  1. Amend the soil with formulated chemical compounds

    A replicated, controlled study in 1984-1985 on a loam soil in Berkshire, the UK (Thompson et al. 1987) found that adding a nitrification inhibitor to cattle slurry injected into pasture reduced nitrogen losses from 58 kg N/ha (slurry with no inhibitor) to 28 kg N/ha, and to 34 kg N/ha by spreading slurry on the surface. The effect was less pronounced in spring. The slurry treatments – surface application, injection into pasture, and injection with the nitrification inhibitor nitrapyrin – were applied to ryegrass Lolium perenne in December and April at a rate of 80 t/ha. Slurry was poured into ploughed slots in the injection treatments. Each treatment was replicated four times.
