  • Publication number: 20020121046
    Abstract: Composition for and method of stimulating growth of plants, e.g. increase in crop production. The composition comprises a carbon skeleton/energy component, typically a sugar or mixture of sugars; a macronutrient component providing the elements nitrogen, phosphorus, potassium and calcium, preferably also magnesium and sulfur; a micronutrient component providing zinc, iron and manganese, preferably also copper, boron, molybdenum and cobalt. The composition also preferably contains a vitamin/cofactor component and an enhancement component. The composition may be in the form of an aqueous solution or in a form suitable for coating seeds or coating pollen. It may be applied as a foliar spray, as a soil amendment, as a root dip or as an injectable solution. Preferably where, for example, it is used as a foliar spray it is applied at intervals at different stages of growth.

  • Patent number: 6336772
    Abstract: Compositions for and method of degrading organic chemicals in soil. The composition is a nutrient medium serving as a substrate for micro-organisms in the soil, preferably containing a major proportion of a source of carbon skeleton and energy, a macronutrient component preferably including nitrogen and other macronutrients, and a micronutrient component, preferably also a complexing agent and a vitamin/co-factor component. This nutrient material is added to soil, e.g. soil contaminated by a pesticide, to cause proliferation of micro-organisms which are effective, or which develop effectiveness to degrade the organic chemicals. Preferably the micro-organisms are those naturally present in the soil but useful micro- organisms may be added with the nutrient medium.

  • Patent number: 5696094
    Abstract: A method of controlling soil borne pests and pathogens, e.g., nematodes in which a predisposition material is incorporated in the soil which predisposes the pests or pathogens by weakening their resistance to attack by soil microbes. The predisposing material may be a lignosulfonate or other organic material which penetrates the cuticle of the pests or pathogens and renders them more amenable to attack by soil microbes. Preferably the predisposition material is accompanied by nutrient material such as a sugar, which may be a natural accompaniment of the predisposition material as in the case with lignosulfonates and/or which may be added. Preferably also the predisposition material is accompanied by macronutrients such as nitrogen and phosphorus macronutrients, also micronutrients and vitamin/co-factor.
