“…Our result findings can be explained by the enhanced soil biological activity of the additive decomposer (Zhao et al 2016;Siczek et al 2018) and the optimal soil moisture and temperature condition under FM S tillage (Potthoff et al 2008;Gan et al 2013;Liu et al 2018). Moreover, our results indicated that the fast decomposition period of the buried maize straw lasted for 120 days, with a much lower residual mass rate under T1 than that under T2, which was much longer than the finding in an anaerobic field incubation test of buried wheat straw reported by Wang (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.

“…was (37.88 and 21.21 %), while the increase in DHA-ase activity was (103.57 and 60.71 %) over that obtained under uninoculated plants irrigated by the same saline well. The result substantiates the findings of (Siczek et al, 2017;Cordero et al, 2020 andAbdel Latef et al, 2021). They concluded that under salt stress the total microbial count, nitrogen fixer count and dehydrogenase activity in the canola and pea rhizosphere was enhanced in response to inoculation with growth promoting rhizobacteria.…”

Salinity, a major environmental stress that inhibits agricultural productivity, has a negative impact on plant growth and development. The goal of this study was to use salt-tolerant bacteria to improve the plant's ability to resist salt-stress and to achieve high canola productivity in saline soil conditions. The rhizobacteria strains, Acinetobacter radioresistens (NBRC 102413) and Enterobacter cloacae (NBRC 102413) were evaluated for their ability to produce organic acids and phytohormones (IAA). A field experiment was conducted in the Agricultural Experimental Station in the Desert Research Center, Ras-Sudr, South Sinai Governorate, Egypt, during the winter season of 2018 / 2019. The researchers focused at how the inoculation with salt-tolerant bacteria and irrigation with three saline underground's water of (8.94, 11.12, and 12.1 dS m -1 ) affected some growth and yield parameters, as well as the nutrients content and intracellular organic osmolytes produced by canola plants grown in saline-calcareous soil. A. radioresistens and En. cloacae, were shown to be able to survive in a saline-nutrient broth medium containing up to 12 % NaCl. The highest values of plant fresh weight, dry weight, seeds yield and oil yield, nutrients content and osmo-protectant molecules (glycinebetaine and choline), as well as rhizosphere microbial counts and dehydrogenase activity, were recorded in treatment of the irrigation with low saline-underground water (8.94 dS m -1 ), while proline increased by using medium salineunderground water (11.12 dS m -1 ).

“…Pods of faba bean are rich in phenolic compounds [60], which are important chemicals engaged in diverse processes between plants and microbes: legume-rhizobia and arbuscular mycorrhizal symbioses and plant defense against pathogens [61]. As shown in an earlier study, flavonoids positively effect soil rhizosphere activity [62].…”

Forecrop Effects on Abundance and Diversity of Soil Microorganisms during the Growth of the Subsequent Crop

Plant residues introduced into the soil influence the soil’s physical, chemical, and consequently, biological parameters, which have an influence on plant health and yields. This study was undertaken to evaluate the effects of the cultivation of widespread plant species, faba bean (Vicia faba L., F) and wheat (Triticum aestivum L., W) (as forecrops) grown under conventionally tilled fields, on the diversity of microorganisms and the enzymatic activities of soil during the growth of the subsequent wheat. Bulk soil samples (0–20 cm) were taken three times from two months after residue incorporation into the soil to the maturity of the subsequent wheat crop in order to assess the fungal and bacterial communities (Next Generation Sequencing (NGS), terminal restriction fragments lengths polymorphism (t-RFLP)), ammonia oxidizing archaea (t-RFLP, denaturing gradient gel glectrophoresis (DGGE)), and the enzymatic activity of soil. Differences in the genetic structure of ammonia-oxidizing archaea (AOA) were observed for each treatment and sampling term, indicating that plant and weather conditions are the driving force for microorganism selection and adaptation. We observed that the fungal community was more influenced by the forecrop type used than the bacterial community. The activities of the enzymes changed in response to the forecrop and sampling period. A higher number of microorganisms that are associated with plant benefits with respect to nutrients and growth, as well as higher amounts of N in the residues, was noted in faba bean than in wheat soil. This could indicate better growth conditions after faba bean and, consequently, better yield quality and quantity. This may also indicate some protective role of the soil after faba bean against pathogens, which may be connected with lower fungicide requirements. The obtained results lead to a deeper understanding of the microorganism reactions to faba bean and wheat residues during wheat cultivation. In addition, they may be helpful in improving our understanding of subsequent crop yield responses to forecrops.
