It has become well known that growing plants in soil for harvest depletes soil nutrient reserves, and if not replenished the soil becomes lifeless. For greenhouse growers the problem starts at day one, because Soiless mixtures contain no nutrient value for plants to sustain life. Silicon is readily absorbed by terrestrial plants, which contain appreciable concentrations. Silicon is the second most abundant element in plants and with out it they can not survive. However, this fact is commonly overlooked by growers. A common source of silicon is clay. Clay particles contained in the soil largely determine a soils suitability for cultivation. The most frequently found silicate clays are aluminum silicate, magnesium silicate, calcium silicate and potassium silicate. Silicates are a decisive factor in the healthy development of plants, not only for the silicic acid content, but also for trace elements, pH buffering, and enhancement of the microbial population in the growing medium.
Clay surfaces absorb large amounts of plant nutrients without any appreciable change in the osmotic concentration of the growing medium or fluctuation of pH. The bond which holds clay together is very weak. The potential bonding with water is stronger than the bond with the clay, resulting in the clay literally falling apart when exposed to water. This falling apart creates a slow release of silicic acid, which is the property of PyroClay.
A light dusting (0.5 grams per litre of media) of PyroClay over the media after seeding. For optimum results, water in 0.5 grams per litre of PyroClay with NutriBoost (plant enzyme rooting initiator) amended solution.
In drain to waste, or drip systems, the best results are obtained with the placement of PyroClay on the top of the transplant block directly under the dripper. Sprinkle 1-2 grams (1-2 Tsp) of PyroClay on top of the media after transplant.
Recycling system Including NFT:
For recycling water culture, including NFT, there is the consideration of the additional nutrient elements, which are added when PyroClay is dissolved in the reservoir. To maintain silicon levels of 1400 ppm add 2.5 grams per litre of reservoir volume bi-weekly.
Containers & Hanging Baskets; Mix into media at the same rate 5 grams per litre.
Golf Course Greens and Fairways:
Mix PyroClay with the top 6 inches of soil/sand at a rate of 22 Kg per ton of media at initial construction. Top dress with 45 Kg per acre with PyroClay each spring and fall.
Top dress with 135 kilograms of PyroClay per acre after harvest in the fall or between harvest on multiple cropping.
Add 2 grams of PyroClay to each 100 liters of water storage and ensure maximum aeration. Repeat each time reservoir is refilled.
Add 25 grams of PyroClay to every 100 liters (25 gallons) of water. Agitate at 3000 rpm for 20 minutes. Apply through pressure or overhead misting.
Harvest & Pruning Stress:
Cover all pruning and harvest wounds with PyroClay , or mix with water and apply as a foliar spray. Apply the PyroClay at the end of the day at a recommended rate of 10 lbs. per acre of 10 kilograms per hectare.
Crown & Stem Stress:
Add Slowly, mixing 2 kilograms of PyroClay with water to make a thick paste. Apply a thick coat to all visible lesions. Place 15 grams of PyroClay around the root crown of all plants in the affected growing area.
Top Dress for acreage:
Top dress with 180 kilograms per acre of PyroClay as soon as any fungus is noticed.
