Abstract:
Marine algal seaweed species are often regarded as an underutilized bio resource; many have been
used as a source of food, industrial raw materials, and in therapeutic and botanical applications for
centuries. Moreover, seaweed and seaweed-derived products have been widely used as amendments in
crop production systems due to the presence of a number of plant growth-stimulating compounds. A
multifunctional alginate gel beads controlled-release fertilizer has been developed to improve fertilizer
use efficiency and reduce environmental pollution. Sodium alginate based gel beads superabsorbent
used as slow release of Sargassum Wightii sea weed extract was analyzed by inductively coupled
plasma–optical emission spectroscopy. Result showed that the product contained percentage of P
(213.618 nm) shows that 2.10 ppm and K (766.491 nm) shows that 74.52 ppm compared the padina
pavonica sea weed results showed that the product contained percentage of P shows that 2.21 ppm
and K shows that 25.2 ppm. The water evaporation as well as the N, P, K and Micronutrients release
behavior of controlled release in soil was explored. Furthermore, the incorporation of gel beads in
soil could effectively prevent the compaction of soil. Observed the plant study we used different
percentage of sargassum Wightii extract used different wt % ( 1 , 2 , 3 , 4 and 5 ) the result show that 3
wt % used plant height is high compared to other. These studies showed that the product prepared by
a simple route with good slow-release and water-retention properties may be expected to have wide
potential applications in modern agriculture and horticulture.
