Abstract
Official abstract text for this publication.
A peat moss composition having improved water holding capacity, hydrophilicity, and/or anti-leaching properties comprising one or more polysaccharides, for example guars and/or guar derivatives, is disclosed. A method of preparing the peat moss composition and a method of using it are also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition consisting of peat moss and one or more polysaccharide selected from the group of hydroxypropyl guar (HP guar), cationic hydrophobically modified hydroxypropyl guar (cationic HMHP guar), and hydrophobically modified cationic guar (HM cationic guar). 2. The composition of claim 1 wherein the one or moer polysaccharides comprises about 100 to 30,000 parts per weight per million (PPM) parts by weight peat moss in the composition. 3. The composition of claim 1 wherein the one or more polysaccharides comprises about 500 to 10,000 parts per weight per million (PPM) parts by weight peat moss in the composition. 4. A method of improving the water holding capacity, resistance to leaching of nutrients and/or pesticides from, and/or improving the hydrophilicity of peat moss consisting of incorporating in the peat moss one or more polysacharides selected from the group consisting of hydroxypropyl guar (HP guar), cationic hydrophobically modified hydroxypropyl guar (cationic HMHP guar), and hydrophobically modified cationic guar (HM cationic guar); spraying or mixing a powder, solution, suspension, and/or premix of a controlled concentration of the one or more polysaccharides on or in the peat moss substrate. 5. A method of plant cultivation comprising planting a plant in a peat moss substrate consisting of one or more guars derivatives selected from the group consisting of hydroxypropyl guar (HP guar), cationic hydrophobically modified hydroxypropyl guar (cationic HMHP guar), and hydrophobically modified cationic guar (HM cationic guar) and peat moss.
