Dear Colleagues,

The efficient use of water or fertilizers in agriculture is no longer an option but a requirement. Using the necessary and sufficient resources for agricultural production is the very first principle of sustainability. In recent decades there has been a considerable increase in scientific knowledge about the water and nutritional needs of crops and the response of plants to different irrigation and fertilization strategies. At the same time, the arrival of ICT technologies in agriculture has opened a new window of opportunity for capturing information about the plant, the crop, and its environment, and for managing this information and interpreting it. Will this technological revolution open the door to new agriculture, or have expectations been created that are still far from be realized? Scientific research must lay the bases and offer contrasting information regarding which kind of technological progress is best to support in agriculture.

This Special Issue focuses on research, use, integration, and development in ‘’Use of Soil and Plant Sensors for Monitoring the Water and Nutritional Status of Crops’’ to optimize irrigation and fertilization management for agricultural and horticultural production. Submissions on but not limited to the following topics are invited:

(1) plant-based sensing for water and fertilization stress monitoring,

(2) plant and soil moisture sensors for irrigation management,

(3) monitoring UAV and satellite to precision fertilization and irrigation,

(4) using sensors to automate fertilization and irrigation scheduling,

(5) wireless sensor networks for fertilization and irrigation management,

(6) sensors to estimate actual crop water and nutritional needs,

(7) variable-rate fertilization and irrigation, and

(8) decision-support systems combined with sensors.

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. Water is an international peer-reviewed open access semimonthly 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.
