1 Natural and universal foliar fertilizer Ekorast d.o.o. Ljubljana, february 2012

2 About Extragreen Natural and universal foliar fertilizer from the sedimentary rock of marine origin Strengthens the plant via the intermediary of the leaves, increases photosynthesis, reduces the length of growth periods, increases the quantity and quality of products, increases the maximum length for storage of products in warehouses, etc. Advantages of using Extragreen –Natural ingredients –Reduces water consumption –Excellent performance in drought periods –Reduces the need for other protective means –No damage for the plant, the soil, or for consumers –Environmentally friendly The fertilizer enables and is suitable for eco production

3 Cooperation of Slovenian, Croatian and other foreign scientists and researchers in the field of using and processing minerals for the use in ecological agriculture New micro-crushing procedure for breaking minerals without the use of electro-chemical techniques which could induce the alteration of natural ingredients Setting up the company Ekorast Ltd., cooperation with Kočevje business incubator Various experiments and studies on different cultures in Slovenia and abroad Development of new products : Extramin, Extrazeo Extragreen: research & development, innovations

4 Extragreen production process In the tribo-mecanical activator the mineral particles are subjected to an average of 3000 collisions per second, at speeds of up to three times the speed of sound. The particles undergo dynamical clashes as a result of which they are broken down into small particles (millionth of a millimeter). The process induceses a broken and irregular surface on each particle, which sets up a large active area.

5 Production process & innovation The innovation is in the size and the reactivity of the particles: Extragreen is activated calcite which represents the smallest particle size used in agriculture. The particles of 0.1µ to 2µ are 10 to 100 times smaller than the finest of calcareous enriching agents, meaning an active surface which is 1000 to one million times greater. The active surface is the contact surface between the particles and the natural environment: it is on this surface that the biological activity of a mineral depends. The particles of Extragreen are going to liberate a much more significant proportion of calcium and of carbon dioxide which the plant can use. The tribo-mechanical activation does not simply play on the size of particles but also on their properties: a fragmented and irregular surface as well as a re-distribution of the electrons at the surface of the mineral. The reactivity of the particles resulting from the tribo-mecanical activation interests numerous researchers in various different scientific fields where studies are being conducted (solid-state physics, medicine, agronomy) in order to understand the process better.

6 Ingredients: mineral calcite, dolomite, zeolite, Form: micronised dust Size of particles: 0,0001 – 0,002mm Technology: micronisation and activation through a dynamic process of micro-crushing induced by great speed, friction and interaction between particles. Patented process. Solubility: 3 – 4% chemically soluble, over 90% colloidal Applying: 0,3%. To be sprayed on green parts of the plant Dosage: 1-1,5 kg/ha for each spraying Frequency of application: every 10 to 14 days in a single vegetation period Extragreen: data sheet

8 Using Extragreen Dosage: 0.5% Garden: approx. one teaspoon to one liter of water, applied with a horticultural spraying device Agriculture: 1kg for 200 l water Frequency: every 10 to 14 days from the appearance of three leaves on the plant until harvest time. Increase the number of sprayings in the case of plants which are weak or affected by disease. Ideally the atmosphere should be neither dry nor windy for optimum penetration of calcite (spray preferably in the evening or early morning)

9 Extragreen application process overview When Extragreen is sprayed onto the foliage the activated particles can: 1.either break up on the surface of the leaf, thus permitting the absorption of calcium and carbon 2.or enter the interior of the leaf directly by crossing the ostiole Image: The particles of CaCO ₃ (0.1micron) cross the ostiole (on average 10 microns) leaf surface CaO CO 2 (Cu, Zn, MgO) exterior interior stoma sub-stoma chamber ostiole

10 Extragreen application process overview The “pores” of the leaf, the so-called ostioles, measure an average of 10µ. Due to their minute size, the Extragreen particles pass through the ostiole. The development of plants is restricted by an archaic mechanism known as photorespiration: when the inner center of the leaf becomes low in CO2, the Rubisco enzyme determines the oxygen and thus triggers off a biological process which consumes a high level of energy and water, reducing photosynthesis by 20 to 30%. CO 2 Rubisco Extragreen particles progressively break up thus releasing CO2 and calcium: the Rubisco enzyme then determines the CO2 and orientates the plant’s activity towards photosynthesis, in this way strengthening the development of the leaves and fruits In the leaf it is the Rubisco enzyme which triggers off the growth.

11 Effects of composive elements of Extragreen CO₂ EFFECTSCALCIUM EFFECTS Reduction in water requirements:  The CO 2 -saturated atmosphere inside the leaf triggers off the partial closing of the stomata, which induces reduction of evaporation and water loss Structural effect:  Formation of the plant cell wall  Responsible for the integrity of the cellular membranes Increase in photosynthesis (30%):  Orientation of the Rubisco enzyme towards photosynthesis which induces decrease in photorespiration (the photosynthetic and photorespirative activities are two competitive mechanisms, controlled by the Rubisco enzyme) Functional effect:  Extragreen permits a supply of calcium which is directly available inside the leaf. Now the calcium, with little scope for movement, is an essential element.  Transmitter of the immune response  Constituent of the ATPase: enzyme for the creation of energy necessary for the production of sugars in the plant.

12 strengthening of the plant more rapid growth thicker leaves with better pigmentation improved resistance to diseases Effects on plants

13 Reduced water requirement Greatly reduced water requirement (up to -70%) Improved resistance to hydric stress (lack of water) Pepper plant treated with Extragreen. The impressive density of the peppers as well as the small dimensions of the root system are clearly visible. The root systems has not needed to develop further due to better utilization of water by the treated plant.

14 Studies and experiments with Extragreen Slovenia: Hops Grapevine Potatoes Green salad Abroad: Potatoes (Croatia, Turkey, France) Green salad (Turkey, Germany) Strawberries (Italy, France) Apples (Croatia) Beans (Germany, Italy) Carrots (Germany) Corn (Germany) Grapevine (France, Croatia) Roses (Australia) Tea (China) Tomatoes (Croatia) Peppers (Italy, Croatia) Olives (Croatia) Melons (Italy) Soy (Croatia)

15 Potatoes ALSACE, FRANCE 2004 The application of Extragreen on the potato gives excellent results: during trials in 2004, yields increased by 30%. For most of the varieties: 100% of marketable potatoes. The strengthening of the leaves also has an effect on the appetite, significantly reducing action by Colorado beetles. Trial on the varieties: Mona-Lisa, Samba, Désirée, Charlotte, Emeraude, Junior, Délicatesse

16 Melons MODENA, ITALY 2004 Comparison between melons treated with Extragreen and control melons. These observations indicate that Extragreen has a very strong action on the fructose and glucose levels, showing a high potential effect on the organoleptic qualities. Melons not treated with Extragreen Melons treated with Extragreen Unit of measure -ment Results Dry residue g/100g+5 % Fructose g/100g+45 % Glucose g/100g+45 % Saccharose g/100g- 0.6 %

17 Strawberries Haut-Rhin, Colmar, FRANCE 2004 Increase in yield: +30% Trial carried out on Gariguette, Mara, Florence, Majoral, Honeoye, Darselect varieties Better firmness and improved storage qualities (as testified by the producer “no strawberries were returned this year for the first time ever”) Perfect state of health of the plants

18 Grapevines SADEF laboratory, 2004 The application of Extragreen alters the structure of the leaf surface, causing a self-moisturizing effect: Vine not treated with Extragreen Vine treated with Extragreen On this untreated vine spraying of water results in the spreading of little drops of water over the leaf: The contact surface between the water and the leaf is thus relatively weak. On a vine which has been treated, water does not form in drops but rather is distributed evenly over the surface of the leaf: this self- moisturizing effect perhaps helps to explain the action of Extragreen on the reduction in water requirements.

19 Prevention of contamination %, number of plants contaminated by powdery mildew Plants unharmed at the beginning, treated with Extragreen (pink) and untreated (blue), and placed near the plants affected by powdery mildew According to these observations, the application of Extragreen would have a preventative effect, reducing the contamination of healthy plants by powdery mildew.
