Sentences with phrase «available nitrogen in»

In the nitrogen cycle, some microbes perform an especially important step: the oxidation of nitrite (NO2 −) to nitrate (NO3 −), the dominant form of biologically available nitrogen in the ocean.

Not exact matches

This process increases nitrogen available in the soil without the need for added fertilizer.

The test, which could be available to patients within two years, identifies the chemical signatures found in the plasma of blood joint proteins damaged by oxidation, nitration and glycation; the modification of proteins with oxygen, nitrogen and sugar molecules.

The authors of a new study say that there has been limited information available about the influence of fertilizer sources of nitrogen that can be injected and fertigated on fruit yield and quality in organic blackberry.

While essential for plant growth, an over-abundance of this biologically - available nitrogen can result in «nitrogen saturation,» a phenomenon previously reported by Forest Service scientists in Riverside.

In that form, says Navarro - Gonzalez, nitrogen was available to create the building blocks of life.

The team suspects that differences in decomposing plant material might have led to changes over time in the community of microbes that process nitrogen in the soil and make it available to plants.

The great benefit is that legumes contribute to cropping systems; they can help take nitrogen out of the atmosphere and make it available in the soil.

In fact, had scientists not created synthetic, mostly natural - gas - based fertilizer decades ago to improve nature's method of «fixing» nitrogen — a process of breaking nitrogen molecules apart to make them available to plants — neither you nor I, nor most of the 7 billion people crowding the planet, would be here today.

For example, bacteria in soil release nitrogen and phosphorus as they break down dead plants, and so these microbes could increase the amount of available nitrogen and phosphorus.

«This increases the nutrients — such as carbon, nitrogen and available phosphorus — in the topsoil.»

Beyond producing hydrogen and carbon - rich fuels in a sustainable way, he has demonstrated that equipping the system with a different metabolically altered bacterium can produce nitrogen - based fertilizer right in the soil, an approach that would increase crops yields in areas where conventional fertilizers are not readily available.

Up to 80 % of the available oxygen, carbon and nitrogen are found in such ices; the most common ice constituents - H2O, CO2 and CO - are second in abundance only to H2 in many star forming regions.

In other words, with more nitrogen available, plant life might be able to absorb more CO2 than climate scientists have been estimating, which means the planet won't warm as much, despite mankind's pumping CO2 into the atmosphere.

As a 2003 study published in the same Science journal put it, «there will not be enough nitrogen available to sustain the high carbon uptake scenarios.»

In a complicated exchange of nutrients, rhizobia produce an abundance of nitrogen, making it available to the plant.

However, the diesel won't cross the pond in the same specification available in Europe, as the SkyActiv - D powerplant has to be tweaked to meet the more stringent U.S. regulations for nitrogen oxide emissions.

All plants need nitrogen, yet the vast pool of nitrogen gas in the air is not available to many higher plants.

While organic agriculture practices result in higher soil organic matter (SOM) contents and, in turn, higher nutrient - and water - supplying potential to crops, transition to organic farming typically involves a lag time of several years in which yields can suffer and input demands increase as rebuilding soil microbial communities compete with crops for nitrogen and other available nutrients (Simmons and Coleman, 2008).

«When the peat is cleared, the natural nitrogen found in the soil is not available for plants, so to ensure that the young oil palms thrive, intensive fertiliser is added during the first three to four years of the plantation.

In other words, with more nitrogen available, plant life might be able to absorb more CO2 than climate scientists have been estimating, which means the planet won't warm as much, despite mankind's pumping CO2 into the atmosphere.

CO2 enhances the nitrogen and phosphorus release in the soil, making it more available for plants.

Limited direct impacts of atmospheric CO2 on nitrogen - fixation have been found in soil biological crusts (Billings et al., 2003), but soil microbial activity beneath shrubs has been observed to increase, thus reducing plant - available nitrogen (Billings et al., 2002).
