Effect of Nitrogen Rates and Mowing Heights on ... UFDC Home
High NO3N leaching peaks were observed after the fertilization events, which supports the potential for leaching of quick release fertilizer s such as urea if applied at higher N rates. Higher N rates and higher mowing heights produced better quality turfgrass and increased shoot growth but do not compensate enough to reduce NO3N leaching.

Allegro MicroSystems Soldering Methods for Allegro ...
During assembly processes, the high processing temperatures can accelerate leaching, but more significant are the longterm effects. Leaching of various contaminates by water can occur over time, even in overmolded applications. This can lead to the formation of corrosive compounds after the end product has been sent to the field.

The leaching of fly ash is a time dependent phenomenon. The initial leaching of the fly ash can be characterized by the surface hydrolysis and the dissolution of reactive phases formed under high temperature combustion. A close examination of the leaching studies show a rapid early dissolution followed by a later, slower release of the elements.
