“…Environmental influences on shifts in AMF communities. Tillage and cover crop residue management are particularly imperative for controlling plant-microbe interactions and crop performance 75,76 . In general, cover crop residues that have been incorporated into the soil surface by conventional tillage systems release allelopathic substances that can inhibit weed germination, establishment, and growth 77 .…”

Our understanding regarding the influence of intensive agricultural practices, including cover cropping and tillage, on communities of arbuscular mycorrhizal fungi (AMF) is lacking. This would prove to be an obstacle in the improvement of current maize (Zea mays L.) production. therefore, using amplicon sequencing, we aimed to clarify how AMF communities and their diversity in maize roots vary under different cover cropping systems and two types of tillage (rotary and no tillage). Two kinds of cover crops (hairy vetch and brown mustard) and fallow treatments were established with rotary or no tillage in rotation with maize crops. Tillage and no tillage yielded a set of relatively common AMF operational taxonomic units (OTUs) in the maize crops, representing 78.3% of the total OTUs. The percentage of maize crop OTUs that were specific to only tillage and no tillage were 9.6% and 12.0%, respectively. We found that tillage system significantly altered the AMF communities in maize roots. However, the AMF communities of maize crops among cover cropping treatments did not vary considerably. Our findings indicate that compared with cover cropping, tillage may shape AMF communities in maize more strongly. Growing cover crops and practicing conservation tillage are agricultural practices worldwide that have been recommended to promote soil fertility. In particular, Williams et al. 1 reported that conservation tillage, including reduced or no tillage, modifies water-holding capacity and structure of soil in conservative agricultural systems. In general, conservation tillage can improve soil aggregation, increase the amount of soil organic carbon in the surface layer, and reduce erosion 2,3. Moreover, conservation tillage enhances soil microbial diversity and the abundance of beneficial functional soil microorganisms 3,4. The soil microbial communities stimulated by conservation tillage can play important roles in soil aggregation, soil carbon sequestration, and soil nutrition; improve water use efficiencies; and influence crop yields 5,6. The practice of cover cropping potentially reduces soil and wind erosion 7 , enhances soil organic matter 8 , inhibits weed establishment 9 , and increases the abundance and activity of arbuscular mycorrhizal fungi (AMF) 10. Indeed, crops with AMF have a greater capacity to take up phosphorus (P), zinc (Zn), and water 10 than crops without AMF. This greater capacity generally results in robust crop growth under conditions of limited nutrient availability or drought. AMF also contribute to increasing plant resistance against pathogens and help make crops generally healthier 11-13. AMF also contribute to crop health indirectly because of their effects on soil processes in agricultural settings 14,15. In particular, they can contribute to soil health, soil aggregate formation, and soil stability by increasing the soil's nutrient cycling and organic matter content 16,17. However, certain agricultural practices have negative influences on AMF abundance and functions 18,19. For example, convent...

“…Crop residue retention is one of the three components [(a) minimum mechanical soil disturbance, (b) permanent soil cover, and (c) crop rotation] of conservation agriculture (CA) (Kumar, Panda, Srivastava, & Mishra, 2017; Ojeda et al, 2015; Ye et al, 2019). Crop residues reduce the ills of conventional agriculture (Das et al, 2020; Das, Ghosh, Lal, Saha, & Ngachan, 2017; Kassam et al, 2014) and improve the soil for adaptation to climate risks (Thierfelder et al, 2018).…”

Soybean–wheat cropping system is the most commonly used in the black soil of India which produces enormous amounts of nutrient‐rich residues. However, black soil has some production limitations, such as rapid drying, high bulk density, low nutrients, and poor microbial populations, making it vulnerable to degradation. Optimal retention of soybean and wheat residues in black soil under the zero‐tillage (no‐till) system can improve soil properties and help protect the land from degradation. Thus, the main objective of this study was to test the effect of different levels of soybean and wheat residue retention on the physical, chemical, and biological properties of black soil. Therefore, an experiment was conducted in the zero‐tillagesoybean–wheat system at the Indian Institute of Soil Science, Bhopal, India from 2014 to 2018. In this study, the effect of four levels of soybean and wheat residue retention (no residue, 30, 60, and 90%) on soil properties was evaluated. Results revealed that soil organic carbon (C) significantly increased from 0.67 to 1.0% in 5 years through 90% residue retention. Retaining 90% (7.0 t) of soybean residue added 2.9 t C, 197.3 kg nitrogen (N), 32.4 kg phosphorus (P), and 89.7 kg potassium (K) in 5 years, while 6.2 t C, 85.7 kg N, 15.3 kg P, and 232.2 kg K were added through 90% (13.8 t) wheat residue during the same period. Different pools of soil C (oxidizable, labile, and particulate organic matter (OM)‐carbon), soil OM, soil moisture, soil porosity, available nutrients, and bacterial, fungal, and actinomycetes count was significantly enhanced due to retention of 90% residue over 60 and 30%. It was observed that retention of 90% soybean and wheat residues (7.0 and 13.8 t ha−1, respectively) significantly improved the physical, chemical, and biological properties of black soil in 5 years, therefore protected the soil from degradation.

“…In addition, many studies have shown that tillage practices and stubble management play an important role in the soil nitrogen pool. No tillage with straw mulching increased the TN content of the topsoil and affected soil nitrogen cycle (Ye et al 2019 ). In present study, straw mulching treatment resulted in a 6.60% and 4.01% increase in TN and AN content, respectively.…”

“…The present study found the contents of NH 4 + -N and NO 3 − -N in straw mulching groups decreased significantly during wheat harvest compared with the no straw mulching groups. Therefore, no tillage with straw mulching significantly reduced the content of mineral nitrogen in the surface soil and slowed down the deep accumulation of nitrate nitrogen in the soil to a certain extent (Ye et al 2019 ; Dong et al 2019 ). The present study also confirmed that straw mulching and fertilization increased the content of AK.…”

Microbe-mediated ammonia oxidation is a key process in soil nitrogen cycle. However, the effect of maize straw mulching on the ammonia oxidizers in the alkaline purple soil remains largely unknown. A three-year positioning experiment was designed as follows: straw mulching measures as the main-plot treatment and three kinds of nitrogen application as the sub-plot treatment. We found the contents of soil organic carbon (SOC), total nitrogen (TN), available potassium (AK), available nitrogen (AN), available phosphorus (AP), and NH4+-N were increased after straw mulching and nitrogen application in alkaline purple soil, so did the amoA genes abundance of ammonia-oxidizing archaeal (AOA) and bacterial (AOB). Terminal restriction fragment length polymorphism (T-RFLP) analysis revealed that Thaumarchaeote (448-bp T-RF) was dominated the AOA communities, whereas Nitrosospira sp (111-bp T-RF) dominated the AOB communities. The community compositions of both AOA and AOB were altered by straw mulching and nitrogen application in alkaline purple soil, however, the AOB communities was more responsive than AOA communities to the straw mulching and nitrogen application. Further analysis indicated that SOC and AP were the main factors affecting the abundance and community compositions of AOA and AOB in alkaline purple soil. The present study reported that straw mulching and nitrogen strategies differently shape the soil ammonia oxidizers community structure and abundance, which should be considered when evaluating agricultural management strategies regarding their sustainability and soil quality.
