The researchers evaluated the effects of hot water treatments on symptomless lucky bamboo planting material and tested fungicides for the control of Colletotrichum in asymptomatic
The most important finding of our study was that the hot water treatments tested were not promising for the control of C. dracaenophilum latently present in lucky bamboo as plants become more susceptible at higher temperatures the researchers said.
Thus water stress may trigger the induction of symptoms the authors said. Remarkably analyses showed that 25%to 43%of noninoculated lucky bamboo stalks included in the study contained the latent presence of Colletotrichum dracaenophilum.
The authors determined that traditional hot water treatments such as those tested in the study were not promising for controlling the latent fungus

or water and it's through erosion that soil is lost. If it is an organic soil we also lose it by subsidence
Since the soil is the source of water and nutrients for plants as well as a bioreactor to purify
and filter water it is crucial to our quality of life. Soil erosion occurs when the soil is protected not from the elements.
Raindrops can break apart the soil making it easier to move it by wind and water.
The water's ability to enter the soil is reduced and more water now can flow over the top of the soil.
Unfortunately water is powerful and can carry away soil particles if it flows overland. Since water flows downhill that's where the soil goes once water erosion begins.
Where does the soil end up? It might end up at the bottom of a hill or it might end up in a river
or stream or in the ocean or it might end up in a reservoir. If the soil ends up in reservoir it limits the space for water
and has to be removed by a very expensive process called dredging. If the soil dries out

In addition the researchers watered and fertilized trees in accordance with local practices or gave them only little water or no fertilizer.

This may best be explained by way of reference to local resource-competition for water among plants
This is where intense localised resource-competition for water exists among existing vegetation. If competition becomes too strong and available soil moisture resources too scarce this could lead to the emergence of bare patches with a lush peripheral grass ring formation.

The analysis found that 99.6 percent of the water in the network passes through filtering sediment along the banks of creeks streams and rivers.

and Brian Kiel a Ph d. candidate in geology at the university's Jackson School of Geosciences provides valuable information to those who manage water quality efforts including the tracking of nitrogen fertilizers used to grow crops in the Midwest in the Mississippi river
and the rate at which the water flows through the sediment. The sediment operates as a chemical filter in that microbes in the sand gravel

One compound nitrate is a major component of inorganic fertilizers that has helped make the area encompassed by the Mississippi river network the biggest producer of corn soybeans wheat cattle
and hogs in the United states. But too much nitrogen robs water of oxygen resulting in algal blooms and dead zones.
While the biggest source of nitrates in the Mississippi river network are industrial fertilizers nitrates also come from animal manure urban areas wastewater treatment
despite an image of water flowing freely downstream nearly each drop gets caught up within the bank at one time or another.
But not much of the water--only 24 percent--lingers long enough for nitrate to be extracted chemically.
The residence times when water entered the hyporheic zones ranged from less than an hour in the river system's headwaters to more than a month in larger meandering channels.
A previous unrelated study of hyporheic zones found that a residence time of about seven hours is required to extract nitrogen from the water.
