Special Issue Information

Dear Colleagues,

Agricultural activities from animal production and crop production are becoming increasingly scrutinized due to their impacts on the atmosphere. Agricultural contributions to air quality issues include greenhouse gases (methane and nitrous oxide), odor compounds (several classes of volatile organic compounds), the primary production of particulate matter from tillage and harvesting, dust and bioaerosols from animal housing, combustion aerosols from controlled burns, and precursor emissions, which can lead to secondary atmospheric chemistry and regional deposition effects (i.e., ammonia, amines, sulfur compounds, and nitric oxide). There has been some progress in the characterization of emissions from agricultural sources, yet significant uncertainties remain for many compounds. Emission inventories and models are in many ways incomplete at local, national, and international levels, making it difficult to test mitigation strategies in a comprehensive way. Even so, some newer approaches to manure management, such as anaerobic digesters or the wider conversion of waste to biochar, show promise for reducing agricultural emissions and returning at least some of them to the circular economy. Other mitigation strategies such as atmospheric scrubbers have shown technological feasibility, but still struggle to be economically viable. This Special Issue welcomes papers that focus on all aspects of the interaction between agriculture and the atmosphere. Measurement- and modeling-oriented papers that examine emissions from agricultural sources, the factors governing the emission process, mitigation methods, and economic feasibility, are encouraged.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Concerns about atmospheric ammonia have been expressed recently by some on the Lower Eastern Shore (LES) of Maryland, which lies between the Chesapeake Bay and the Atlantic Ocean on the Delmarva peninsula. Agriculture, seafood and tourism are responsible for a significant fraction of the economic activity on the LES. The USDA 2017 census reported there were ~100 Concentrated Animal Feeding Operations (CAFOs) raising nearly 63 M chickens per year across Somerset and Worcester Counties. We report air quality data collected from sites near Princess Anne, Somerset County, and near Pocomoke City, Worcester County, to address air quality concerns by examining the influence of chicken farms on ammonia in ambient air on the LES. Within a two-mile radius of the Worcester County site, CAFO operations house ~1.6 million birds. The Princess Anne site is comparable to the Pocomoke City site in agricultural use and population demographics but has only a few chicken houses within two miles. The first 33 months of LES ammonia data are presented, and their significance is discussed relative to other ammonia studies. The 33-month average concentration of ammonia in Pocomoke was 10.3 ± 0.08 ppb, more than double that in Princess Anne, which was 4.7 ± 0.04 ppb. Full article
