Contemporary crop production faces dual challenges of increasing crop yield while simultaneously reducing greenhouse gas emission. An integrated evaluation of the mitigation potential of yield-scaled nitrous oxide (N2O) emission by adjusting cropping practices can benefit the innovation of climate smart cropping. This study conducted a meta-analysis to assess the impact of cropping systems and ...

Interannual variation in plant phenology can lead to major modifications in the interannual variation of net ecosystem production (NEP) and net biome production (NBP) as a result of recent climate change in croplands. Continuous measurements of carbon flux using the eddy covariance technique were conducted in two winter wheat and summer maize double-cropped croplands during 2003-2012 in Yucheng...

Recent advances in understanding the role of the El Niño–Southern Oscillation (ENSO) in climate variability present opportunities for improving efficiency in agricultural production. We investigated the relationships between ENSO, climate and maize yields in the U.S. cornbelt, using both observed data and crop simulations. Using a time-series of sea-surface temperature anomalies (SSTA) from the...

Conflicts between water supply and water demand are intensifying in irrigation districts along the Lower Yellow River due to climate change and human activities. To ensure both adequate food supply and water resource sustainability in China, the Soil and Water Assessment Tool (SWAT) model was used to simulate the water balance and water use of agro-ecosystems in an irrigation district of the lo...

The potential effects of future climate change were investigated, corresponding to a doubling of atmospheric CO2 from 350 to 700 ppm, on agricultural production of four different cropping systems at two Italian locations, Modena and Foggia. Climate change scenarios, derived from two general circulation models (GCMs), were used as weather input to a soil-plant growth simulator, CropSyst. This mo...

Leaf Area of Index (LAI) refers to half the total leaf area all crops per unit area. It is an important index represent photosynthetic capacity and biomass crops. To obtain LAI conditions summer maize in different growth stages quickly accurately, further guiding field fertilization irrigation. The Unmanned aerial vehicles (UAV) multispectral data, growing degree days, canopy height model 2020-...

Rapid and accurate crop chlorophyll content estimation the leaf area index (LAI) are both crucial for guiding field management improving yields. This paper proposes an monitoring method LAI soil plant analytical development (SPAD) values (which closely related to content; we use SPAD instead of relative content) based on fusion ground–air multi-source data. Firstly, in 2020 2021, collected unma...

In the production of summer maize, problems excessive fertilizer input and low utilization rate are common, resulting in waste resources environmental pollution. order to explore optimal fertilization mode a field experiment with eight treatments was designed which sowing were carried out by different machines. The effects two methods, i.e., hole strip fertilization; positions, side-position po...
