True or False: The nitrogen in manure is equally comprised of ammonium N and organic N.

The assertion that the nitrogen in manure is equally comprised of ammonium nitrogen and organic nitrogen is not accurate. Manure typically contains nitrogen in different forms, including ammonium N, organic N, and nitrate N, but the proportions of these forms can vary significantly based on several factors, including the type of manure, the management practices employed, and the conditions under which the manure is produced and applied.

In most cases, manure is predominantly composed of organic nitrogen, which requires microbial activity to convert it into forms available for plant uptake. Ammonium nitrogen, on the other hand, is readily available for plants and is often present in smaller amounts than organic nitrogen. Therefore, the statement does not hold true in a generalized context.

Overall, stating that the nitrogen in manure is equally comprised of ammonium N and organic N doesn't reflect the typical chemical makeup of manure and overlooks the complexities and variations present in various manure types.
