As shown in previous studies, the litter from the polluted site, which had endured high levels of atmospheric nitrogen oxides and ozone, had
higher nitrogen content than litter from the clean site.
When doing so they said that they had two different kinds, one from Mexican bats (which had
a higher nitrogen content), and the other domestic bat guano, which has a nutrient ratio of 3 -8-1.
While 25 explosives contain
high nitrogen content levels, four types of explosives do not.
The highest nitrogen content, around 2.6 per cent of dry weight, occurs in heather in eastern England, where the average annual fallout of nitrogen is 30 - 40 kilograms per hectare, six times greater than in the relatively unpolluted northwest of Scotland (Environmental Pollution, vol 88, p 193).
Not exact matches
Meat industry wastewater may also have a
high content of
nitrogen (from blood) and phosphorus, in addition to pathogenic and non-pathogenic viruses and bacteria, and parasite eggs (not to mention disinfectants and detergents may enter the wastewater stream during facility - cleaning activities, including acid, alkaline, liquid paraffin and neutral compounds)
First, the researchers observed that the visited trees had a
higher content of
nitrogen than the trees to which the ants did not have access.
The team tested a wide variety of sources of biomass — leaves, stems, flowers, seeds, and legumes — with particular interest in those with
high protein
content because the amino acids that make up proteins are a rich source of
nitrogen.
On the other hand, at
high (and very low) BPEI
content, the
nitrogen atoms are located primarily at the edge sites of the aromatic domains.
Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient
content (e.g., through input of material exposed on shelves or
nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a
higher carbon export per unit of limiting nutrient exported.
The significantly
higher protein
content was modestly offset by slightly more calories in the control phase, which reduces the amount of protein required to maintain
nitrogen balance.
If the soil is poor, the leaves may experience
nitrogen deficiency, but if it is too rich, the fruit will become sensitive to alkaline conditions and have
high sodium
content.
Not only do they cost more, they are also
high on
nitrogen content.
Wheat for example is often grown with
high nitrogen fertiliser in poorer soils because it is paid for by the protein
content.
In this popular PADI course you'll learn why diving with air that has
higher oxygen and lower
nitrogen content gives you more bottom time, along with enriched air equipment considerations.
