Definitions

  • This invention relates to a soil additive composition, and uses thereof.
  • Agricultural fertilizers comprise well-known macronutrients such as nitrogen, phosphorus and/or potassium, as well as sulphur in many cases.
  • Nitrogen, phosphorus and potassium are typically provided as water soluble compounds such as ammonium nitrate, ammonium phosphate, urea, and potash.
  • a water soluble sulphate fertilizer such as ammonium sulphate is possible, but uptake suffers from immediate dissolution, resulting in uncontrolled release and leaching, thereby leading to poor returns on farm input investment.
  • Particulate elemental sulphur may be used in fertilizer applications, but elemental sulphur is very slow in reaching the roots of plants. Sulphur in its elemental form is insoluble in water and hence cannot be absorbed by the roots of plants. It is converted by bacterial action into water soluble sulphate which is subsequently readily absorbed by plant roots.
  • Micronutrients may also be applied in a fertilizer, and may include essential plant nutrient elements such as boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), and chlorine (Cl).
  • essential plant nutrient elements such as boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), and chlorine (Cl).
  • Soil amendment products are known which are used to improve the physical properties of soil, such as water retention, permeability, water infiltration, aeration and structure. Many soil amendment products also include fertilizer macro- and micronutrients as well.
  • the invention relates to a soil additive product which may promote beneficial microorganisms in the soil, act as a fertilizer catalyst, reducing loss and soil tie- up of applied fertilizer, and/or may have other beneficial effects.
  • a composition described herein may enhance the production of crops suffering stress derived from cold or hot temperatures, unbalanced soil conditions, moisture availability, and disease.
  • compositions comprise essential nutrients which are important to plants, particularly emerging plants, and may enhance root growth and nutrient uptake.
  • the invention comprises a composition, comprising
  • a water soluble extract of algae preferably a brown algae of the class Phaeophyceae, more preferably of the family Fucaceae, and most preferably of the genus
  • composition is preferably water-soluble and/or may be in liquid form.
  • the invention comprise a method of preventing or ameliorating fungal crop diseases, such as clubroot, comprising the step of applying a soil additive composition of the present invention to soil either before or after seeding.

  • Lignin is a class of complex organic polymers that form key structural materials in the support tissues of vascular plants and some algae. It is not water-soluble but may be made so by derivitization, such as by sulphonation or carboxylation.
  • a "lignin derivative" is a material which comprises lignin that has been chemically modified to vary or improve a physical property of lignin. Therefore, in some embodiments, the lignin derivative is water soluble, and may comprise a sulphonated lignin or a carboxylated lignin. Preferred sulphonated lignin may include ammonium lignosulphonate. In other embodiments, the lignin or lignin derivative may comprise insoluble, finely divided particles.
  • the lignin derivative may be added in a proportion of about 1 to about 20% w/v of water, preferably between about 3 to about 10%, and more preferably between about 5 to about 8%.

  • the at least one micronutrient is added in the amounts specified. Because the algal extract may include some amounts of micronutrients, the total content of a micronutrient in the composition may be higher than that added.

  • the extraction process may be a low-temperature, low pressure process to avoid altering the natural compounds in the kelp plant.
  • extraction methods include steps such as In general, extraction procedures include maceration, digestion, decoction, infusion, percolation, solvent extraction, superficial extraction, ultrasound-assisted, and microwave- assisted extractions, known to those skilled in the art. However, the conditions may encourage mild glycosidic activity to increase the relative proportion of oligosaccharides ( ⁇ 12 monosaccharide units) compared to the polysaccharide (>12 monosaccharide units) component of the extract.
