Phosphorus and Micronutrient Interactions in Soils

Dear Colleagues, 

Plant nutrient deficiencies can inhibit yield and crop quality, especially where fertilizers are unaffordable or unavailable. Phosphorus accounts for about 25% of fertilizer use. Its use is dramatically increasing in developing regions, but rarely accompanied with micronutrients in these areas. However, high phosphorus rates can induce deficiencies of certain micronutrients.

In developed agricultural areas, fertilization helped initiate the Green Revolution resulting in steady yield increases that continue to this day. Generally, fertilization is not keeping pace with nutrient removal, which decreases soil fertility. In response, growers increase fertilizer rates, potentially causing negative impacts for micronutrients due to phosphorus and vice-versa.

In other situations, excessive applications of manure or other nutrient-rich inputs cause nutrient pollution and, again, potential interactions between nutrients. How prevalent are these problems? What is the cause of phosphorus–micronutrient interaction? What is the impact on plant growth and the environment? What are the solutions?

This Special Issue focuses on “Phosphorus and Micronutrient Interactions in Soil”. We welcome novel research or reviews on related topics, including soil physical chemistry or biology, genetics, physiology, management, modeling, and case studies.

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.
