Glyphosate Harms Mycology and Earthworm Populations

What role do earth worms play in productive soil life?

A great video about the role of earth worms and their gut bacteria on feeding microbes that help fix nitrogen in soils.

What are humans doing to harm Mycology and Earthworm Populations?

    Humans are harming the soil by:

  • Watering their lawn with tap water high in cholorine with little to no living microbes.
  • Using Round Up to “manage weeds”
  • Using Nitrogen only Fertizlers without microbes to “fertilize their lawns.”

“A profound shift in bacterial populationswas observed in all exposed earthworms with Proteobacteria becoming the dominant phylum. Affected bacteria were mostly from the genus Enterobacter, Pantoea and Pseudomonas, which together represented approximately 80 % of the total abundance assigned at the genus level in exposed earthworms, while they were present at a minor abundance (∼1%) in unexposed earthworms.”

Glyphosate is the main igredient of Round Up, a Monsanto product. Monsanto is owned by Bayer Chemical Company.

“Our findings indicated reduced species number, density and biomass of earthworms, and increased net carbon mineralization rate in plots with GBH. The plots managed with glyphosate presented a negative effect on the earthworm parameters measured, and we conclude that the earthworms therefore acted as indicators of perturbation. It is also possible that this effect could be due to factors unrelated to the glyphosate that were not considered in this study, such as chemical fertilization or legume litter spatial variability, among others.”

Both Nitrogen only fertilizers without microbes, with salt cystals as the main medium to prevent microbal growth produced by Bayer, as well as Round Up are contributing to the decline of life activity in our soils world wide.

“We found that herbicides significantly decreased root mycorrhization, soil AMF spore biomass, vesicles and propagules. Herbicide application and earthworms increased soil hyphal biomass and tended to reduce soil water infiltration after a simulated heavy rainfall. Herbicide application in interaction with AMF led to slightly heavier but less active earthworms. Leaching of glyphosate after a simulated rainfall was substantial and altered by earthworms and AMF. These sizeable changes provide impetus for more general attention to side-effects of glyphosate-based herbicides on key soil organisms and their associated ecosystem services.”

Abstract

Endophytes are microbial symbionts living inside plants and have been extensively researched in recent decades for their functions associated with plant responses to environmental stress. We conducted a meta-analysis of endophyte effects on host plants’ growth and fitness in response to three abiotic stress factors: drought, nitrogen deficiency, and excessive salinity. Ninety-four endophyte strains and 42 host plant species from the literature were evaluated in the analysis. Endophytes increased biomass accumulation of host plants under all three stress conditions. The stress mitigation effects by endophytes were similar among different plant taxa or functional groups with few exceptions; eudicots and C4 species gained more biomass than monocots and C3 species with endophytes, respectively, under drought conditions. Our analysis supports the effectiveness of endophytes in mitigating drought, nitrogen deficiency, and salinity stress in a wide range of host species with little evidence of plant-endophyte specificity.
