20 Advantages of Seaweed Fertilizer

1) It promotes additional buds when applied as the plants are beginning to bud.
2) It extends the shelf life of fruits and vegetables if applied 10 days before harvesting
3) It lengthens the life of cut flowers if they are sprayed with Liquid Seaweed a day or two before cutting.
4) Treating seeds or seed pieces with Liquid Seaweed prior to planting will improve seed germination, root growth, and early seedling vigor.
5) Liquid Seaweed also can be used as a rooting solution. Place cuttings in a solution of Liquid Seaweed and water until roots develop, then plant. When planting, water in with Liquid Seaweed solution.
6) Liquid Seaweed applied to pasture crops increases the nutrient uptake, the protein content, and overall quality of the crop.
7) Seaweed organic fertilizers can be used as a soil treatment to grow healthier, stronger, and more disease-resistant plants.
8) A wide range of beneficial effects have been reported from the use of liquid seaweed extracts including increased crop yields, resistance of plants to frost, increased uptake of inorganic constituents from the soil, more resistance to stress conditions and reductions in storage losses of fruit.
9) Promotes vigorous growth and helps deter pests and diseases on fruit, flowers, vegetables, lawns etc.
10) Seaweed has more than 70 minerals, vitamins, and enzymes. 
11) Seaweed fertilizers are especially useful in organic gardening. They contain almost every micro-nutrient in a fully chelated (immediately available) form. They deliver a healthy dose of natural plant hormones. Seaweed is full of carbohydrates, which the plants use as a building block and which large populations of beneficial micro-organisms use as a food source 

12) Alginates, (sponge-like starches found in seaweed), hold water droplets near the plant roots, making moisture available to them without drowning them; they also help enrich the soil by feeding myriad beneficial microorganisms such as bacteria and tiny fungi necessary to composting.
13) Research at major universities has shown that seeds soaked in seaweed extract germinate more rapidly, have larger root mass, stronger plant growth and higher survival rate. Soaking plant roots in seaweed extract reduces transplant shock and speeds root growth.
14) Several university studies have shown that seaweed can produce dramatic results in plants: geraniums produced more flowers per plant; grapes were sweeter; gladiolus corms grew larger; and cucumber yields increased 40 percent and the fruits suffered less often from softening and rotting. Improved yields after seaweed treatments were measured in potatoes, sweet corn, peppers, tomatoes, apples, strawberries, okra, and oranges. Better frost tolerance, increased seed germination, and greater capacity to absorb trace elements were other documented benefits for plants.
15) Seaweed fertilizers have many benefits. They provide natural hormones and many nutrients not found in other forms of fertilizer. Since most plants absorb their nutrients through the leaves, applying this with a foliar method will benefit the plant even more. Foliar simply means placing the fertilizer on the leaf itself. As the plant absorbs the sunlight it needs, it will also be absorbing the nutrients found in the fertilizer.

16) Another major component in liquid seaweed fertilizers are the hormones. The main hormones in seaweed are auxins, gibbelerins, cytokinins and betaines. The roles of these hormones are essential to plant health. Most of these are only required in very small proportions. There are many different auxins and they all have their specific roles. Their main functions are the balanced control of speed of growth. They have both growth stimulating as well as delaying functions. They stimulate root-growth, prevent bud-forming or opening at the wrong times.
17) Seaweed can play an important role in the production of the plant's own auxins, because the enzymes formed with the help of trace elements from the liquid seaweed fertilizer play an important role in the formation of these auxins.
18) Cytokinins are another group of important plant hormones. They initiate and activate basic growth processes. The cytokinins available in liquid seaweed extract stimulate growth with greater vigour, because they mobilise nutrients in the leaves. They also provide protection from marginal frost (to -3 C). Cytokinins also retard the senescence (aging processes) in the plant.
19) Betaines play an essential role in the osmotic processes in plants. They help to increase the water uptake in plants and are extremely helpful in dry conditions. Betaines are particularly helpful to plants under stress.
20) Liquid seaweed fertilizers, (especially the alginates in the seaweed) act as soil conditioners. The alginates react with metals in the soil and form long and cross-linked polymers in the soil. These polymers improve the crumbing in the soil, and swell up when they get wet, and retain moisture for a long period.

How Phosphite is defferent from Phosphate ?

Benefits of Proven Foliar containing  Phosphite--

  • Promotes increase plant health and metabolic functioning

  • Stimulates a plants natural defense mechanisms including 

  • phytoalexin and antioxidant production (3)

  • Directly limits the growth and development of the 

  • oomycetes (Pythium spp., Phytoplora, and Plasmopara) 
Plant Defense Responses
Plants naturally defend against biotic and abiotic pests by triggering specific metabolic responses after pathogen infection, or the onset of adverse environmental conditions such as drought, heat, or salinity. Phosphite has been documented to upregulate these vital metabolic processes necessary for maximum plant health.
Benefits of Proven Foliar phosphate fertilizers containing phosphate are:
  • Phosphorus nutrition is important for turfgrass abiotic stress tolerance and often unavailable (complexed) in the soil.
  • Phosphite stimulates additional plant defense responses
  • Phosphite can be used as one component to an integrated pest management program (see back)
  • Optimum turfgrass health is maintained with adequate primary and secondary macro and micronutrient nutrition
  • Application of phosphate under P deficiency conditions could be detrimental to plants

“PHOSPHONATE USE IN ORGANIC AGRICULTURE”--

PHOSPHONATE is listed as PPP in  n Germany and Austria it is listed as plant
strengthener, and used in organic farming with limitation in certain years. It is not allowed for use
in organic in other countries. In USA it is registered in as PPP (31 brand name products) but
forbidden in organic due to its synthetic origin; the same in Australia (with 8 brand name products
registered)  but not allowed in organic


 German perspective
Used in organic: yes 
Legal framework
2 products containing are available on the market:  "Frutogard" and "Alginure BioSchutz"
(indentical material, two different brand name products). They are listed as 'plant strengtheners', a
cathegory provided in the German Plant Protection Law.  There was a case at the court last year:
The relevant plant protection authority had considered the phosphonates as plant protection
agents and not as a strengthener. But the court decided (more or less on formal reasons, not based
on scientific evaluation) that the products must remain on the Plant Strengthener List.
Formally all "Plant Strengtheners" can be used in organic production in Germany, they must not be
listed in App II of 889/2008 (confirmed in the late 90th by the former EU Commissioner Fischler).


Even if phosphonates are used and researched on since more than 20 years their acceptance in the
organic sector is still debated. About its nature, efficacy and need there is consensual evaluation
but concerning the aspect of residues risk and its mode of action some doubts are expressed:
• phosphonate leave residues on fruit (and soil?). They can be handled by application
strategies but thy still can be a risk;
• the analytical methods to detect phosphonate residues and differentiate their origin are
still developing;
• the mode of action is somehow systemic and as such different from all other products so
far used in organic.
So the difficult decision can only partially be supported by scientific data as the balance between it
agronomic needs/efficacy and the risks in the consumers acceptance as well as in the fulfilment of
organic principles should be evaluated.
For coming years there is a clear need to fill in the knowledge gaps in order to be able to approach
its acceptance in the organic system with the needed scientific background and the requested
participatory approach.

Effects nitrogen and phosphate


Effects

  • Too much nitrogen does not harm plants, but too much phosphate causes leaf yellowing known as leaf chlorosis. Manganese and iron uptake is negatively affected by phosphate


phosphorus effect and Application on plants

Phosphate in its phosphorus form is responsible for energy transfer and carbohydrate metabolism. Phosphorus is important for root development and growth, stem growth, flower and fruit production, seed production and maturation. Deficiencies in phosphate often show up as purplish leaves and stems on trees. In fruit production, increased phosphate increases flower then fruit yield. There are products called super- or triple-phosphates. They are useful in increasing industrial crop yield but are dangerous in home production. The amount of phosphate is triple the other numbers, and unless a soil test says the earth is lacking phosphorus, the use of such products actually poisons the soil.



Phosphorus doesn't move through soil easily. The best time to introduce phosphate to a flowering tree is at planting time, when the root is exposed. An organic source of phosphate, such as bone meal, can be worked into the soil in the planting hole and well-watered. This gives instant life to the plant. Phosphate and most fertilizer should be slow release or introduced when the tree is dormant, to avoid burning the roots. Uptake of phosphates occurs at the root tip, so it is important to water fertilizer in well enough so that it leaches down to roots or digs in to the root area.
