In the May–June issue of the Journal of Environmental Quality, researchers report on a study using grazed grassland plots from Northern Ireland. Plots received the same rate of inorganic P fertilizer from 1994–1999, different (zero to very high) rates from 2000–2005, and no P fertilizer from 2005–2010. Samples from 1994, 2000, 2005, and 2010 were analyzed in detail to characterize soil P forms and concentrations.
