The Effects of Mulch and Nitrogen Fertilizer on the Soil Environment of Crop Plants
Xiukang Wang,Junliang Fan,Yingying Xing,Guoce Xu,Haidong Wang,Jian Deng,Yanfeng Wang,Fucang Zhang,Peng Li,Zhanbin Li +9 more
TL;DR: In this paper, the effects of mulching and nitrogen (N) fertilizer on the soil environment and crop yield to inform food security are discussed. But, the use of mulch in agriculture provides many benefits to the soil by reducing evaporation, improving temperatures, adjusting the microbial biomass, maintaining the soil organic carbon balance, increasing nutrient cycling, promoting soil enzyme activity, enhancing soil aggregate stability and suppressing weed infestation.

Distribution characteristics of residual film over a cotton field under long-term film mulching and drip irrigation in an oasis agroecosystem
Huaijie He,Huaijie He,Zhenhua Wang,Zhenhua Wang,Li Guo,Xurong Zheng,Xurong Zheng,Jinzhu Zhang,Jinzhu Zhang,Wenhao Li,Wenhao Li,Bihang Fan +11 more
TL;DR: Wang et al. as discussed by the authors examined the distribution characteristics of residual plastic film (RPF) in the topsoils (0-40 cm) in an oasis agroecosystem in Northwest China.
Journal ArticleDOI
A meta-analysis of film mulching cultivation effects on soil organic carbon and soil greenhouse gas fluxes
TL;DR: In this paper, a meta-analysis compiling data from 150 studies was used to assess the effects of film mulching on organic carbon (SOC) and soil GHG fluxes across different agricultural systems.
Journal ArticleDOI
Modeling impacts of mulching and climate change on crop production and N2O emission in the Loess Plateau of China
TL;DR: In this article, the authors applied a biogeochemical model, DeNitrification-DeComposition (DNDC), to predict impacts of different mulching practices on wheat yields and N2O emissions under future climate scenarios in the South Loess Plateau of China.

Year-round plastic film mulch to increase wheat yield and economic returns while reducing environmental risk in dryland of the Loess Plateau
Gang He,Gang He,Zhaohui Wang,Zhaohui Wang,Hanbing Cao,Hanbing Cao,Jian Dai,Jian Dai,Qiang Li,Qiang Li,Cheng Xue,Cheng Xue +11 more
TL;DR: In this article, a location-fixed field experiment was performed to determine the effect of year-round plastic film mulch (YPM, mulching soil surface with plastic film during the growing season and fallow season of winter wheat) on wheat yield, environment (nitrate-N leaching and greenhouse gas (GHG) emissions), and economic returns.

Reducing environmental risk by improving N management in intensive Chinese agricultural systems
Xiaotang Ju,Guang-Xi Xing,Xinping Chen,Shao-Lin Zhang,Lijuan Zhang,Xuejun Liu,Zhenling Cui,Bin Yin,Peter Christie,Zhao-Liang Zhu,Fusuo Zhang +10 more
TL;DR: Examination of grain yields and N loss pathways in 2 of the most intensive double-cropping systems in China found that current agricultural N practices with 550–600 kg of N per hectare fertilizer annually do not significantly increase crop yields but do lead to about 2 times larger N losses to the environment.

The role of conservation agriculture in sustainable agriculture.
TL;DR: It is concluded that agriculture in the next decade will have to sustainably produce more food from less land through more efficient use of natural resources and with minimal impact on the environment in order to meet growing population demands.

Carbon sequestration in agricultural soils via cultivation of cover crops – A meta-analysis
Christopher Poeplau,Axel Don +1 more
TL;DR: In this article, the authors conducted a meta-analysis to derive a carbon response function describing soil organic carbon (SOC) stock changes as a function of time and estimated a potential global SOC sequestration of 0.03% of the direct annual greenhouse gas emissions from agriculture.

An agronomic assessment of greenhouse gas emissions from major cereal crops

TL;DR: In this article, the authors conducted a meta-analysis to test the hypothesis that the global warming potential (GWP) of CH4 and N2O emissions from rice, wheat, and maize, when expressed per ton of grain (yield-scaled GWP), is similar, and that the lowest value for each cereal is achieved at near optimal yields.
