Mineral nitrogen in manure is available as ammonium nitrogen and is converted in the soil into nitrate nitrogen. Nitrate does not bind to soil particles and can easily move and spread through the soil. During heavy precipitation, this nitrate nitrogen disappears into deeper layers of the soil, potentially causing it to be lost as food for the crop. Terra-Stabil stabilises the nitrogen and improves the efficiency of slurry. As Terra-Stabil temporarily halts the conversion of ammonium into nitrate by the Nitrosomonas bacterium, nitrate leaching and nitrous oxide emissions are reduced and nitrogen remains present in the soil as ammonium for longer.
