Abstract
The invention relates to the field of seed germination and growing of plants. A composition comprising a clay, an inert material, optionally a fibrous material, and a fourth component is provided, characterized in that said fourth component comprises a cation selected from the group consisting of Al, Zr and Ti and an anion selected from the group consisting of oxyhydroxide, oxychloride, nitrate, sulfate, chloride, hydroxide and alkoxide, and wherein the concentration of said fourth component ranges from 0.1 to 70 percent by weight (w %), preferably 0.5-25 w %, more preferably 1-10 w %, of the total weight of the clay, the inert material, and optionally the fibrous material, together.
Claims20
A method of enhancing soil comprising adding to the soil a composition comprising 20-50 w % of a clay, 0-70 w % of a fibrous material, 0.1-80 w % of an inert material, and a xerogel, the xerogel containing a gel-forming component being a cation selected from the group consisting of Al, Zr and Ti and an anion selected from the group consisting of oxyhydroxide, oxychloride, nitrate, sulfate, chloride, hydroxide or alkoxide, and wherein concentration of said gel-forming component ranges from 0.1 to 70 percent by weight (w %) of the total weight of the clay, the inert material and optionally the fibrous material, wherein the composition improves seed germination and/or plant growth.
A method for producing pellets, said method comprising preparing a mixture comprising 20-50 w % of a clay, 0-70 w % of a fibrous material, 0.1-80 w % of an inert material, and a gel-forming component being a cation selected from the group consisting of Al, Zr and Ti and an anion selected from the group consisting of oxyhydroxide, oxychloride, nitrate, sulfate, chloride, hydroxide or alkoxide, and wherein concentration of said gel-forming component ranges from 0.1 to 70 percent by weight (w %) of the total weight of the clay and the inert material, adding said mixture to a pelletizer, allowing the gel-forming component in said mixture to form a gel and drying said gel to form a xerogel.
A method to make a potted or pot-less plant with a growth medium, said method comprising putting a composition comprising 20-50 w % of a clay, 0-70 w % of a fibrous material, 0.1-80 w % of an inert material, and a xerogel, the xerogel containing a gel-forming component being a cation selected from the group consisting of Al, Zr and Ti and an anion selected from the group consisting of oxyhydroxide, oxychloride, nitrate, sulfate, chloride, hydroxide or alkoxide, and wherein concentration of said gel-forming component ranges from 0.1 to 70 percent by weight (w %) of the total weight of the clay, the inert material and optionally the fibrous material, in a pot or mould and planting a plant therein.
