  3. Nitrogen and Non-Protein Nitrogen's effects on Agriculture

    en.wikipedia.org/wiki/Nitrogen_and_Non-Protein...

    High levels of ammonia resulting from the breakdown of NPN can disrupt rumen pH balance and microbial activity, leading to conditions such as rumen acidosis and ammonia toxicity. [12] Furthermore, excessive excretion of nitrogen in urine and feces from animals consuming diets high in NPN can contribute to nitrogen pollution in the environment.

  4. Guano - Wikipedia

    en.wikipedia.org/wiki/Guano

    Seabird guano is the fecal excrement from marine birds and has an organic matter content greater than 40%, and is a source of nitrogen (N) and available phosphate (P 2 O 5). [2] Unlike most mammals, birds do not excrete urea , but uric acid , so that the amount of nitrogen per volume is much higher than in other animal excrement.

  5. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    The total nitrogen content depends largely on the soil organic matter content, which in turn depends on texture, climate, vegetation, topography, age and soil management. [40] Soil nitrogen typically decreases by 0.2 to 0.3% for every temperature increase by 10 °C. Usually, grassland soils contain more soil nitrogen than forest soils, because ...

    Faba, an earlier synonym, is from a Latin plant name. [9] [65] [66] 780 genera, scattered worldwide [9] [67] Also known as legumes. Trees, shrubs, vines and herbaceous plants. The roots are generally nitrogen-fixing. Staple foods include soybeans, peanuts, peas and various beans. Some species provide valuable gums, soaps and perfumes. [9] [19 ...

    en.wikipedia.org/wiki/Soil_food_web

    The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Food webs describe the transfer of energy between species in an ecosystem.

    en.wikipedia.org/wiki/Nitrophily

    The word is a contraction of the Greek words νἰτρον (nitron) meaning "saltpetre" and φίλος (philos) meaning "friendly". [1] Nitrophily is traditionally expressed as a score between 1 (not nitrophilous at all) and 10 (extremely nitrophilous) according to the Ellenberg N Index. [2]

  9. Dead zone (ecology) - Wikipedia

    en.wikipedia.org/wiki/Dead_zone_(ecology)

    The Chesapeake Bay experiences seasonal hypoxia due to high nitrogen levels. [32] These nitrogen levels are caused by urbanization, there are multiple factories that pollute the atmosphere with nitrogen, and agriculture, the opposite side of the bay is used for poultry farming, which produces a lot of manure that ends up running off into the ...
