  1. Cow urine is a source of nitrous oxide emissions (N2O), a gas that is 300 times more powerful than carbon dioxide.
  2. Most times, when cow urine is used in degraded pastures, which are also seen in vast tracts of land in India, N2O emissions are tripled.
  3. That cattle and livestock are a significant source of methane, a greenhouse gas, and therefore a contributor to global warming is well-known. However, the role of cow urine is less understood.
  4. Dung and urine are commonly mixed together for manure in Indian fields. Since, India also hosts the world’s largest livestock population, as well as significant tracts of degraded land, the findings may have a bearing on nitrogen emissions from Indian fields.
  5. A 2012 satellite study by the Indian Space Research Organization (ISRO) said that about 30% of India’s geographical area (or about 96.4 million hectares) is degraded.
  6. Degraded grasslands emitted more N2O than healthy pastures because the vegetation in the latter took up some of the reactive nitrogen compounds and only the leftovers were emitted.
