Abstract

Sustainable irrigation expansion is pivotal to guarantee global food security. Fertigation techniques with surface or subsurface drip lines are among the most promising irrigation practices. Yet, the effect of surface versus subsurface drip fertigation on ecosystem respiration (CO2) fluxes remains largely unknown while there is not available information regarding CH4 emissions, even though this knowledge is essential to obtain a comprehensive overview of the carbon (C) footprint of these practices. To address this knowledge gap, a field experiment was set up in a maize (Zea mays L.) crop comparing surface and subsurface drip (buried at 30 cm depth) in combination with four fertilization treatments (unfertilized control, calcium nitrate and ammonium sulphate with or without the nitrification inhibitor DMPP). Our results showed that all fertilized treatments (except the unfertilized control) were net CH4 sources (135–208 g C ha−1). Subsurface irrigation reduced cumulative CH4 emissions compared to surface irrigation by 80% (P < 0.05). Moreover, subsurface irrigation also abated ecosystem respiration fluxes (by 41%, P < 0.05) relative to surface irrigation. Emission peaks of both C fluxes were observed after fertigation events. Our results demonstrate that subsurface irrigation is a water-saving strategy that can contribute to decreasing the net greenhouse gas emissions of irrigated croplands through the abatement of CH4 and respiration fluxes.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Agricultural Water Management due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2023, it was in position 6/126, thus managing to position itself as a Q1 (Primer Cuartil), in the category Agronomy. Notably, the journal is positioned above the 90th percentile.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 2.64. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 13, 2025)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 2.5 (source consulted: FECYT Mar 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2026-02-17, the following number of citations:

  • WoS: 11
  • Scopus: 13
  • Google Scholar: 2

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-02-17:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 27.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 27 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: https://oa.upm.es/81282/

As a result of the publication of the work in the institutional repository, statistical usage data has been obtained that reflects its impact. In terms of dissemination, we can state that, as of
