While most vegetation types must extract most of their nutrients from fertile soil, mesquites and similar plants receive additional nitrogen from symbiotic bacteria, which enzymatically fix ...

Associative and symbiotic nitrogen-fixing microorganisms obtain these compounds from their host plants’ rhizospheres (National Research Council 1994, Hubbell & Kidder 2009). Industries use the ...

Too wet for planting? Let’s talk cover crops. Is it just me, or does it seem like we’re living in the middle of a wetland? It has been common this spring to see farmers skirting around ...

Atmospheric nitrogen must first be converted, or 'fixed,' into a form that can be used by plants, often as ammonia. There are only two ways of fixing nitrogen, one industrial and one biological.

For example, root exudates from legume plants (e.g., peas, clover, soybeans) serve as a signal to certain species of Rhizobium, which are nitrogen-fixing bacteria. This signal attracts the ...

In the wetland, nitrogen and phosphorus are removed from the surface water and transferred to the sediment, wetland plants or atmosphere. Some agricultural pesticides used in the Midwest can also be ...

The edited versions boost the activity of a key gene involved in nitrogen fixation, making more of it available to plants. When applied at planting, the bacteria colonize plant roots, delivering ...

While the restoration of natural areas is high on political agendas, a comprehensive new study from the University of ...

Field trials on nitrogen-fixing microbes in corn have yet to show reliable benefits, but work continues on their potential of reducing corn's high demand for the nutrient.

Nitrogen-fixing plants: These are species that enrich ... These are plants that are adapted to low-water conditions. 6. Wetland plants: These plants are especially suitable for waterlogged or ...

It’s a problem all earthly life forms must solve: where to get nitrogen? From plants to people, the element is a crucial ... a process called nitrogen fixation, so that it can then be used to build ...
