  2. Seaweed fertiliser - Wikipedia

    en.wikipedia.org/wiki/Seaweed_fertiliser

    Seaweed fertilizer can be used as a crude addition to soil as mulch, ... Generally the N:P ratio for seaweeds is 30:1, however, the ratio can differ significantly ...

  3. Labeling of fertilizer - Wikipedia

    en.wikipedia.org/wiki/Labeling_of_fertilizer

    In Australia, macronutrient fertilizers are labeled with an "N-P-K-S" system, which uses elemental mass fractions rather than the standard N-P-K values and includes the amount of sulfur (S) contained in the fertilizer. [5] Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount. The ...

    en.wikipedia.org/wiki/Redfield_ratio

    Redfield discovered the remarkable congruence between the chemistry of the deep ocean and the chemistry of living things such as phytoplankton in the surface ocean. Both have N:P ratios of about 16:1 in terms of atoms. When nutrients are not limiting, the molar elemental ratio C:N:P in most phytoplankton is 106:16:1. Redfield thought it wasn't ...

    [29] [30] The first number represents the percentage of nitrogen in the product; the second number, P 2 O 5; the third, K 2 O. Fertilizers do not actually contain P 2 O 5 or K 2 O, but the system is a conventional shorthand for the amount of the phosphorus (P) or potassium (K) in a fertilizer.

  6. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

  7. Iron fertilization - Wikipedia

    en.wikipedia.org/wiki/Iron_fertilization

    Ocean iron fertilization is an example of a geoengineering technique that involves intentional introduction of iron-rich deposits into oceans, and is aimed to enhance biological productivity of organisms in ocean waters in order to increase carbon dioxide (CO 2) uptake from the atmosphere, possibly resulting in mitigating its global warming effects.

  8. Seaweed - Wikipedia

    en.wikipedia.org/wiki/Seaweed

    Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care. Alginates are used in industrial products such as paper coatings, adhesives, dyes, gels, explosives and in processes such as paper sizing, textile printing, hydro-mulching and drilling.

  9. Marine primary production - Wikipedia

    en.wikipedia.org/wiki/Marine_primary_production

    The seminal synthesis by Geider and La Roche in 2002, [101] as well as the more recent work by Persson et al. in 2010, [102] has shown that C:P and N:P could vary by up to a factor of 20 between nutrient-replete and nutrient-limited cells. These studies have also shown that the C:N ratio can be modestly plastic due to nutrient limitation.
