The effects of soil acidification (pH values from 6.5 to 3.8), and subsequent leaching, on levels of extractable nutrients in a soil were studied in a laboratory experiment. Below pH 5.5, ...

Leaching is the process in which extra water is added to a field and allowed to soak through the soil and drain away underground. A common method of leaching is to pond the water in basins over ...

Laboratories performing environmental trace analysis of toxicologically and environmentally relevant elements have an ever increasing demand for robust and easy-to-use acid digestion or leaching of ...

A promising new form of ammonium phosphate fertilizer has been field-tested by University of Illinois Urbana-Champaign researchers. The fertilizer, struvite, offers a triple win for sustainability and ...
