Definitions

  • the present invention relates to a plant fertilizer composition.
  • Iodine is an essential trace element for mammals. Lack of iodine in the human diet results in negative0 effects on human health. It is known from studies by the World Health Organization that a third of the world population (35 %) suffers from iodine deficiency disorders. These disorders result in endocrinological problems such as goiter or enlargement of the thyroid,5 cretinism or a form of mental retardation, risk of stillbirth and spontaneous abortion during pregnancy and growth impairment.
  • adeguate selenium nutrition0 supports efficient thyroid hormone synthesis and metabolism and protects the thyroid gland from damage by excessive iodine exposure.
  • normalization of iodine supply is mandatory before initiation of5 selenium supplementation in order to prevent hypothyroidism (Zimmermann MB, K ⁇ hrle J. Thyroid, 2002
  • the World Health Organization recommends the0 following daily iodine intake for the following population groups : Table I
  • Iodine has been supplemented through iodized salt and oil.
  • Iodine has been supplemented as potassium iodate and potassium iodide. Because iodate is more stable under extreme climatic conditions it is preferred to iodide, especially in hot and humid climates (WHO, UNICEF and ICCIDD, Recommended iodine levels in salt and guidelines for monitoring their adequacy and effectiveness. Geneva, World Health Organization, 1996 (WHO/NUT/96.13) ) .
  • the artificially added iodine results in amounts of at least 10 p. p.m. of iodine in the total dry mass of the fertilizer so as to be effective in providing improved iodine uptake by the human consumer of the edible plant part(s) grown on this fertilizer.
  • the amounts of iodine added are preferably chosen to be of a level that meets the recommended daily iodine intake to a significant level with regular food intake quantities of vegetables and fruits.
  • the fertilizer is a solid fertilizer, for example in the form of crystals or prills with artificially added iodine containing substances homogeneously distributed over the solid mass meaning that the relative amount of iodine to the total mass for each particle of the fertilizer is practically identical.
  • This formulation provides as a benefit the guaranteed even distribution of iodine in the total fertilizer solution after dissolution in water.
  • the invention also concerns methods for manufacturing a plant fertilizer comprising the step of adding iodine to a basic solid fertilizer and homogeneously distributing the added iodide or iodate in the solid plant fertilizer.
  • the preferred methods for adding iodides differ from the preferred methods for iodates since iodides decompose more readily at higher temperatures to iodine which is then lost as a gas.
  • Methods were developed to add iodides or iodates to solid fertilizers such as nitrates, in either the shape of prills or in the shape of crystals.
  • the preferred method for adding iodide is to dissolve iodide in the coating solution of the anti-caking and anti-dust additive, in a manufacturing step.
  • the preferred method for adding iodate is to add the iodate to the molten fertilizer crystals before prilling.
  • the preferred method for adding iodide or iodate was to premix iodide or iodate in the anti-caking and anti-dust coating solution during manufacturing.
  • figure 1 schematically represents a method for manufacturing a fertilizer according to the invention adding iodine in the form of iodide to a basic solid plant fertilizer that is shaped in the form of prills;
  • figure 2 schematically represents the same as figure 1 but for adding iodine in the form of iodate instead of iodide;
  • figure 3 schematically represents a method for manufacturing a fertilizer according to the invention by adding iodine containing substances to a basic solid plant fertilizer that is shaped in the form of crystals.
  • the method shown in figure 1 starts from a basic fertilizer 1 in the shape of crystals 2 such as nitrates, that are prilled into prills 3 after melting the crystals according to known methods.
  • the method additionally comprises the step of adding iodine in the form of iodide 4 to an anti-caking and anti-dust solution 5 used to provide the prills with a coating 6 containing iodide, resulting in a solid plant fertilizer 7 according to the invention.
  • the application of the iodide in the form of a coating on the fertilizer prills results in a homogeneous distribution of iodine in the fertilizer, thereby ensuring a constant ratio of iodine to nitrate.
  • the concentration of the added iodine in the form of iodide 4 is preferably at least 10 p. p.m. of the total dry mass of the solid fertilizer 7.
  • potassium nitrate fertilizer containing 91 and 130 p. p.m. potassium iodide applied at a dose rate of 1,29 grams of potassium nitrate per litre nutrient solution in order to obtain 90 and 129 microgram I/litre nutrient solution, lettuce was grown and was shown to have taken up sufficient iodide to provide 26-31 % of the WHO daily iodine intake recommendation of 150 ⁇ g iodine (I) , or 39 tot 46 ⁇ g I when a portion of 60 gram of lettuce leaves would be consumed.
  • selenium containing substances can be added to the fertilizer 7, since a good selenium and iodine balance is essential for sufficient hormone production in humans. In order to be effective, a level of at least 5 p. p.m. of selenium in the mass of the dry fertilizer is desirable .
  • Figure 2 shows the preferred method for manufacturing using alkali metal or alkaline earth metal iodates which are added to the molten crystals such as nitrates, which are subsequently turned into uncoated prills, which in a final step are then coated with an anti-caking and anti-dust additive solution.
  • the method shown in figure 2 also starts from a basic fertilizer 1 in the form of crystals 2 that are transformed into prills 3 by melting, whereby- according to the invention the iodine is added in the form of iodate 8 (KI03) to the molten crystals before prilling them.
  • the obtained prills are then further coated with an anti-caking and anti-dust solution 5 to obtain a final fertilizer 7 comprising prills 3 with homogeneously distributed iodine and coated with an anti-caking and anti-dust coating 6.
  • the method shown in figure 3 is an alternative method according to the invention to add iodine in the form of iodide or iodate to a basic plant fertilizer in the shape of crystals 2.
  • the alkali metal or alkaline earth metal iodide 4 or iodate 8 is added in a premix containing anti-caking and anti-dust agents 5 which is then added to the crystals as a coating 7.
