Rothamsted Research, North Wyke, Devon, EX20 2SB, UK.

High ammonia (NH) emissions from fertilized soil in China have led to various concerns regarding environmental safety and public health. In response to China's blue skies protection campaign, effective NH reduction measures need to consider both mitigation efficiency and food security. In this context, we conducted a meta-analysis (including 2980 observations from 447 studies) to select effective measures based on absolute (AV) and yield-scaled (YSAV) NH volatilization reduction potential, with the aim of establishing a comprehensive NH mitigation framework covering various crop production sectors, and offering a range of potential solutions.

PLoS One 2021 21;16(7):e0249730. Epub 2021 Jul 21.

Institute of Soil, Fertilizer and Agricultural Water Conservation, Xinjiang Academy of Agricultural Sciences, Urumqi, Xinjiang, China.

Drip irrigation under plastic mulch is widely used in Xinjiang, Northwest China. It can not only save water, but also reduce nutrient loss and improve fertilizer utilization. However, it is not clear whether the leaching occurs or not, what is the leaching amount? What is the relationship among fertilization, irrigation regimes, loss, cotton absorption, and cotton field under different fertilization and irrigation management under drip irrigation? Studying these issues not only provides reference for the formulation of fertilization and irrigation systems, but also is of great significance for reducing non-point source pollution. Read More

Soil organic carbon in irrigated agricultural systems: A meta-analysis.

Glob Chang Biol 2021 08 7;27(16):3898-3910. Epub 2021 Jun 7.

Biology Department, The University of British Columbia Okanagan, Kelowna, BC, Canada.

Over the last 200 years, conversion of non-cultivated land for agriculture has substantially reduced global soil organic carbon (SOC) stocks in upper soil layers. Nevertheless, practices such as no- or reduced tillage, application of organic soil amendments, and maintenance of continuous cover can increase SOC in agricultural fields. While these management practices have been well studied, the effects on SOC of cropping systems that incorporate irrigation are poorly understood. Read More
