Highlights
Denitrification, the main microbial reduction process of nitrate to the inert dinitrogen gas or to reactive gases such as nitric oxide and nitrous oxide [1], is a pivotal mechanism in agricultural soils, since it is the main attenuation mechanism for nitrate leaching towards groundwater [2,3,4]
Advances in Understanding Denitrification in Agricultural Soils. This special issue of the Earth Sciences and Geography section of Applied Sciences sought to collect studies in the areas of soil denitrification and related water quality issues. This is a specific topic characterized by different aspects and facets, such as atmospheric pollution due to greenhouse gases, surface water eutrophication, groundwater pollution by nitrate, and plant–soil interactions
For the above-mentioned reasons, the papers in this special issue provide an overview of the different points of view that different disciplines can use to tackle this global issue
Summary
Denitrification, the main microbial reduction process of nitrate to the inert dinitrogen gas or to reactive gases such as nitric oxide and nitrous oxide [1], is a pivotal mechanism in agricultural soils, since it is the main attenuation mechanism for nitrate leaching towards groundwater [2,3,4]. Denitrification rates are challenging to estimate in the field, given large uncertainties due to measurement techniques and the absence of long-term measurements in different environmental and management settings in agricultural fields [5]. It is acknowledged that major controls of denitrification might be directly or indirectly affected by plants and soils in agricultural systems [6]
