“…The historical mean annual rainfall is 630 mm, and mean monthly temperature is 23.4 • C (Figure 1). The texture of the soil (0-20 cm) at the experimental site is silt clay loam, and is classified as Lou soil (anthrosol) [29]. The properties of the soil at the 0-20 cm depth at the start of the experiment in October of 2016 were as follows: bulk density, 1.40 g•cm −3 ; saturated soil water content, 43.5%; and field capacity, 24.1%.…”

Straw retention and wheat-soybean rotation play critical role in maintaining soil quality. However, the correlation between bacterial diversity and community structure, and soil nutrients is unknown, and a systematic understanding of their responses to straw retention is lacking. In the field experiment, the straw retention treatments included no straw (NS), half straw (HS), and total straw (TS) retention during long-term wheat-soybean rotation. The mean contents of soil total nitrogen (TN), nitrate-N (NO3−-N), and microbial biomass nitrogen (MBN) increased by 15.06%, 21.10%, and 38.23%, respectively, with straw retention relative to NS, while that of ammonium-N (NH4+-N) reduced by 3.68%. The concentration of carbon components increased as straw retention increased. The levels of soil dissolved organic carbon (DOC), microbial biomass carbon (MBC), and soil organic carbon (SOC) increased by 4.34%, 7.63%, and 9.34%, respectively, with straw retention relative to NS. Soil bacterial alpha diversity was reduced with straw retention. Soil pH and nutrient content were identified as the main factors affecting the soil microbial diversity and structure at the phylum level. Accordingly, straw retention and soybean-wheat rotation enable sustainable agriculture in the dryland of northern China.

“…Soil samples from three repetitions at the same level were mixed to form a composite sample. Soil samples were air-dried in a room, and then passed through a 0.25 mm mesh, similar to the method described by Kong and Wang [28,30]. The gravimetric soil water content was determined as described by Wang in which soil samples were dried at 105 • C for 48 h [30].…”

Developing environmentally friendly and sustainable nitrogen (N) fertilizer management strategies is crucial in mitigating carbon dioxide (CO2) emission from soil. How N fertilizer management practices influence soil CO2 emission rates under different crop rotations remains unclear. The aim of this study was to assess the impact on soil CO2 emission and soil physicochemical properties of three N fertilizer treatments including traditional rate (TF), optimized rate (0.8TF), and no fertilizer (NF) under three different crop rotation treatments: wheat-fallow (WF), wheat-soybean (WS), and wheat-maize (WM) over two years in a field experiment in northwest China. The rates were 5.51, 5.60, and 5.97 μmol·m−2·s−1 of mean soil CO2 emission under the TF, 0.8TF, and NF treatments, respectively. Mean soil CO2 emission rates were 21.33 and 26.99% higher under the WM rotation compared with the WF and WS rotations, respectively. The WS rotation showed higher soil nutrient content and lower soil CO2 emissions, and reduced fertilizer application. Importantly, soil organic carbon (SOC) concentration in the topsoil can be maximized by including either a summer legume or a summer maize crop in winter wheat rotations, and by applying N fertilizer at the optimal rate. This may be particularly beneficial in the dryland cropping systems of northern China.

“…The reduction in soil fertility needs replenishing with the help of supplying organic matter from external sources for future sustainability (Muhammad et al, 2018;Akhtar et al, 2019a;Bome et al, 2022). Adding soil organic matter (SOM) is confirmed as an important indicator for improving crop productivity and soil sustainability by altering nutrient dynamics and soil physio-chemical and biological properties (Akhtar et al, 2018;Kong et al, 2019;Wang et al, 2020). Improving soil organic matter and ultimate soil fertility can result from adopting various soil and crop management techniques, including adding organic manures like compost, farmyard manure, poultry manure, and legume residues (Khan et al, 2015;Muhammad et al, 2018).…”

Adding organic matter to soil proved an efficient strategy for restoring soil fertility and improving crop dry matter – an indicator of yield potential. In this regard, evaluating the sources of organic matter (OM) (control, poultry manure [PM], farmyard manure [FYM], compost, and mungbean residues [MR]) to provide 120 kg N ha-1 and effective microbes (EM) (0, 100, 200, and 300 L ton-1 of OM) as 2% solution proceeded in field conditions during 2017–2019. The sowing of wheat seeds (cv. Pirsabak 2015) at 120 kg ha-1 took place in the field using RCB design with four replications. Results showed that PM/FYM had delayed the phenology and improved the biomass-related parameters, dry matter (DM) accumulation, and crop growth rate (CGR) more than compost and MR. However, the results were more pronounced when applied with 300 L EM ton-1 of OM from the PM. The maximum DM (55%) accumulation in plant parts occurred beyond 100 days after sowing (DAS). A marked increase in DM and CGR beyond 60 DAS and a reduction in CGR beyond 120 DAS appeared irrespective of treatments. In the case of EM, the 300 L ton-1 revealed superior in terms of growth, DM accumulation, CGR, and delayed phenology. Structural equation modeling suggested that DM production gained a direct effect from crop phenology (46.1%) and crop stand (30.4%) but no indirect effect from crop growth (24.8%). In conclusion, the 300 L EM ton-1 of OM applied to PM or FYM had improved the crop stand, development, and DM production in wheat.
