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 ...
More precisely, the first number ("N value") is the percentage of elemental nitrogen by weight in the fertilizer; that is, the mass fraction of nitrogen times 100. The second number ("P value") is the percentage by weight of phosphorus pentoxide P 2 O 5. The third number ("K value") is the equivalent content of potassium oxide K 2 O. [3]
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.

[citation needed] Seaweed-fertilizer also helps in breaking down clays. [citation needed] Fucus is used by Irish people as a biofertilizer on a large scale. [citation needed] In tropical countries, the bottom mud from dried-up ponds which contain abundant blue-green algae is regularly used as biofertilizer in fields. [citation needed]
