Continuous cropping obstacles (CCOs) cause, on average, 22% reduction in crop production, seriously threatening sustainable agricultural development.• Changes the soil ecological environment are an essential and easily overlooked cause of CCOs.• Studying CCOs from perspective microbial food web may provide new approaches for explaining formation mechanism controlling soilborne pathogens.• Not all continuous systems have CCOs, some enrich beneficial microorganisms to form healthy disease-suppressive soil.

Biodiversity on the Earth is changing at an unprecedented rate due to a variety of global change factors (GCFs). However, effects GCFs microbial diversity unclear despite that soil microorganisms play critical role in biogeochemical cycling. Here, we synthesize 1235 GCF observations worldwide and show rare species are more sensitive than common species, while do not always lead reduction diversity. GCFs-induced shifts alpha can be predominately explained by changed pH. In addition, impacts functionality community structure biomass rather Altogether, our findings fundamentally different from previous knowledge for well-studied plant animal communities, crucial policy-making conservation hotspots under changes.

Soil nitrification, an important pathway of nitrogen transformation in ecosystems, produces soil nitrate that influences net primary productivity, while the by-product nitrous oxide, is a significant greenhouse gas. Although there have been many studies addressing microbiology, physiology, and impacting environment factors nitrification at local scales, are very few on rate over large scales. We conducted global synthesis patterns controlling normalized 25°C by compiling 3,140 observations from 186 published articles across terrestrial ecosystems. tended to decrease with increasing latitude, especially Northern Hemisphere, varied largely ecosystem types.

Abstract Globally, about 50% of all arable soils are classified as acidic. As crop and plant growth significantly hampered under acidic soil conditions, many farmers, but increasingly well forest managers, apply lime to raise the pH. Besides its direct effect on pH, liming also affects C nutrient cycles associated greenhouse gas (GHG) fluxes. In this meta‐analysis, we reviewed 1570 observations reported in 121 field‐based studies worldwide, assess effects GHG fluxes productivity. We found that increases yield by 36.3%. Also, organic (SOC) stocks were increase 4.51% annually, though respiration is stimulated too (7.57%). Moreover, was reduce N 2 O emission 21.3%, yield‐scaled 21.5%, CH 4 from rice paddies 19.0% 12.4%, respectively.

Abstract Soil pH is critically important in regulating soil nutrients and thus influencing the biodiversity ecosystem functions of terrestrial ecosystems. Despite ongoing threat nitrogen (N) pollution especially fast‐developing regions, it remains unclear how increasing N deposition affects across global By conducting a meta‐analysis with paired observations under addition control from 634 studies spanning major types ecosystems, we show that acidification increases rapidly amount most severe neutral‐pH soils. Grassland decreases strongly high while wetlands are least acidified. extrapolating these relationships to mapping, reveal atmospheric leads average decline −0.16 past 40 years regions encompassing Eastern United States, Southern Brazil, Europe, South East Asia hotspots deposition.

Abstract Soil acidification induced by reactive nitrogen (N) inputs can alter the structure and function of terrestrial ecosystems. Because different N‐transformation processes contribute to production consumption H + , magnitude likely depends on relative amounts organic N (ON) inorganic (IN) inputs. However, few studies have explicitly measured effects composition soil acidification. In this study, we first conducted a meta‐analysis test ON or IN across 53 in grasslands. We then compared five ON:IN ratios two input rates based long‐term field addition experiments. The showed that had weaker than when rate was above 20 g m −2 year −1 . experiment confirmed findings from meta‐analysis: with proportions ≥ 20% caused less acidification, especially at high (30 ).
