Large - scale agriculture is changing the makeup of
microbes in the
soil, rendering it less biologically diverse.
In an effort to detect consistent patterns across a
large geographical area, University of Illinois researchers conducted a meta - analysis of 62 studies examining the effect of tillage on
soil microbes.
THE rise in atmospheric carbon dioxide predicted for this century could blunt the appetite of
soil microbes that consume a
large chunk of atmospheric methane, adding to the greenhouse effect, claim researchers in North Carolina.
This redistribution of
soil carbon storage raises questions of whether the balance provided by
larger plants will stand in the long term or whether the more active
microbes detected in the deeper
soils will eventually offset the increased carbon in those deeper
soils.
Radishes fed fertilizer by
microbes in the
soil (right) grow
larger than their counterparts without the bugs.
Now, researchers have engineered
microbes that, when added to
soil, make fertilizer on demand, producing plants that grow 1.5 times

large part how the planet stores carbon, when and how carbon is released into the environment, how plants take up nutrients and how crops fare.
Larger proportions of
soil microbes (e.g. Actinobacteria) were observed in the cortices of the coprolites, which were likely due to environmental contamination, whereas smaller proportions were seen in the corresponding cores.

soil microbes adapt genetically to nutrient changes in the
soil.
By building raised beds which are NEVER walked on, heavily mulched and fed by top dressings of
large amounts of organic matter, proponents of no - dig gardening say it protects vital
soil life including worms,
microbes and mychorrizal fungi which all play a part in maintaining
