Fig. 1. Soil NH4+ and NO3– concentrations in the 0- to 0.2-m soil layer after application of mineral fertilizer and various types of liquid swine manure to a loam in 2001, 2002, and 2003. Each year, N sources were applied in spring and after the first harvest of hay. Arrows indicate the time of N applications. Vertical bars indicate SD of the means.

Fig. 2. Soil NH4+ and NO3– concentrations in the 0- to 0.2-m soil layer after application of mineral fertilizer and various types of liquid swine manure to a sandy loam in 2001, 2002, and 2003. Each year, N sources were applied in spring and after the first harvest of hay. Arrows indicate the time of N applications. Vertical bars indicate SD of the means.
