ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an manure, and particularly, a fertilizer with a chelate element comprising an oxycarboxylic acid and a metal.
2. Description of the Prior Art
Fertilizers are applied to soil to supply nutrition to agricultural products for increasing the yield and to prevent degradation of the fertility of the soil. It is known to supply, to soil, large amounts of three major manurial components of nitrogen (N), phosphorus (P) and potassium (K) indispensable for growth of plants. Nitrogen serves to promote synthesis of protein in a plant, division and multiplication of cells, growth of the roots and sufficient upgrowth of the leaves and stems and to advance absorption and the anabolism of the nutrition. Phosphorus is effective to accelerate growth of the roots to increase the nutrition absorbing area of them and to activate the germination. In addition, it contributes to hasten maturation of plants and increase the yield of seeds and fruits. Also, phosphorus is useful to enhance generation of starch and activity of the enzymes and microorganisms, to prevent noxious insects and to improve quality of the harvest. Potassium is efficacious to synthesize carbohydrates and nitrogen compounds, to promote anabolism, growth of the roots, flowering and fruitage to adjust evaporation of the water supplied and to increase the resistance to damages by cold weather and harmful insects. In addition to three major manurial components, the fertilizer may contain calcium (Ca), magnesium (Mg), silicon (Si), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo), iron (Fe), and boron (B) to directly or indirectly assist the good growth of plants.
Any fertilizer is required to contain larger amounts of effective components, without disadvantageous, substances so that it allows large scale production of crops through easy treatment and inexpensive process with a low hygroscopicity and caking. In recent years, upgraded agricultural products have been required at a request of consumers who require high quality of crops with good appearance in color and luster, excellent aroma and delicious taste. Also, the consumers have needed the medicinal efficacy of the agricultural products which satisfies their health desire so that the fertilizers must be ameliorated to improve quality of the agricultural products.
An object of the present invention is to provide a fertilizer which contains a chelate effective to cultivate agricultural products with their good color, excellent aroma and delicious taste as well as antiseptic and fungicidal. Another object of the present invention is to provide fertilizer with a chelate element capable of cultivating agricultural products which can generate active enzymes in a living body ingesting the products so that the active enzymes are effective to detoxify hydrogen peroxide, organic peroxides, carcinogenic substances with anti-oxidation.
SUMMARY OF THE INVENTION
The fertilizer according to the present invention comprises on the basis of weight 0.01 to 4 parts of a compound of metal for forming the central metal of the chelate, 1 to 5 parts of an oxycarboxylic acid, 2 to 8 parts of a potassic element, 0.1 to 1 part of a nitrogenous element, and 0.01 to 2 parts of a phosphorus element to provide a pH value of 6.0 to 7.5 when mixed with water. When a living body ingests the agricultural product cultivated with the fertilizer, the chelate can derive glutathione S-transferase (GST) molecular species which catalyze the detoxicating reaction of the electrophillic compound by the S-bonded reaction of the electrophillic compound and nucleophillic reduction-type glutathione peroxidase.
When the chelate comprises oxycarboxylic acid and metal, it can constitute enzymes which would produce various detoxifying and anti-oxidation effects, because the chelate provides an active center incorporated in the peptide chain to be subjected to oxidation-reduction in substrate. The generated enzymes act as a catalyst for reduction reaction into water or alcohol of hydrogen peroxide water, organic peroxides, and other highly reactive electrophillic compound. The electrophillic compound is derived from hydroxylation of various medicines comprising a chemical carcinogen, and the electrophillic compound causes mutation, carcinogenesis, a cytotoxic effect and the like, when it produces a covalent bond with the nucleophillic portion of DNA or protein, but, if a living body ingests an agricultural product cultivated with the fertilizer according to the present invention, the chelate certainly derives an active enzyme or glutathione S-transferase (GST) molecular species which can catalyze the S-bonded reaction of an electrophillic compound and nucleophillic reduction-type glutathione peroxidase (GSH) for detoxification.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Detailed embodiments of the fertilizer according to the present invention are described hereinafter.
The fertilizer with a chelate element according to the present invention, comprises on the basis of weight 0.01 to 4 parts of a compound of metal for forming the central metal of the chelate, 1 to 5 parts of an oxycarboxylic acid, 2 to 8 parts of a potassic element, 0.1 to 1 part of a nitrogenous element, and 0.01 to 2 parts of a phosphorus element, providing a pH value of 6.0 to 7.5 when mixed with water. The fertilizer can derive glutathione S-transferase molecular species when a living body ingests an agricultural product cultivated with the fertilizer.
If the amount of the compound of metal is under 0.01 part or if the amount of the oxycarboxylic acid is under 1 part, no chelate compound will be generated. Although the amount of the compound of metal exceeds 4 parts, the effect of the fertilizer would be kept unchanged, but it must be required to prevent contamination of the soil by an excessive amount of the compound of metal accumulated therein. The amount of the oxycarboxylic acid over 5 parts will disadvantageously make the chelate compound unstable. The amount of the potassic element under 2 parts will prepare no sufficient amounts of carbohydrates and nitrogen compounds. The amount of the nitrogenous fertilizer under 0.1 part will generate no sufficient amount of protein. The amount of the phosphorus element under 0.01 part will be unable to sufficiently promote growth of the roots of agricultural products. The amounts of potassic element over 8 parts, nitrogenous element over 1 part, and phosphorus element over 2 parts will undesirably supply an excessive amount of the fertilizer in the soil with unchanged physiologic action of each fertilizer and with a possible ill effect on the soil. The. pH value of the fertilizer under 6.0 will result in possibility of the soil contamination due to the excessive acidity, and the pH value over 7.5 will affect the stability of the complex.
The fertilizer may further comprise at least an additional acid selected from the group of saccharic acid, fatty acid and mixture thereof in the total amount: 1 to 5 parts of the oxycarboxylic acid and the additional acid. The compound of metal is selected from groups of germanium compound, selenium compound and mixture thereof. Specifically, the fertilizer may comprise 0.05 to 2 parts of germanium acetate as the chelate element, 1.5 to 2.5 parts of glyceric acid as the ocarboxylic acid, 5 to 7 parts of a potassic element, 0.1 to 0.5 parts of a nitrogenous element, and 0.03 to 1 part of a phosphorus element by weight to provide a pH value of 6.8 to 7.3 when mixed with water. Otherwise, the fertilizer may comprise 0.03 to 2 parts of selenium trioxide (SeO
3
) as the chelate element or a compound of metal, 0.5 to 1.5 parts of citric acid, 0.5 to 1.5 parts of pentaric acid as a saccharic acid, 0.5 to 1.5 parts of acetic acid as a fatty acid, 3 to 5 parts of a potassic element, 0.3 to 0.8 parts of a nitrogenous element, and 0.5 to 1 part of a phosphorus element by weight to provide a pH value of 6.3 to 7.0 when mixed with water. The fertilizer may comprise at least an additional acid selected from
