Special Issue Information
Precision agricultural irrigation often conserves water and contributes to production. However, surface or near-surface precision irrigation systems require new innovative technologies designed to uniformly redistribute additional non-gravitational water in plant root zones that elevate root water uptake efficiencies (RWUEs). Non-uniform root-zone soil water coupled with heterogenous nutrient distributions are major deficiencies associated with precision irrigation. The best soil–plant atmosphere monitoring models coupled with soil water meters and aerial multi-spectral monitoring devices digitally controlling initiation, termination, and rates of precision irrigation fail to avoid multiple plant water deficits. Therefore, new innovative technologies designed to more uniformly distribute soil water, nutrients, and oxygen in plant root zones and determine water and nutrient deficits earlier during multiple crop growth stages are needed before precision irrigation can significantly expand production and improve water and nutrient conservation while protecting the environment.

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.
