOC content of SR and TP were 9.67 and 9.19 g kg À1 , respectively. Nitrogen application was significantly and positively correlated with soil MBC, LOC, SOC, NO 3 À -N, NH 4 + -N and yield. The maximum values of SOC composition, soil nutrients and maize yield were reached at SR with 250 kg ha À1 .• Stover return with application of N 250 kg ha À1 significantly increased the growth attribute and maize yield in subtropical region compared with traditional planting.

“…In furrow irrigated rice and in alternate wetting and drying rice irrigation systems, with the greater likelihood of suboxic and oxic soil conditions having longer durations, encourage a more robust nitrification-denitrification sequence [12] [23] [32]. The microbial-mediated denitrification process is represented by the half-cell reaction: In the USA mid-South, delayed flood nitrogen fertilization programs typically have a rice variety dependent nitrogen application rate at the 5 th leaf stage, followed by an internode elongation application to support grain-fill photosynthesis.…”

The nitrogen cycle is the basis for understanding nitrogen dynamics in soil fertility and ecosystem health. Nitrification and denitrification are key nitrogen cycle components that influence nitrogen uptake in food crops, thus critical to food security. Rice (Oryza sativa) is comparatively unique in that the nitrification-denitrification sequence is a perceived loss of available nitrogen for plant uptake and the production of nitrous oxide (N 2 O) has severe implications in climate change. This review focuses on recent research involving nitrification and denitrification, with an emphasis on rice. The review also focuses on the emerging irrigation strategies associated with furrow irrigation and alternating wetting-drying irrigation. With growing global interest in reducing irrigation water application, new research paradigms are emerging to perfect these reduced water applications systems to guarantee food security and farm profitability.

“…This poses a negative impact on the content of available nitrogen to plants in the soil and also slows the decomposition process [5]. On the other side, animal manure has a high nitrogen concentration and narrow C/N ratio and hence usually leads to high C and N mineralization [6]. Das et al [7] found that, comparatively, mixtures of straw and animal dung are more suitable for composting and improving soil properties other than the individual application of each component.…”

Straw and animal manure are major organic waste materials from agricultural ecosystems. Different kinds of animal manure combined with straw (AM-S) may have varying effects on the decomposition, nutrient release, and structural changes of maize straw. Using the Humic Cambisols soil as the experimental area, the straw decomposition characteristics under the co-application of animal manure were studied following the nylon net bag landfill method. The experiment involved four treatments: maize straw only (S), maize straw plus ox manure (SO), maize straw plus chicken manure (SC), and maize straw plus pig manure (SP). The treatments with AM-S accelerated the decomposition of straw and increased the release rate of nutrients and organic components (cellulose, hemicellulose, and lignin). During the 240 days of the study, straw decomposition showed a trend of increasing rapidly in the first stages and then increasing slowly in the latter stages in all the treatments. At 240 d, the straw decomposition rates and carbon release rates of the AM-S treatments were 65.25–71.87% and 64.04–69.35%, respectively. At the end of the experiment, the order for the final release rates of nitrogen (N), phosphorus (P), and potassium (K) was K (93.25–96.56%) > P (42.25–55.08%) > N (40.01–52.23%). Moreover, scanning electron microscopy showed that SP treatment had the highest degree of structural changes of the maize straw compared with the other treatments. The purpose of this study was to screen the effective animal manure that can promote straw decomposition and provide a reference for the rational use of straw and animal manure management. In conclusion, the study suggested that the co-application of animal manure and straw should be adopted in agricultural systems, especially SP treatment, as it was more conducive to promoting the decomposition of maize straw and the release of nutrients.
