Algae : A new valuable resource for emerging challenges of world agriculture Dr H. DEMAIS Scientific Manager OLMIX S.A Washington – March 22 nd 2013

Increased needs for world production : + 70% in 2050 Source: FAO The Challenge for tomorrow’s agriculture  Cereals : + 1 billion tons  Meat : millions tons  90% of the target has to be achieved by yield improvement & intensification. What does this challenge mean?  Need of efficient soils with good fertility.  Need of healthy plants, with high productivity.  Need of safe feedstuffs, with good nutritional values.  Need of healthy animals, with high production potential. 2  10% « only » of the target can be achieved by surface increase.

 Very diverse group of organisms How can seaweeds contribute to address this challenge? 3  Under-utilized resource  Unexplored activities  Very diverse chemical compositions Earth is 71% covered with ocean water.

Olmix Group : Expert in green blue chemistry Expert in green chemistry for 18 years  Development based on natural alternatives to petrochemical industry through the use of clays and seaweeds How is Olmix successfully addressing that challenge 4 Core Business : Additives for Agriculture  Natural additives (animal and plant nutrition and health)

Amadéite® : the first Olmix revolution for agriculture Biopolymers extracted from green seaweeds Montmorillonite (plentiful and cheap material) +  Water depollution  Mycotoxins adsorption  Biocatalysis A patented organoclay associating clay and green seaweeds Inception of Amadéite® (2004) Na + Ca 2+ Na + Ca 2+ 0,4 nm 2 nm 5

OLMIX : At the heart of the "ULVANS " project for agriculture Algae Cultivation - Harvesting Processing Substitution of chemical phytosanitary products by natural elicitors Substitution of chemical fertilizers and amendments Substitution of fish meal by algal proteins or A.A Feed supplements (Mineral, trace elements vitamins….) Soil and plant nutrition Animal Health Vegetal health Reduction of antibiotic needs : Stress reduction, Immuno modulation, Reduction of antibiotic needs : Stress reduction, Immuno modulation, 9 Animal Nutrition 9

 Seed coating  Solid fertilizers  Ferti-irrigation  Foliar spraying New applications of Seaweed in agronomy A variety of molecules in algal extracts can be potent elicitors of plant defense against pests & diseases Treatments with seaweed extracts have been shown to improve soil quality and plant growth  Oligo and polysaccharides:  Antioxidant polyphenols λ-carrageenan Seaweed in agronomy 10
