Bacteria and fungi can contribute to nutrients bioavailability and aggregate formation in degraded soils
Open accessAbstract
Intensive agricultural practices and cultivation of exhaustive crops has deteriorated soil fertility and its quality in agroecosystems. According to an estimate, such practices will convert 30% of the total world cultivated soil into degraded land by 2020. Soil structure and fertility loss are one of the main causes of soil degradation. They are also considered as a major threat to crop production and food security for future generations. Implementing safe and environmental friendly technology would be viable solution for achieving sustainable restoration of degraded soils. Bacterial and fungal inocula have a potential to reinstate the fertility of degraded land through various processes. These microorganisms increase the nutrient bioavailability through nitrogen fixation and mobilization of key nutrients (phosphorus, potassium and iron) to the crop plants while remediate soil structure by improving its aggregation and stability. Success rate of such inocula under field conditions depends on their antagonistic or synergistic interaction with indigenous microbes or their inoculation with organic fertilizers. Co-inoculation of bacteria and fungi with or without organic fertilizer are more beneficial for reinstating the soil fertility and organic matter content than single inoculum. Such factors are of great importance when considering bacteria and fungi inocula for restoration of degraded soils. The overview of presented mechanisms and interactions will help agriculturists in planning sustainable management strategy for reinstating the fertility of degraded soil and assist them in reducing the negative impact of artificial fertilizers on our environment.

In terrestrial soils, Microcoleaceae contribute to soil aggregation and stability.
“In terrestrial soils, they contribute to soil aggregation and stability (Rashid et al., 2016), increase the water-holding capacity and nutrient content of degraded soils (Singh et al., 2016), and enhance salt tolerance, disease resistance, and polysaccharide production (Singh, 2014).”
From Spirulina supported plant growth in regolith simulants and elevated levels of CO2 (2025) · cites this paper as Rashid et al., 2016
Sections 4.1 and 4 describe how bacteria contribute to soil aggregate formation and stability. The paper does not identify Microcoleaceae or establish that this particular family has that role; the citation supports the general mechanism, not the taxon-specific claim. (LLM, conf=0.85)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
