  3. 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.

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

    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.

    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 ...

    Elaeagnus, from a Greek plant name [60] [61] [62] 3 genera, mostly in the Northern Hemisphere, Southeast Asia and Queensland, Australia [58] [63] Small trees and shrubs. Several species of Elaeagnus are cultivated as ornamentals. Hippophae rhamnoides has been used in jams and juices for centuries. The roots are generally nitrogen-fixing. [64 ...

  7. Soil fertility - Wikipedia

    en.wikipedia.org/wiki/Soil_fertility

    Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. [3] It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.

    The taxonomic treatment [3] (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) Check-list of North American Birds, the recognized scientific authority on the taxonomy and nomenclature of North America birds.

  9. Soil biodiversity - Wikipedia

    en.wikipedia.org/wiki/Soil_biodiversity

    Extended exposure to high sodium levels results in a decrease in the amount of water retained and able to flow through the soil and a decrease in decomposition rates (this leaves the soil infertile and prohibits any future growth). This issue is prominent in Australia, where 1/3 of the land is affected by high salt levels. [22]
