Abstract: The present disclosure relates to an article for enriching soil fertility, a method of manufacturing the same and a method of enriching soil fertility. The article comprising: a plurality of containers, each having a respective fluid-permeable membrane and each containing one or more fertilizers. At least one of permeabilities of the membranes and contents of the one or more fertilizers are selected to control a release of the fertilizers from the containers.

Abstract: A container for controlling release of a soluble fertiliser comprising a first chamber for collecting and holding water, and having an open top and a solid bottom with an orifice that allows water flow freely at a desired rate; a second chamber below the first chamber for receiving water therefrom to dissolve fertiliser held therein, the second chamber having a solid bottom with an orifice through which fertiliser solution can flow in a controlled manner and a perforated plate for holding undissolved fertiliser, the plate is disposed within the chamber and separating the chamber into an upper compartment and a lower compartment; and a third chamber below the second chamber and receiving dissolved fertiliser therefrom, the third chamber having a perforated bottom, the perforations are configured to allow the dissolved fertiliser to pass through while preventing foreign solid particles from entering the container.

Abstract: The present disclosure relates to an article for enriching soil fertility, a method of manufacturing the same and a method of enriching soil fertility. The article comprising a container comprising a fluid-permeable membrane, a fertilizer disposed in the container and a moisture regulator disposed in the container. The moisture regulator is configured to repeatedly absorb moisture from outside the container and release the absorbed moisture into a space within the container based on a moisture gradient existing between the space within the container and outside the container, to control a release of the fertilizer from the container through the membrane. The moisture regulator is further configured to form a base in the space within the container to harbor moisture-sensitive microbes, the microbes being transferable through the membrane based on the moisture gradient.

Abstract: The present invention provides a fertilizing device having a permeable package for fertilizer and a method for slowly releasing fertilizer by placing the fertilizing device in or onto the soil in the vicinity of the plants or the crops. The permeable package is enclosed with a layer for protecting the package and preventing unintended release of fertilizer from the permeable package.
