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 ...
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 ...
Fertilizers with additional macronutrients (S, Ca, Mg) may add more numbers to the N-P-K ratio to indicate the amount. The additional numbers are similarly reported in the oxide mass fraction form. For example, a Polish fertilizer labeled "NPK (Ca,S) 4-12-12 (14-29)" has an equivalent of 14% soluble calcium oxide and 29% total sulfur trioxide. [6]
Another cause of concern is the sheer amount of urea needed to capture the same amount of carbon as eq. iron fertilization. The nitrogen to iron ratio in a typical algae cell is 16:0.0001, meaning that for every iron atom added to the ocean a substantial larger amount of carbon is captured compared to adding one atom of nitrogen.

Other seaweed may be used as fertilizer, compost for landscaping, or to combat beach erosion through burial in beach dunes. [55] Seaweed is under consideration as a potential source of bioethanol. [56] [57] Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care.
[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]
The farmers said they never know if they will have to drop everything to take their animals to Texas A&M for necropsies. James Farmer recorded videos on July 29 to show what the families often ...
Seaweed, such as kelp, also absorbs phosphorus and nitrogen [104] and is thus helpful to remove excessive nutrients from polluted parts of the sea. [105] Some cultivated seaweeds have very high productivity and could absorb large quantities of N, P, CO 2 , producing large amounts of O 2 having an excellent effect on decreasing eutrophication ...
