(EP1007493-A1)      Production of liquid fertiliser comprises: (a) loading 1 decomposable nutrient containing organic materials in container (22) with vents for nutrients and air outlet (46); (b) submerging the container in a tank of water (14A); (c) applying pressurised air to the air outlet for agitating and aerating organic materials for aerobic decomposition and extraction of nutrients and (d) removing the container from the tank. Also claimed is an apparatus for producing liquid fertiliser which comprises the container, a pressure generating means and 1 tank into which the container can be placed.    Additives are preferably added to water to reduce odour, improve nutrient extraction and improve absorption of nutrients by plants. Additives include microbial activator, biological accelerator or enzyme catalyst. The fertiliser is delivered to plants. The container is submerged in a series of tanks. The air outlet is a perforated pipe at the bottom of the container. The air outlet has a connector and removable cap so that it can be cleaned by pressurised air or water. The container has a hatch for loading and unloading organic material and a lock prevents escape of solid material. The container is supported from a frame over the tank. The container is moved by a conveyor from the loading station to decomposing station to unloading station. The container is pivoted for easy unloading. Unloaded material is composted for use as potting medium.    USE -   The process is used for producing liquid fertiliser from organic material such as manure in a garden or field. The fertiliser is used for producing plant, fruit or vegetable.    ADVANTAGE -   The fertiliser is produced on site, avoiding transport. The fertiliser does not need to be diluted or watered in.
