“…Second, the addition of the decomposer might have offset some negative effects caused by the initial straw and soil chemical composition and the unfavorable soil moisture and temperature conditions during the early stages of straw decomposition through the multilateral reaction among them, synergistically enhancing the buried straw decomposition and C and N release, which was similar to the finding in the maize straw incubation reported by Qin et al (2015). Finally, the released straw C and N were slowly converted into soil carbon and nitrogen that reduced the native SOC and SON lost via crop uptake, increasing soil carbon and nitrogen accumulation and storage (Akhtar et al 2018).…”

“…This showed that adding decomposer with FM tillage also was the most favorable technique for straw C and N degradation and release. This contributed to the synergistic effects of enhanced soil microbial activity and modified soil hydrothermal conditions (Zhao et al 2017;Akhtar et al 2018). Also, the results indicate that a fast release of straw C and N lasted for 210 days of incubation in the presence of the straw decomposer, but it was longer than that found by Wang (2015) and Ali Abro et al (2011), mainly because of the difference in the incubation period and the aerobic conditions.…”

“…Agricultural management measurements, such as tillage, straw mulching and incorporation, fertilization, and organic amendments, have played a great role in promoting soil fertility (Su et al 2006;Diacono and Montemurro 2010;Cong et al 2012;Laird and Chang 2013;Zhang et al 2013;Shang et al 2014;Vega-ávila et al 2018) and soil productivity (Unger 1978;Blanco-Canqui and Lal 2009;Pan et al 2009;Liu et al 2014;Akhtar et al 2018;Sheidai Karkaj et al 2019). Particularly, the application of full plastic film-mulched ridge-furrow rainwater harvesting technique (FM) has not only increased soil water content due to the reduced soil evaporation (Li et al 2016) but also greatly increased crop yield attribute to the increase in soil water content and temperature (Ye and Liu 2012;Gan et al 2013;El-Sadek and Salem 2015).…”

There is limited understanding of the effects of straw incorporation with decomposition agent (refer to decomposer) under full plastic film-mulched ridge-furrow tillage (FM) on straw decomposition rate and soil fertility. A direct field incubation test of straw with and without decomposer (T1 and T2) under FM using the litter bag method and a 3-year field experiment of five treatments including conventional planting (CP, as control), CP with straw incorporation (CP S), CP with straw incorporation plus decomposer (CP SD), FM with straw incorporation (FM S), and FM with straw incorporation plus decomposer (FM SD) were conducted in 2014-2016. The results showed that the initial straw N content, indigenous soil nitrogen content, and soil hydrothermal conditions were all remarkably affected by maize straw decomposition, and C and N release regardless of the decomposer. Applying the decomposer resulted in 80.3% decomposition of maize straw, leading to 81.3% of straw C and 83.3% of straw N release into the soil, which were 1.4, 1.1, and 1.06 times than that of CK, respectively. Meanwhile, the FM SD was significantly better in improving soil nutritional conditions, particularly for the tested parameters of soil organic carbon (SOC), soil total nitrogen (TN), available nitrogen (AN), available phosphorus (AP), and available potassium (AK). Importantly, FM SD drove a strong synergistic effect of decomposer and the modified soil hydrothermal conditions in comparison with CP, which led to the significant increase in SOC, TN, TP, AN, AP, and AK by 4.4-8.7%, 5.2-7.5%, 3.0-6.8%, 11.1-12.6%, 3.6-60.5%, and 6.2-54.6%, respectively. Therefore, FM SD is the best model for more efficient and sustainable soil fertility management in semiarid areas in China.

“…Agricultural sustainability is defined as the ability of a crop production system to continuously produce food without environmental degradation (Pan et al., 2021; Pang et al., 2020). The use of rice straw and different tillage practices are considered eco‐friendly strategies for sustainable agriculture crop production (Kashif et al., 2018). Sustainable crop production, especially rice farming under a dual cropping system in south China is thought to be achievable by effective conservation management practices.…”

Background The degradation in soil quality over the last four decades poses a major threat to the sustainability of the puddled transplanted rice (Oryza sativa L.) system in southern China. Conservation tillage practices (CTPs) such as no‐tillage and crop straw mulching (SM) are considered effective strategies for achieving sustainable crop production. Aims This study aimed to assess the efficacy of different CTPs on crop yield and soil properties in an ongoing long‐term field experiment (2008–2020), particularly changes in soil chemical properties and enzymatic activities and their relationship with rice grain yield. Methods Five treatments including conventional tillage (CT), CT and straw retention, CT and SM (CT‐SM), no‐tillage (NT), and NT and SM (NT‐SM) were applied at a field scale over a period of 12 years. In Years 11 (2019) and 12 (2020), soil samples were collected at two depths (0–10 cm and 10–20 cm) after rice harvesting. Soil chemical traits, enzymatic activities, and rice production were measured in response to different CTPs treatments, and differences between treatments were assessed. Results Soil pH, soil organic carbon, total nitrogen (N), available N, total phosphorus (P), and available P were significantly higher in CTP treatments, compared with CT. The activities of soil enzymes including invertase, acid phosphatase, urease, catalase, β‐glucosidase, and cellulase were significantly higher in CTP soils, compared with CT soils. A general trend of lower enzyme activity was observed at the deeper soil depth. The NT‐SM treatment fields consistently produced the highest grain yield and larges differences in edaphic properties relative to the CT fields; however, all CTP treatments lead to significant increases in grant yield and edaphic properties relative to CT. A correlation analysis demonstrated that the enhancement in soil enzymatic activities contributed to soil quality and grain yield of rice. Conclusions The results of this long‐term field study indicate that the use of CTPs in paddy soil can benefit farmers in southern China by improving soil functionality and sustainability and the grain yield of rice.

“…This increase in fruit yield was especially observed in the application of DSM and PM of 120 cm soil depth. It could be due to the various effects of mulch on plant growth periods such as protection of surface soil structure and rainwater, improving soil physical and chemical properties, and increasing water storage capacity (Kashif et al, 2018).…”

E GGPLANT (Solanum melongena L.) is one of the drought-tolerant vegetable crops, however, recently climate change has had a devastating impact on crop cultivation in many parts of Iran. The present research aimed to investigate the application of date straw mulches (DSM) and plastic mulches (PM) on yield and morphological and physiological characters of the plant under different crop water requirements. A split-split plot experiment using an RCB design with three replications in Rodan, Hormozgan, Iran at 2017. The three levels of crop water requirement (CWR), i.e. 40, 70, and 100%, the two levels of DSM (i.e. control and DSM), and the three levels of PM (i.e. 0, 100, and 120 cm in soil depths), were allocated in the main, sub and sub-sub plots, respectively. The results of the analysis of variance revealed that the triple-interaction effects of the DSM, PM, and CWR were statically significant for all traits (P < 0.05 or P < 0.01). However, none of the simple and interactions effects were not statically significant for leaf length and width. The results revealed that 40% of CWR reduced the yield by 49% compared with 100% CWR. Also, the application of the DSM and PM alleviated the deleterious effects of water deficit. Finally, the application of the mulches is recommended for eggplant in areas affected by water shortages.
