Definitions

  • the present invention relates to a method for treatment of a plant or a fungus with a solution comprising water and a nanofibrillated polysaccharide.
  • controllable watering systems such as drip irrigation
  • the water absorbing additive absorbs excess water and releases it through osmosis to the roots of the plants.
  • the most common used water absorbing additives are water absorbing polymers, such as polyacrylamides which also are called water crystals.
  • the drawbacks with water absorbing polymers are high cost, low biodegradability, toxicity and that it might be difficult to apply the water absorbing polymers evenly to the plants.
  • the main objects of the present invention are to provide an improved method for providing plants or fungi with water.
  • the present invention relates to a method for treating a plant or a fungus which method comprises the steps of; (i) providing a solution comprising water, (ii) adding a nanofibrillated polysaccharide to the solution thereby forming a suspension wherein the concentration of nanofibrillated polysaccharide in the suspension is above 1 ,5% by weight and (iii) subjecting the plant or fungus to said suspension in order to provide the plant or fungus with water.
  • a suspension comprising a nanofibrillated polysaccharide it has been shown that the water consumption of the plant or fungus is reduced. It may be preferred that the nanofibrillated polysaccharide is
  • microfibril I ated cellulose has excellent water binding properties as well as excellent water releasing properties. Furthermore, microfibrillated cellulose is biodegradable which makes it a very environmental friendly material to use.
  • polysaccharide in the suspension is between 1 ,5-30% by weight, preferably between 3-10 % by weight. Concentrations below 1 ,5% by weight did not seem to give the advantage with optimal water releasing properties of the suspension. Furthermore, concentrations above 30% by weight seem to be less beneficial since the suspension almost is in solid state and the water release is very limited.
  • the suspension may be in form of a gel. It may be beneficial to subject the plant or fungus to a gel formed suspension since a gel may be easier to distribute to the plant or fungus and the water loss, i.e. water being flown away from the plant or fungus is strongly reduced. It may be preferred to pour the suspension onto the plant or fungus. In this way it is possible to subject the plant or fungus to the suspension in a very easy way.
  • the suspension is in solid form, preferably in the form of a sheet, composite material, foam or a powder when the plant or fungus is subjected to the suspension.
  • Water is preferably thereafter added in order for the plant or fungus to be able to absorb any water from the suspension. Once water is added to the solid suspension, the nanofibrillated polysaccharide of the suspension is redispersed and absorbs the water which makes it possible for the plant or fungus to absorb the water of the suspension.
  • a benefit with the present invention is that it is also possible to add different additives to the solution and/or to the suspension and due to the characteristic of the suspension, the additive will mostly be retained in the suspension until the plant or fungus can absorb it. Consequently, smaller amounts of additives are removed by waste water etc.
  • a nutrition agent may be added to the solution and/or to the suspension. In this way the plant or fungus is also subjected to nutrition agents at the same time as it absorbs the water.
  • growth hormones may be beneficial to add growth hormones to the solution and/or to the suspension.
  • the growth hormones will thus be absorbed by the plant or fungus once it absorbs the water of the suspension.
  • the plant is a cut flower.
  • a cut flower such as a tulip or rose
  • the lifetime of the cut flowers are strongly improved at the same time as the amount of water needed is reduced.
  • the plant is a plant planted in soil, such as a tree, a bush or crops. By subjecting the roots of a plant planted in soil to the suspension the amount of water need by the plant is reduced.
  • This definition includes bacterial cellulose or nanocellulose spun with either traditional spinning techniques or with electrostatic spinning.
  • the material is preferably a polysaccharide but not limited to solely a polysaccharide.
  • a polysaccharide can be e.g. starch, protein, cellulose derivatives etc.
  • microfibrillated cellulose as defined more in detail below is included in this definition.
  • microfibrillated cellulose is also known as nanocellulose. It is a material typically made from wood cellulose fibers, from both hardwood or softwood fibers. It can also be made from microbial sources, e.g. seaweed fermented fibers, agricultural fibers such as wheat straw pulp, bamboo or other non-wood fiber sources. In microfibrillated cellulose the individual microfibrils have been partly or totally detached from each other.
  • microbial sources e.g. seaweed fermented fibers, agricultural fibers such as wheat straw pulp, bamboo or other non-wood fiber sources.
  • microfibrillated cellulose fibril is normally very thin (e.g. a width of 5-200 nm) and the length is often between 100 nm to 10 pm. However, the microfibrils may also be longer, for example between 10-200 pm, even lengths of 2000 pm can be found due to wide length distribution.
  • Fibers that have been fibrillated and which have microfibrils on the surface and microfibrils that are separated and located in a water phase of a slurry are included in the definition of MFC.
  • cellulose whiskers microcrystalline cellulose (MCC), microcellulose (MC), nanocrystalline cellulose (NCC), nanofibrillated cellulose (NFC) or regenerated cellulose fibers and particles are also included in the definition of MFC.
  • the fibrils may also be polymer coated fibrils, i.e. a modified fibril either chemically or physically, being thus either hydrophilic or hydrophobic.
  • Microfibrillated cellulose can be produced in a number of different ways. It is possible to mechanically treat cellulosic fibers forming microfibrils. The production of nanocellulose or microfibrillated cellulose with bacteria, or fermentation, is another option. It is also possible to produce microfibrils from cellulose by the aid of different chemicals and/or enzymes which will break the interfibrillar bonds, or even dissolve the fibers and fibrills.
  • MFC microfibrillated cellulose
  • WO2007091942 describes production of MFC by the aid of refining in combination with addition of an enzyme.
  • the definition of plant includes all kind of plants with the traits of being multicellular, possessing cellulose, and having the ability to carry out photosynthesis.
  • the definition includes all kind of plants that could be used in horticulture or agriculture.
  • Example of plants are cut flowers, trees, bushes, plant cells, grains, crops etc.
  • a fungus is a member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, Fungi, which is separate from plants, animals, and bacteria.
  • the present invention relates to an improved method for subjecting plants or fungi to water, eventual nutrients or other additives.
  • the plant or fungus is subjected to a suspension that comprises a nanofibrillated polysaccharides in an amount of at least 1 ,5% by weight (of the total weight of the suspension).
  • a nanofibrillated polysaccharide such as microfibrillated cellulose
  • the needed amount of water can be reduced. Due to that microfibrillated cellulose has high amounts of fixed -OH groups at the surface of the fibrils, the MFC has a great absorption capability of polar solvents, e.g. water.
  • MFC can be used as a carrier and/or distributor of liquids, for example to plants. Furthermore, MFC has a very high water binding capacity which reduces the evaporation rate of water and decreased evaporation of water which strongly reduces the amount of water that needs to be added to plants in horticulture and/or agriculture.
  • MFC has the property to form solid remaining materials at low solid concentrations. Due to this property, a continuous hydrostatic pressure is formed within the plant or fungus when the plant or fungus absorbs water from the suspension, compared to if the plant or fungus would absorb liquid water. This continuous hydrostatic pressure will ensure an even but yet restricted water flow to the plant or fungus. A restricted water flow from the suspension also closes the pores/epistles of the plant surface since the plant "believes" it is going into a dry season. In this way the plant decreases the water evaporation from its surface and the water consumption decreases without significantly affecting the growing rate of the plant.
  • polysaccharide in the suspension is between 1 ,5-30% by weight, preferably between 3-10 % by weight of the total weigh of the suspension.
  • Concentrations below 1 ,5% by weight did not seem to give the advantage with the even but yet restricted water flow from the suspension to the plant or fungus, i.e. no continuous hydrostatic pressure was formed. Furthermore, concentrations above 30% by weight seem to be less beneficial since the suspension will be in almost solid state and the water release is very limited.
  • suspension may be preferred to pour the suspension onto the plant or fungus. In this way it is possible to subject the plant or fungus to the suspension in a very easy way. However, it may also be possible to add the suspension to the plant or fungus in any possible way.

  • the nanofibrillated polysaccharide of the suspension is the nanofibrillated polysaccharide of the suspension.
  • the suspension is in solid form when it has a concentration of between 30-100% by weight.
  • the suspension will thus comprise no water or liquid. This may be beneficial when the suspension should be transported to the site where the plants or fungi to be treated are located.
  • Water can either be added by drop irrigation or other water adding methods. It is also possible that water is added by rainfall. Once water is added, the nanofibrillated polysaccharide of the suspension will absorb the water or liquid and thereafter provide the plant or fungus with the water.
  • the amount of water that needs to be added is decided by the dry content or concentration of the suspension. It is however important that the concentration of the suspension is above 1 ,5% by weight in order to get the desired results.
  • Additives may be added to the solution and/or to the suspension. Due to the characteristic of the suspension, the additive will mostly be retained in the suspension until the plant or fungus can absorb it. Consequently, smaller amounts of additives are removed from the plant or fungus by for example waste water flows etc.

  • Possible additives are nutrition agents, such as fertilizers and minerals, pesticides or biocides, or growth hormones. Examples of nutrition agents are fertilizers and minerals, e.g.
