Abstract: A process of preparing a microbe digested liquid plant nutrient containing metabolites, amino acids and polypeptides, comprising the steps of partial composting of animal effluent solids; adding the partially composted animal effluent to a vessel containing water and held in suspension; the aqueous dispersion is thoroughly aerated for up to 4 days. Solids and liquids are subsequently removed from the metabolic reactor, separated and used as plant nutrients.

Abstract: A process of preparing a biogenic silica comprising the steps of incinerating a silica bearing organic source at a temperature up to 1200° C. and allowing the incinerated silica organic source to cool; adding the incinerated and cooled silica bearing organic source to an alkaline solution that has either been preheated to a temperature up to about 65° C. or to be heated with the added organic source to a temperature up to about 65° C., the alkaline solution being contained in a vessel and having a pH up to 14; applying heat so that the added organic source and the alkaline solution in the vessel are at a temperature between 100° C. and up to about 300° C. for 1 to 4 hours, thereby forming an aqueous biogenic silica and undissolved impurities derived from the added organic source; and extracting the aqueous biogenic silica from the vessel. The extracted silica can be solidified into a solid form.

Abstract: An apparatus is provided for producing liquid fertilizer from manure. The apparatus includes at least one tank filled with water, a cage having a perforated pipe arranged closed to a bottom floor of the cage and a pump connected to the pipe for delivery of pressured air through the perforations of the pipe. In use, the cage is loaded with fresh manure and then submerged in the tank of water. The pressured air agitates and aerates the manure and thereby causing aerobic decomposition of the manure. Nutrients in the manure are thereby extracted from the manure and mixed with the water to form a liquid fertilizer. A fertigation arrangement can be arranged to deliver the liquid fertilizer from the tank directly to plants.
