Which nutrient cycle is most affected by the over-use of ammonia fertilizers on commercial farms, as well as by the accumulation of waste on cattle farms and feed lots?

The nitrogen cycle

Explanation:

With these activities, a surplus of fixed nitrogen is produced every year, which increases the levels of nitrogen compounds in the atmosphere. High levels of atmospheric nitrogen, other than N2 are associated with harmful effects, such as the production of acid rain in the form of nitric acid, and greenhouse gases, in the form of nitrous oxide,

In addition, excess fertilizer can reach rivers, lakes and streams through surface runoff. One of the main effects of fertilizer runoff is water eutrophication by reducing the availability of oxygen in the water
