We are developing a new seaweed extract, we have performed several test of effectiveness but we would increase the scientific approach. I am a chemistry and I don't know a lot about physiology of the plant, but I would build a simple "grow report" to highlight the effect of our products. We think to check the absorption of the principal macro-nutrient and meso, the quantity of clorophyll, ammino-acids inside the plants and other more agronomic parameter like leaf-area ratio, root length etc. Do you have some advices to give us? we have a simple and old equipment: UV/VIS, HPLC-UV/VIS and tritation system and other classical stuff (balance etc...). Any advice is welcome
Interesting question...
The global seaweed processing industry is estimated to utilise some 10 - 12 million tonnes of seaweeds (frozen weight) annually, sourced from ‘wild harvest’ or cultivated in on-shore and off-shore.. Multicellular marine macroalgae including some members of red (rhodophyta), green (chlorophyta), and brown (phaeophyta) algae. They are widely distributed in the ocean, occurring from the tide level to considerable depths, free-floating (planktonic) or anchored to the substratum (benthic). They lack a specialized vascular system but take up fluids, nutrients, and gases directly from the water. They contain chlorophyll and are photosynthetic, but some also contain other light-absorbing pigments. Many are of economic importance as food, fertilizer, agar, potash, or a source of iodine.
The seaweed extract has been found to contain growth stimulators such as auxins, gibberellins and cytokinin. The extract also comprises growth promoting hormones (IAA and IBA), trace elements (Fe , Cu , Zn , CO Mo , Mn and Ni ), vitamins and amino acids . And also have been reported to stimulate the growth and yield of plants, develop tolerance to environmental stress[6], increase nutrient uptake [7] and enhance antioxidant properties [8]. The use of seaweed extract at the germinating stage showed encouraging results by stimulating the growth of roots and shoots [9]. About 2-10% of seaweed extracts in combination with NPK fertilizer has also been used in some developing countriesto enhance the yield of the crop of the commercially .
