The product is a dry, free flowing, powdery-to-granular mixture of cross-linked hydroabsorbent polymers, growth precursors and volcanic rock enriched with soluble, slow release and synthetic nitrogen fertilisers. The product has an absorption capacity of a minimum of 4500 g H2O/100 g in distilled water using Method of Analysis CEN EN 13041 and more than 95% of the water contained in the polymers is plant available. The soil conditioning technology has to be mixed homogeneously into the root zone or growing medium. [Diagram showing soil conditioning technology being mixed into the root zone] ## BENEFITS * HEALTHIER PLANTS & INCREASED YIELDS * INCREASED SURVIVAL RATE * INCREASED WATER RETENTION CAPACITY * WATER SAVINGS OF UP TO 50% * STRONGER & DEEPER ROOT DEVELOPMENT * FASTER & BETTER PLANT ESTABLISHMENT * HIGHER RESISTANCE TO DROUGHT STRESS AND DISEASES * BETTER USE OF FERTILISERS * ENABLES PLANT GROWTH IN DEGRADED, SALINE OR OTHERWISE MARGINAL SOILS ## APPLICATIONS Tree & shrub planting Flower and shrub beds, roof gardens, lawns, etc. Window boxes, hanging baskets and containers Horticulture Agriculture ## WHEN TO APPLY? When planting or just before seeding. ## APPLICATION FREQUENCY? Just once. ## MACHINERY REQUIRED FOR APPLICATION? For lawns and large areas of land: Fertiliser spreader (preferably drop type) & rotary hoe. ## COMPOSITION * Mixture of cross-linked hydroabsorbent polymers ........ 39.50% * Fertilisers ...................................................................... 10.50% * N total ............................................... 4.5% * P2O5 soluble in mineral acid .................. 1% * K2O soluble in water .......................... 5.5% * Micronutrients: B, Cu, Fe, Mn, Mo, Zn * Growth precursors............................................................ 0.25% * Volcanic rock.................................................................. 49.75% ## TECHNICAL CHARACTERISTICS * Bulk Density..................................................................~ 800 g /l * Dry matter..........................................................................~ 96% * pH (1 g /l H2O)........................................................................ ~ 7 * Absorption capacity in distilled water (Method of Analysis CEN EN 13041)........ .minimum 4500 g H2O/100 g * Absorption capacity in solution of 2 g/l Ca(NO3)2 (Method of Analysis CEN EN 13041)..........minimum 1500 g H2O/100 g * Dry granular mixture free of micro-organisms * Certified non-toxic * Particle size............................................ 0.63 mm – 4 mm (>85%) * Lifespan........................................................................... 8 years *** # UNIVERSAL Leading soil conditioning technology ## APPLICATION RATES & METHODS ### AGRICULTURE Application per plant hole – see Tree & shrub planting ### HORTICULTURE Containerised application – see Baskets, containers, troughs etc. ### TREE* & SHRUB PLANTING 1-2 kg per m3 growing medium or soil taken from plant hole or 1-2 grams per litre soil [Diagram showing 6 steps for tree and shrub planting] 1. Dig plant hole at least 2x the diameter of the root ball, container or spread of roots in the shape of a cube. Keep small amount of soil from the hole apart from the rest. 2. Add TerraCottem® Universal (TCU) to soil taken from the hole at recommended rate and mix well. 3. Fill partially with TCU-soil mixture. Place tree in hole. 4. Fill partially with TCU-soil mixture not higher than the top of the root ball. 5. Apply the soil set apart earlier as a mulch layer, creating a concave shape to trap available water. 6. Water thoroughly. ### FLOWER & SHRUB BEDS, LAWNS, ETC. 100-200 grams per m2 or 500-1000 grams per m3 growing medium mixed off-site [Diagram showing 7 steps for flower and shrub beds, lawns, etc.] 1. Apply TerraCottem® Universal (TCU) to surface at recommended rate with a fertiliser spreader or mix off-site with growing medium and apply this to surface. 2. For small areas (e.g. a couple of dozen square metres/yards) and slopes apply TCU manually at recommended rate. 3. On the same day, incorporate TCU into the root zone to a depth of 20 cm/8 inches with a rotary hoe or similar, across the length and width of the area. 4. For slopes, use a hoe to incorporate the product into the soil at a depth of 20 cm/8 in. 5. Prepare the soil for planting or seeding. 6. Plant or seed & water thoroughly. 7. Water thoroughly. ### ROOF GARDENS, BASKETS, CONTAINERS, TROUGHS, ETC. 5 kg per m3 growing medium or 5 grams per litre growing medium 1. Mix TerraCottem® Universal (TCU) completely with substrate at recommended rate. 2. Fill bottom of container with TCU-soil mixture. 3. Place plant in container and fill with this TCU-soil mixture. 4. Water thoroughly. | Plant size | Planthole size | Planthole volume in litres of soil | TC Universal rate | | :--- | :--- | :--- | :--- | | Tubestock | 10 x 10 x 30 cm | 3 | 10 g | | 100mm | 20 x 20 x 30 cm | 12 | 20 g | | 140-150mm | 30 x 30 x 30 cm | 27 | 40 g | | 200mm | 40 x 40 x 40 cm | 66 | 100 g | | 300mm | 60 x 60 x 60 cm | 216 | 300 g | | 25 LT | 63 x 63 x 63 cm | 250 | 375 g | | 45-50 LT | 80 x 80 x 80 cm | 512 | 750 g | | 75 LT | 90 x 90 x 90 cm | 729 | 1.125 kg | | 100 LT | 1 x 1 x 1 m | 1,000 | 1.5 kg | *\*fruit trees, evergreens & deciduous trees* The above-mentioned rates are applicable in the majority of cases.
