Definitions

  • This invention relates to a method of making a chelating and complexing agent for plant micronutrients such as zinc and iron.
  • the synthetic chelating agents are very expensive. It is also believed that they do not assist the plant in taking up or translocating the micronutrients from the leaf or ground into the plant.
  • the long-chain natural organic chelating or complexing agents particularly humic and fulvic acids do help the plant in translocating the micronu ⁇ trients. They are pH sensitive, however. Humic acid, for example, cannot be mixed with fertilizers that are acid or neutral because humic acid is insoluble in anything other than bases.
  • chelated metal salts using these chelating agents tend to fall out with time giving the chelated compound a relatively short shelf life.
  • the key factor is control of the pH to oxidize the ore and put into solution certain selected humic acids along with the waxes, resins, and fatty acids, then continuing the oxidizing process to drive off the waxes, resins, and fatty acids leaving a supernatant of selected humic acids with a pH of about 3 that is substantially free of impurities.
  • a cellulose material such as, peat, lignite, or leonardite ore, is finely ground and mixed with alcohol, either methyl or ethyl, and a sufficient amount of an oxidizing agent, such as a mineral acid, to oxidize the ore.
  • a mixture of 45 gallons of methanol, 95 lbs. of concentrated nitric acid, and 500 lbs. of leonardite ore This produces a thin slurry.
  • the amount of methanol can be reduced, but it is important that the ore be sufficiently wetted with the acid-methanol mixture to have a paste-like consistency.
  • the ore is a well weathered, leonardite ore, and the oxidizing acid is nitric acid, although citric, acetic, tartaric, oxalic, ascorbic and phosphoric acids could also be used.
  • the resulting mixture is allowed to stand, preferably in the sun as much as possible, with occasional stirring, to allow the alcohol to evaporate as the ore oxidizes.
  • the alcohol retards the oxidation process allowing it to progress slowly over a period of time without the violent reaction that would otherwise occur. This process can be shortened by adding heat.
  • the methanol has evaporated, the remaining dry ore will continue to oxidize. As it does,. the pre turns reddish-brown. With sufficient time all of the ore will turn reddish-brown indicating that it is sufficiently oxidized for the sequen ⁇ tial extraction of the chelating solutions from the ore. During the summer this will take about two weeks.
  • the ranges of the ingredients are between 80-95% water, 5-15% ore, 2-6% hydrogen peroxide, and 1% or less of the base.
  • the accumulated supernatant is an excellent chelating agent. It can be used alone or mixed with about twenty percent sodium citrate or citric acid depending on the desired pH. This produces a somewhat more stable product.
  • EXAMPLE III To obtain a 35.5 dry zinc chelated material, the supernatant from Example I above is mixed with 36% zinc sulfate. Five pounds of the chelating agent is used with 100 lbs. of the zinc sulfate. The components are mixed well and then let dry. This will leave about 101.4 lbs. of material containing 35.5% chelated and complexed zinc.
  • one of the advantages of the chelating and complexing agent is the small amount required.
  • one pint will produce twelve gallons of a chelated micronutrient in the following percentages: 7% zinc, 5% iron, 5% manganese, or 5% copper.
  • the chelating agent obtained by the method of this invention acts to increase the ability of the plant to translocate the micro ⁇ nutrients into the plant. This is done by affecting the semi-permeable membranes of the plant cell, thereby enabling ions to pass through it more easily.
  • the product also reduces the surface tension of water and therefore is a mild wetting agent.
  • one of the great advantages of the product produced by the method of this invention is that it forms a stable, water soluble, complex with divalent and trivalent metal ions that is not pH sensitive and can be mixed with either basic or acid fertil ⁇ izers.
  • the leaves contained 79 parts per million. In the plot sprayed with the material of this invention, the leaves contained 119 parts per million, thereby demonstrating dramatically the ability of the product of this invention to assist the plant in taking up micronutrients.
