Open AccessReducing chemical inputs in agriculture requires a system change
Many countries have implemented policies to reduce the use of chemical inputs in agriculture. However, these policies face many obstacles that limit their effectiveness. The purpose of this paper is to review ...

Open AccessGlobal critical soil moisture thresholds of plant water stress
During extensive periods without rain, known as dry-downs, decreasing soil moisture (SM) induces plant water stress at the point when it limits evapotranspiration, defining a critical SM threshold (θcrit). Better...

Open AccessGlobal spatially explicit yield gap time trends reveal regions at risk of future crop yield stagnation
Yield gaps, here defined as the difference between actual and attainable yields, provide a framework for assessing opportunities to increase agricultural productivity. Previous global assessments, centred on a...

Open AccessHigh temperature sensitivity of monoterpene emissions from global vegetation
Terrestrial vegetation emits vast amounts of monoterpenes into the atmosphere, influencing ecological interactions and atmospheric chemistry. Global emissions are simulated as a function of temperature with a ...

Open AccessAn experimental dataset on yields of pulses across Europe
Future European agriculture should achieve high productivity while limiting its impact on the environment. Legume-supported crop rotations could contribute to these goals, as they request less nitrogen (N) fer...

Open AccessSynthesising results of meta-analyses to inform policy: a comparison of fast-track methods
Statistical synthesis of data sets (meta-analysis, MA) has become a popular approach for providing scientific evidence to inform environmental and agricultural policy. As the number of published MAs is increas...

Simple random forest classification algorithms for predicting occurrences and sizes of wildfires
In order to formulate effective fire-mitigation policies, it is important to understand the spatial and temporal distribution of different types of wildfires and to be able to predict their occurrence taking t...

Warming reduces global agricultural production by decreasing crop** frequency and yields
Annual food caloric production is the product of caloric yield, crop** frequency (CF, number of production seasons per year) and cropland area. Existing studies have largely focused on crop yield, whereas ho...

Open AccessA yield comparison between small-plot and on-farm foliar fungicide trials in soybean and maize
Agronomic research provides management recommendations based on small-plot trials (SPTs) and on-farm trials (OFTs) with very different characteristics. SPTs are traditionally conducted at agricultural experime...

Open AccessChanges in soil carbon mineralization related to earthworm activity depend on the time since inoculation and their density in soil
Earthworms play a key role in soil carbon mineralization, but their effect is highly uncertain and suspected to vary as a function of several factors, particularly the earthworm density and time from earthworm...

Open AccessLong-term K fertilization effects on soil available K, grain yield, and plant K critical value in winter wheat
This study takes advantage of Swiss long-term field experiments (> 30 yrs) with different K fertilization rates at three sites to (i) test the possibility to generalize linear relationships between K extracts ...

Open AccessA global dataset to parametrize critical nitrogen dilution curves for major crop species
Precise management of crop nitrogen nutrition is essential to maximize yields while limiting pollution risks. For several decades, the critical nitrogen (N) dilution curve - relating plant biomass (W) to N con...

The critical benefits of snowpack insulation and snowmelt for winter wheat productivity
How climate change will affect overwintering crops is largely unknown due to the complex and understudied interactions among temperature, rainfall and snowpack. Increases in average winter temperature should r...

Data-driven projections suggest large opportunities to improve Europe’s soybean self-sufficiency under climate change
The rapid expansion of soybean-growing areas across Europe raises questions about the suitability of agroclimatic conditions for soybean production. Here, using data-driven relationships between climate and so...

Open AccessPrinciples and framework for assessing the risk of bias for studies included in comparative quantitative environmental systematic reviews
The internal validity of conclusions about effectiveness or impact in systematic reviews, and of decisions based on them, depends on risk of bias assessments being conducted appropriately. However, a random sa...

Open AccessAtmospheric dryness reduces photosynthesis along a large range of soil water deficits
Both low soil water content (SWC) and high atmospheric dryness (vapor pressure deficit, VPD) can negatively affect terrestrial gross primary production (GPP). The sensitivity of GPP to soil versus atmospheric ...

Open AccessA global dataset for the projected impacts of climate change on four major crops
Reliable estimates of the impacts of climate change on crop production are critical for assessing the sustainability of food systems. Global, regional, and site-specific crop simulation studies have been condu...

Open AccessDecision support systems halve fungicide use compared to calendar-based strategies without increasing disease risk
The European Green Deal aims to reduce the use of chemical pesticides by half by 2030. Decision support systems are tools to help farmers schedule fungicide spraying based on disease risk and can reduce fungic...

Tradeoff of CO2 and CH4 emissions from global peatlands under water-table drawdown
Water-table drawdown across peatlands increases carbon dioxide (CO2) and reduces methane (CH4) emissions. The net climatic effect remains unclear. Based on global observations from 130 sites, we found a positive ...
