Special Issue Information

Dear Colleagues,

Grasslands are a unique ecosystem which occupies more than a quarter of the land surface of the Earth, providing numerous ecosystem services including forage provision, nutrient cycling, carbon sequestration, water filtration, biodiversity, and wildlife habitats. In terms of their origins, permanent grasslands have been established for agricultural purposes on areas that would otherwise be occupied by forests. Consequently, the soils on which they have been created are also diverse and have different textures and physical, chemical, and biological properties. Beyond these permanent grasslands, temporary ley grasslands are a vital part of crop rotation exerting a positive influence on soil ecosystem services.

Healthy soils, as a non-renewable source, are key to ensuring grassland ecosystem services. Climate change and management, such as the intensity of fertilization, overgrazing, or abandonment, are two major factors that affect soil properties and consequently grassland ecosystem services.

This Special Issue will focus on studies and analyses of the impact of grassland management and climate change on the chemical, physical, and biological properties of soils. Therefore, manuscripts and long-term studies aimed at assessing changes in soil organic matter, soil acidity and nutrient content, and soil biota evaluation are all welcome.

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.

Phosphorus is one of the major constraints to karst grassland productivity. Understanding the effects of different fertilization practices on soil phosphorus dynamics is essential for enhancing phosphorus bioavailability and rational management of soil phosphorus in karst grasslands. Here, we investigated the effects of fertilizers and manures on soil bioavailability of phosphorus fractions and explored the relationship between soil properties and soil phosphorus fractions. The four fertilizer application designs were as follows: control (CK; no fertilizer or manure); fertilization (F); manure application (M); fertilization and manure application (FM). The results showed that total phosphorus (TP) concentration was elevated by 23%, 1%, and 42% in F, M, and FM treatments, respectively, compared with CK. F and FM treatments enhanced the total inorganic phosphorus (Pi) concentration by 65% and 66%, respectively, while M and FM treatments enhanced the total organo-phosphorus (Po) concentration by 21% and 35%, respectively. FM treatment elevated bioavailable P, active Po, secondary mineral P, primary mineral P, and occluded P by 69%, 39%, 50%, 31%, and 41%, respectively. Fertilizers inhibited soil acid phosphatase activity, whereas alkaline phosphatase did not respond significantly to fertilizer management in low-latitude karst regions. SOM, TN, AP, and MBP are the key factors affecting the bioavailability of phosphorus fractions. The combined application of fertilizer and manure is the most beneficial measure for enhancing soil phosphorus bioavailability. This research helps deepen our understanding of soil phosphorus dynamics in the karst areas and provides a basis for further enhancement of nutrient availability and vegetation productivity of grassland ecosystems.

Title: Management practices in mountain meadows: consequences on soil nutrient availability.
Authors: Adrián Jarne, Asunción Usón and Ramón Reiné
Affiliation: Department of Agrarian and Environmental Sciences. University of Zaragoza, Spain.
Abstract: Mountain meadows are the most important source of food for extensive livestock farming, as well as providing important environmental services. In year 2022 and 2023 we have carried out an exhaustive monitoring of the agricultural management of 12 mowing meadows representative of the different practices applied in these plant communities in the central Spanish Pyrenees. We have characterized organic fertilization (manure or slurry), inorganic fertilizers, grazing times and intensities and grass production at mowing time. Also, we sampled soils, mineral extractions at harvest, bromatological quality and plant diversity. By carrying out a balance between the main elements on soils (C, N, P and K). We aim to draw conclusions about the productive potential and the conservation of plant diversity in the meadows.
