“…Clearly, such incorporation and mulching practices can exert effects on the subsequent crop, for instance wheat (Rahman et al, 2005) and Chinese milk vetch (Astragalus sinicus L.), by virtue of modulations of soil microbial activity and diversity (Tang et al, 2020). Moreover, the treatments require mechanization and often water and additional fertilizer are added to enhance decomposition processes (Kalkhajeh et al, 2021). Furthermore, in flooded soils, RS decomposition may substantially increase methane emissions (El-Sobky, 2017).…”

“…The C: N ratio was low, which favors the OM mineralization, however, the treatment with stubble incorporation always significantly (P≤0.05) greater than the treatment with burning in all the depths studied, since is incorporated organic matter with high ratio C:N. In this regard 25 , determined that a C:N = 18 ratio is optimal for the decomposition of stubble, and in this research they varied in the range of 9.73 (T2.5) to 12.53 (T1.10).…”

Stubble burning in Chile is a common practice used for the farmers but it causes nutrient losses, erosion and environmental pollution. An alternative to change this situation is the incorporation of crop residue to improve the soil quality. The objective of this research was to compare the effects of the incorporation of oat stubble and stubble burning on the chemical and physical properties in an Humic Haploxerands soil with crop rotation oat-wheat. A completely randomized experimental design was used by two treatments of incorporation and stubble burning with soil sampling at depths of 0-5, 5-10 and 10-20cm, with three replicates. The results showed that stubble incorporation represents an sustainable management alternative for the ash volcanic soils, that improve the soil pH, organic matter , potassium exchangeable , aggregates stability and soil porosity.

“…Returning straw to the field can avoid the environmental pollution caused by straw burning and accumulation [17]. In addition, returning straw can also fertilize the soil, reduce the runoff of surface water, increase soil water storage, and prevent soil compaction caused by a single application of chemical fertilizers [18].…”

“…Studies have shown that the effect of returning straw on rice yield is different, mainly due to differences in physical and chemical properties of the soil, and the rate of straw decomposition is determined by geothermal conditions of the soil [18]. Water management [19], fertilizer management [18], farming methods [11], experiment year [20], and straw returns also affect the impact of returning straw on rice yields [21].…”

The rice-ratoon system has long been considered an important economic, time-saving, and labor-saving planting method. Optimal tillage and straw management are beneficial to increasing the growth and yield of recycled rice. However, there is little research on the physical and chemical properties of soil under tillage and straw management, and its effects on the yield and fertilizer utilization of recycled rice. A field experiment was conducted to study the effects of four types of tillage and straw management on rice yield and soil properties in central China during 2020–2021. The types of management were no-till with residues retained (NT+S); plow tillage with residue retention (PT+S); no-till with residues removed (NT-S); and plow tillage with residue removed (PT-S). Compared with PT, yield decreased by 38.8% in NT, while straw returning effectively increased the yield of regenerated rice. NT+S increased the yield of main season rice by 37.0% and ratoon rice by 45.3%. Compared with non-returning straw, straw returning increased soil total porosity, soil organic carbon, and activity of β-glucosidase and urease, among which TP and SOC were increased by 8.8% and 27.8%, respectively. The results showed that returning straw to the field could significantly reduce the yield loss caused by no-tillage and improve the soil structure. No-tillage combined with returning straw to the field of regenerative rice is a green, light, and simplified cultivation mode worthy of further exploration.
