Special Issue Information

Dear Colleagues,

Healthy soils are the keystone of sustainable agricultural production and an essential resource to ensure human welfare. Agricultural soils are responsible for ecological functions and services that traditionally include the provision of food and fibers, nutrient cycling, maintenance of biogeochemical cycles, and pest and disease suppression, among others. Soil health, indeed, embraces the continuous capacity of soils to maintain their functions and services for future generations. Further attributes of healthy soils include:

  • Reduced GHG emissions from direct and indirect agricultural sources;
  • Improved water and carbon storage, enhancing soil fertility;
  • Management of agricultural soils to reduce soil erosion;
  • New trends in the development and application of fertilizers and biostimulants;
  • Application of organic wastes from a circular economy perspective;
  • Support of high biodiversity levels of wild organisms (microbiome, flora, and fauna), domestic animals, and crops;
  • Improved quality and quantity of crop yields;
  • Effects of inorganic and organic pollutants on agricultural soils;
  • Physical, chemical, and biological methods to describe healthy soils.

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.

The key plant nutrients determine the crop’s nutritional status and vigor, while their deficiency impairs the plant growth resulting in absolute failure of crop productivity. Phosphorus is the second major essential nutrient for the growth and establishment of crops. Drastic variations in climatic conditions across the world and low soil fertility, especially phosphorous (P) fixation in alkaline calcareous soils of arid climate have become serious issues threatening the productivity of crops. In this regard, the application of different organic fertilizers in combination with the lower dose of chemical fertilizers has been proved as an effective strategy to improve plant growth and yield. Thus, a pot experiment was conducted in order to evaluate the combined effects of animal manures (normal and processed) along with the recommended and half of the chemical fertilizer di-ammonium phosphate (DAP) on the growth, physiology, nodulation, and yield of chickpea. Results show that the animal manure (normal and processed) with half or recommended dose of DAP significantly improved the growth, yield, and physiological attributes of the chickpea. However, the combined application of normal animal manure with half DAP showed the highest results among all other treatments. It increased the contents of leghaemoglobin, P, K, primary branches, pods, and seed weight up to 113.7%, 97.8%, 80.6%, 78.5%, 119%, and 145% over control, respectively. This treatment also increased protein contents, nodule count, and nodule weight up to 78.38%, 147%, and 93.59% than the control, respectively. Maximum chlorophyll b contents (0.78 μg/mL) were obtained with the application of a recommended dose of DAP alone. These indigenous manure applications provide a novel value addition that is critical to boosting crop yield and agricultural sustainability. Full article

Poultry litter and fertilizers are normally added as soil amendments. The effects of poultry litter and inorganic fertilizers on three mixed-season perennial forages were studied for two years in the field to understand growth dynamics, metals, and nutrient uptake. The primary objective was to investigate the heavy metal and nutrient concentrations, biomass yield and forage potential of a cool-season forage, stinging nettle (Urtica dioica L.), relative to warm-season forages, bermudagrass (Cynodon dactylon (L.) Pers.) and switchgrass (Panicum virgatum L.). Forage cuttings and soil samples were analyzed for heavy metals and nutrients using inductively coupled plasma-optical emission spectroscopy (ICP-OES). Total biomass yield was higher by 66% and 50% in switchgrass and bermudagrass, respectively, compared with stinging nettle for the first year. While the warm-season forages yielded more biomass over the cool-season forage, metal concentrations were significantly higher for all elements in the cool-season forage. Stinging nettle showed greater macro-nutrient uptake with 103.20 kg ha−1, 0.87 kg ha−1, 27.49 kg ha−1 and 32.08 kg ha−1 for Ca, Fe, Mg, and P, except for K with 223.51 kg ha−1 compared with 267.29 kg ha−1 and 283.96 kg ha−1 for switchgrass and bermudagrass, respectively. Heavy metals were also higher in stinging nettle but were within the allowable limits for forages, indicating its potential as a resource for forages and nutrient cycling, particularly when double-cropped with warm-season forages.
