Special Issue Information

Dear Colleagues,

Cover plants (such as Poaceae and Fabaceae) and animal manure (such as swine, cattle, and poultry) may be used as nutrient sources for annual and perennial crops, increasing the nutrient cycling within agricultural land and reducing the costs with the acquisition of industrial fertilizers. Additionally, over the years, it is expected to modify chemical soil attributes, such as increasing the carbon and nitrogen content in the soil, which can affect crop productivity and impact the environment.

Thus, we invite researchers to contribute original papers and review articles about using cover plants and animal manure as fertilizer, investigating the effect on changes in soil carbon and nitrogen content and stocks, with application periods in the soil of at least five years of animal manure or use cover plants.

Potential topics include but are not limited to the following:

  • Soil carbon and nitrogen with a history of cover plant utilization in succession or rotation crops;
  • Soil carbon and nitrogen with a history of animal manure applications;
  • Fractions and accumulation of carbon and nitrogen in areas with soil cover plants that are intercropped or single;
  • Fractions and accumulation of carbon and nitrogen in areas with animal manure applications;
  • Soil carbon and nitrogen in soil aggregates with a use history of cover plants or animal manure.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Organic amendments are important sources of nutrients that release upon organic matter degradation, yet the stability of these organics in arid and semi-arid regions is relatively low. In contrast, humic substances (HS) are resistant to biodegradation and can keep nutrients in the soil available for the plant over a long time. Combinations between humic substances (HS) and mineral-N fertilizers are assumed to retain higher available nutrients in soils than those recorded for the sole application of either mineral or organic applications. We anticipate, however, that humic substances might not be as efficient as the organics from which they were extracted in increasing NP uptake by plants. To test these assumptions, faba bean was planted in a pot experiment under greenhouse conditions following a complete randomized design while considering three factors: two soils (calcareous and non-calcareous, Factor A), two organics (biogas and compost, Factor B) and combinations of the organics and their extracts (HA or FA) together with complementary doses of mineral-N ((NH4)2SO4) to attain a total rate of 50 kg N ha−1 (the recommended dose for faba bean plants) (Factor C). Results indicated that nitrogenase activity increased significantly due to the application of the used organics. In this respect, compost manure caused higher nitrogenase activity than biogas manure did. Humic substances raised NP-availability and the uptake by plants significantly; however, the values of increase were lower than those that occurred due to the compost or biogas manure. Moreover, the sole application of the used organics recorded the highest increases in plant biomass. Significant correlations were also detected between NP-availability, uptake and plant biomass. This means that HS could probably retain nutrients in available forms for long time periods, yet nutrients released continuously but slowly upon decomposition of organics seemed more important for plant nutrition.
