Conversely, total nitrogen concentrations are higher in these plants compared to those growing in open sites with no litterfall.
2.
Hence in benthic sediment gives an indication of the contribution of human waste to the total nitrogen in the sediment.
3.
Furthermore it appeared that total nitrogen oxides level requirements were in place irrespective of whether emissions were flued or not.
4.
These flows mainly stem from corn, which as of 2010 was the major source of total nitrogen loading to the Mississippi River.
5.
In particular, it increases total nitrogen content but reduces some ( possibly harmless ) levels of potentially toxic substances such as soluble oxalate and nitrate.
6.
The added ammonium sulfate's nitrogen boosts the corn gluten's total nitrogen reading and leads the customer into thinking it contains more protein than it actually does, he said.
7.
Total nitrogen ( TN ) concentration in the samples ranged from 50 to 110 mg / l with an average over all samples of 90 mg / l.
8.
Missouri is among four states that each contribute between 6 percent and 9 percent of the total nitrogen flow, said Donald Goolsby, a retired hydrologist of the Geological Survey.
9.
But exposed rock deposits around the world contain as much as 20 percent of the planet's total nitrogen, the researchers calculated, and geology might be a significant contributor in some places.
10.
Increases in the total nitrogen content in vermicompost, an increase in available nitrogen and phosphorus, as well as the increased removal of heavy metals from sludge and soil have been reported.
