Sea Weeds – Its usefulness for income

generation to the coastal people


2/57

With 76 percent of the world’s fish stocks fully

exploited or overexploited, and many species

severely depleted, many policymakers andscientists now agree that we must adopt a

radical new approach to managing the seas: one

that is precautionary in nature and has the

protection of the whole marine ecosystem as its

primary objective !his "ecosystem approach#

is vital if we are to ensure the health of our

oceans for future generations

Why $eaweeds%

Seaweeds have several uses, gaining

momentum as a new experimental

system for biological research and is

a part of integrated aquaculture

systems

&ecause 344*310 contains a mix of fish emulsion

and seaweed extract, it contains everything a plantneeds for good health and vigor 3s a plant itself,

seaweed contains 3'' of the trace elements that a

plant needs in 53+!' the correct balance 1oother fertili2er type has that benefit /n addition, these

trace elements are already in chelated form so that

they can be absorbed by the plant more easily 8anyother fertili2ers do not have this benefit, and therefore

are wasted to a certain extent

$eaweed would be a great compost material, added like leaves

8aybe layer soil, seaweed, newspaper and kitchen scraps /

sometimes catch rain water in big plastic tubs 3lgae grows in

it and / dump it on my compost

Fertilizer

!he most advantage of fermented seaweed extractfertili2er is the multiformity of the end product, which

can be completely easily absorbed by plants, especially

the natural bioactive substances in seaweed are

furthest maintained in the end product

-ermented $eaweed fertili2er 9ower 9 is natural

organic foliar fertili2er produced by twophase

fermentation


29/57

'i;uid seaweed fertili2er 9ower 9 contains rich various

nutrients of alginic acids, auxins, cytokinin and gibberellins etc?,

vitamin, nucleotides, humic acids and counterstresses genes, as

well as macro elements and microelements >1, , @, +a, 8g, $,

-e, 8n, +u, An, 8o, & etc?, which can be easily absorbed byplants, and bioactive substances that stimulate plant growth

articularly, heavy metal content in 9ower 9 is allowed by

legislation in any country

!herefore, $eaweed fertili2er 9ower 9 is a perfect fertili2er

converging nutrients, bioactive substances and counterstresses

genes, which are from completely nature seaweed extracts
