The latter trend (i.e., lower soil fertility in rehabilitated vs. reference sites) was also found regarding the concentrations of major and minor soil nutrients (e.g., Al, B, Ca, Cl, Cu, Fe, K, Mg, Mn, Na, S, Zn), albeit having no distinct or remarkable trends of their own (data not shown).
Importantly, AM fungi have the ability to connect roots of neighboring plants to form common mycelial networks (CMNs), which have major roles in recycling of soil nutrients and water and regulating plant community dynamics.
Pinus also caused a major shift in soil nutrient cycling as indicated by increased bacterial dominance, NO3-N (17-fold increase) and available phosphorus (3.2-fold increase) in soils, which in turn promoted increased growth of graminoids.
We expected that the establishment of invasive Pinus would cause major shifts in soil nutrient cycling, with increased P availability but also increased fungal dominance and N limitation relative to the predominantly native plant community present when Pinus was excluded (i.e. Seedling-Removal treatment).
Biochar reduces leaching of soil nutrients, saving on inputs, while increasing soil moisture, reducing the need for watering.
Unsustainable farming methods are depleting soil nutrients significantly faster than they can be replenished.
Plants "forage" for resources like light and soil nutrients and "anticipate" rough spots and opportunities.
But its principal crops cotton, tobacco, corn were a tremendous drain on soil nutrients.
But lianas outcompete trees for soil nutrients, water and light.
Soil nutrients are enriched.
