Special Issue Information

Dear Colleagues,

Nowadays, the most important issue in the realization of efficient agriculture is realizing a sustainable approach to farming based on organic production. For this purpose, the replacement of chemical fertilizers and pesticides with environmentally friendly alternatives is widely promoted. Thus, biotechnologies encourage a reduction in the chemicalization of agriculture by introducing biofertilizers, biopesticides, and bioherbicides. Methods to stimulate the biological productivity of soils using digestates after the anaerobic digestion of sustainable feedstock are also being called for by countries around the world.

In particular, the modern challenges of soil contamination with various pollutants, such as heavy metals, radionuclides, petroleum products, microplastics, etc., dictate the need to implement new methods of soil treatment. At the same time, the bioremediation of soils with the aim to return them to the agricultural use system is an important issue. Thus, biochar is used in this direction to restore soil microbial activity.

In general, the sustainable development of agriculture cannot be imagined without the support of biotechnology and bio-based products that can be produced using waste with its valorization.

This Microorganisms Special Issue, "Advances in Agro-Microbiology", will present the latest advances and innovative research in the field of agrobiology, with a focus on the development of a sustainable approach to farming and the introduction of bio-based products to stimulate the soil microbiome and improve agricultural yields.Some of the focal points include, but are not limited to, the following:

  1. Biofertilization and the role of the microbiome in sustainable agriculture.
  2. Microbial interactions in agricultural systems.
  3. Biopesticides and bioherbicides and their role in sustainable agriculture.
  4. Introduction of digestates after anaerobic digestion in organic farming.
  5. Carbon sequestration in the soil under digestate application.
  6. Bioremediation of soils to return them to the agricultural system.
  7. Restoration of microbial activity of soils by biochar.

In order to explore the effects of different silage inoculants on the silage quality of alfalfa (Medicago sativa L.), this study utilized six groups of experimental treatments and five kinds of additive treatments: Xinlaiwang I straw silage (group A), Xinlaiwang I alfalfa silage (group B), Zhuanglemei silage starter culture (group C), Baoshiqing (group D), Kangfuqing S lactic acid bacteria silage (group E), and another blank control group (CK group, distilled water). The effect of silage on fermentation characteristics and nutritional value of Adina alfalfa silage was studied by membership function analysis. The main study variable was inoculant strains. Alfalfa silage was packed into polyethylene plastic vacuum bags in the laboratory and sealed for 60 days. The silage was divided into six treatment groups with three replicates per group. The fermentation performance and nutrient composition of the silage were determined. The results showed that compared with the control group, adding Xinlaiwang I alfalfa silage (group B) could significantly increase the contents of crude protein (CP) and lactic acid (LA) in alfalfa silage (p < 0.05), decrease the contents of neutral detergent fiber (NDF) and acid detergent fiber (ADF), and decrease the pH and ammoniacal nitrogen/total nitrogen (AN/TN). The results showed that different inoculants could improve the silage quality of alfalfa to different extent, and Xinlaiwang I alfalfa silage had the best effect. Full article

The efficiency and consistency of biologicals in the field remain a drawback of current conventional products. The development of systemic biological products has opened a new avenue for microbiological and agricultural research. In this study, we evaluated over a two-year period (2022 and 2023) the functioning of two systemic products, a biofertilizer and biofungicide, on the performance of the onion. The first indicator of proper functioning of these products in onions was reflected in increased chlorophyll accumulation. At the end of both years, the inoculated plants were taller, heavier, and developed more leaves than their control counterparts (p < 0.5). Inoculated onion bulbs collected at harvest time were significantly heavier (45.1% in 2022 and 56.2% in 2023) than their non-inoculated counterparts (p < 0.5). Onion quality, expressed in terms of total soluble solids and pyruvic acid content, was also significantly improved in plants inoculated with the biological products; the two-year average values for these quality variables were 10.2 vs. 14.4°Brix and 2.3 vs. 4.0 µmol∙g−1 for control and biologically treated plants, respectively. The two-year average fungal incidence was 1.9 times greater in the control group than in the inoculated plants, while the average onion yield for this period was 44.7% higher (p < 0.5) in the biologically treated plot (54.7 t∙ha−1) than in the control one (37.8 t∙ha−1). Based on comparisons with previous studies employing conventional biologicals, our results demonstrate the superior effectiveness of the systemic biologicas in improving onion performance.
