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.
Claims5
A process for producing liquid fertilizer, which comprises the following steps:
- (a) loading one or a mixture of decomposable nutrient-containing organic materials in a container having a plurality of vents in at least one wall thereof for nutrients of the organic material or materials to pass therethrough, and an air supply means positioned therein;
- (b) submerging the container in a tank of water or water-containing liquid;
- (c) applying pressurized air to said air supply means for agitating and aerating the organic material or materials in order to cause aerobic decomposition of the organic material or materials, and to extract a substantial amount of nutrients therefrom;
- and
- (d) removing the container holding solids of substantially decomposed organic material or materials therein from the tank;
- wherein the extracted nutrients pass through the vents and mix together with the water or liquid to form the liquid fertilizer.
