Of the DTWs, an important observation was that the occurrence of groundwater nitrate contamination was directly related to well tube material with different joint pathways. Nitrate in seamless-tube wells was lower statistically significantly than those in multiple-section tube wells (p < .001). ...

Ammonia readily dissolves in water with the liberation of heat. NH3 + H2O ⇌ NH4+ + OH− These aqueous solutions of ammonia are basic and are sometimes called solutions of ammonium hydroxide (NH4OH). The equilibrium, however, is such that a 1.0-molar solution of NH3 provides only 4.2 mi...

Water boils at 212 degrees Fahrenheit, and dilute (2 percent) ammonia solutions will boil within a few degrees of this temperature. Concentrated (10 percent) ammonia solutions, however, have boiling points of about 145 degrees Fahrenheit. In general, the higher the ammonia content, the lower the...
Increased irrigation water salinity was associated with significant increases (P < 0.001) in the EC1:5, SWC, and NH4-N contents of soils, but significant decreases (P < 0.001) in soil pH, SOC, TN, and NO3-N contents (Table1). Soil NO3-N content ranged from 31.96 to 46.19...

The municipal tap water utilized during the testing was found to have a total chlorine content of 2.5 ppm and a combined chlorine content of 2.0 ppm. The experiment indicated that the #1 SFB solution protected the test fish, not only from death, but also from the stressful effects of the...
