Mean mineral composition (g kg⁻¹) and pH of soils (0–7.5 cm cores) from plots of hybrid ryegrass in the autumn and following spring after application of inorganic N or slurry from lambs offered different silages.

Analysis of variance was used to assess differences between composition of soils for all treatments (T), sampling time (S) and the interaction between treatment and sampling time (T.S). Effects were apportioned using a Student Newman Keuls test (different superscripts following mean indicating significant differences (P<0.05) between treatments). N = 4.
