Exchange Properties of an Argiustoll: Effects of Long‐Term Ammonium Nitrate Fertilization Academic Article uri icon


  • Soil acidification can result from the application of high rates of ammonia-based fertilizers, but little information is available concerning the effects of long-term, annual applications at moderate rates. The objective of this research was to determine the effects of such long-term applications of NH4NO3 on exchange properties. Discontinuation of fertilization for 20 yr resulted in a significant, but incomplete, trend of the exchange properties toward values of the unfertilized soils. Thus, the acidification resulting from NH4 application, which occurred at even low application rates, was reversed somewhat after fertilization ceased. -from Authors
