TL;DR: In this article, the combined effects of different N and P fertilizer application rates with or without manure on maize (Zea mays L.) yield, N uptake, root growth, apparent N surplus, Olsen-P concentration, and mineral N (Nmin) accumulation in a fluvo-aquic calcareous soil from a long-term (28-year) experiment were investigated.

TL;DR: In this paper, the impact of alternate wetting and drying (AWD) irrigation on N2O emissions in rice cropping systems under Mediterranean climate was investigated. And the authors concluded that the duration of flooding, transition to aerobic conditions, water level above the soil surface, and the relative timing between fertilization and flooding were the main drivers affecting greenhouse gas mitigation potential under AWD and should be carefully planned through site-specific management options.

TL;DR: In this paper, the authors compared a fallow-winter wheat (Triticum aestivum L.) rotation to several cover crop-Winter wheat rotations under rainfed and irrigated conditions in the semi-arid US High Plains.

TL;DR: In this article, a controlled greenhouse experiment was set up to evaluate plant reactions as well as changes of P availability in a sandy soil with high P status and a Rheinsand soil with low P status.

TL;DR: The results showed that application of strain W19-enriched BIO significantly promoted the growth and fruit yield of banana while suppressing the banana Fusarium wilt disease.

TL;DR: A modified plate assay is developed based on improved visualization of halo zone formation around the colonies on agar plates, through inclusion of an acid-base indicator dye, bromothymol blue (BTB), to modify the previously reported Aleksandrov medium.

TL;DR: Wang et al. as mentioned in this paper investigated the effects of both incubation temperature and soil moisture on SOM decomposition and its temperature sensitivity at different elevations, and found that the importance of soil moisture to decomposition of soil organic matter and its Q10 value was emphasized under warming climate scenarios.

TL;DR: Wang et al. as mentioned in this paper established runoff plots with two slope gradients (5° and 15°) in north of Yan'an, one area of the Loess Plateau, with 3 single land-use types (cultivated land, CL; switchgrass, SG; and abandoned land, AL).

TL;DR: In this paper, the authors summarized the mycorrhizal status in wetlands and the effect of flooding on AM fungal colonization, and concluded that the functions of AM fungi in wetland ecological systems could be concluded as their influences on the composition, succession, and diversity of the wetland plant community.

TL;DR: In this article, the impact of land use change on heavy metal and arsenic geochemistry by the reclamation of wetlands for agriculture, surface soils and soil profiles were collected from the agricultural land reclaimed in the 1990s and the intertidal flat wetland at Dongtan on Chongming Island in the Yangtze River Estuary, China.

TL;DR: In this paper, the authors investigated the effect of gypsum application on the efficiency of N fertilizer in no-till corn (Zea mays L.) production in southern Brazil.

TL;DR: In this paper, the effects of slope aspects on soil biogeochemical properties and plant communities in forested environments have been studied extensively; however, slope aspect influence on soil microbial communities remains largely unexamined, despite the central role of soil biota in ecosystem functioning.

TL;DR: In this paper, a long-term (over 20 years) experimental field study, started in 1989, was conducted to investigate the changes in soil Se fractions and its uptake by crops, as affected by different fertilizer practices, in the North China Plain with an annual crop rotation of winter wheat and summer maize.

TL;DR: In this article, a review highlights a number of measurements for improving risk calculation methods and expounds scientific approaches that involve the identification of the major source of contamination, exposure pathways and bioavailability of metals.

TL;DR: This study provided the first evidence that AM fungi colonized the roots of pakchoi and indicated the potential application of AMF in the safe production of vegetables in Pb or Cd contaminated soils.

TL;DR: In this article, a review focusing mainly on the responses of soil microbes to climate changes and subsequent effects on soil carbon dynamics is presented, which summarizes the effects of different ecosystems under various experimental treatments on extracellular enzyme activities.

TL;DR: Wang et al. as discussed by the authors used the deviation of arch (DOA)-based regression and partial least squares regression (PLSR) to predict soil organic matter (SOM) in the case of various dataset divisions.

TL;DR: In this article, the authors compared the usefulness of binary logistic regression (BLR) and analytical hierarchy process (AHP) for the assessment of landslide susceptibility over a 130-km2 area in the Moldavian Plateau (eastern Romania) region, where landslides affect large areas and render them unsuitable for agriculture.

TL;DR: In this article, the effects of different fertiliser practices on soil aggregate stability and iron (Fe) and aluminium (Al) oxide contents were investigated in a 26-year long-term fertilisation experiment in greenhouse in Shenyang, China, under eight fertiliser treatments: manure (M), fertiliser N (FN), fertilizer N with manure (MN), fertilizer P (FP), fertilizer P with manure, fertiliser NP (FNP), and control without any fertiliser (CK), and a wet sieving method was used to determine aggregate size distribution and water-

TL;DR: In this article, the results showed that the NEK extracted by NaBPh4 gradually increased with time, but showed no more increase after the duration of extraction exceeded 10−20 d.
