Further, the invention relates to binding the moisture content of soils, as well as composition for use in enhancing the efficacy of soil retaining compositions.
  • a number of methods for inhibiting the decrease of soil moisture-content have been provided, one form of which is the introduction of the most different humectants in the soil.
  • the common characteristic of these materials is that they easily bind the moisture while decrease the fast flow-out of the moisture from the area and the treated area, respectively.
  • Such materials have a characteristic equilibrium point.
  • Such materials are mainly organic compounds, such as glycols, polihydroxy alcohols, like glycerol and sorbitol.
  • compositions in the form of liquid concentrated solution for improved water supply of plant roots which essentially consist of an organic humectants, binding agent, wetting agent and water.
  • humectants for example sorbitol, molasses, potassium lactate, sodium lactate, glycerol, potassium acetate, sodium acetate may be used.
  • the composition may contain preferably a thickener, such as a cellulose ether derivative, hydroxyethyl cellulose, carboxymethyl propylcellulose and the like.
  • WO 90/13598 discloses a sprayable composition for covering, among others, soil, refuse at a dump site and other dangerous materials, which contains a water-soluble cellulose polymer forming a water-resisting layer after application, clay and a carrier, wherein the composition forms a tough, water-repellent and flexible layer, without penetrating in the soil.

  • the presence of iron oxide is mentioned.
  • compositions for stimulating plant growth which are applicable of energy introduction. These compositions comprise carbon source, a water-soluble macronutrient component providing nitrogen and phosphorous, and vitamin/cofactor component, optionally together with a micronutrient component, which latter may contain zinc, iron and manganese source.
  • iron source iron(II)oxide is mentioned.
  • US publication 2005/0111924 describes soil binding and revegetation compositions useful for inhibiting the erosion of soil, which comprises water, carbohydrate, protein, iron compound and a strong base, as well as a fibrous material comprising at least two different types of fibers; the pH-value of the compositions is strongly basic, characteristically 9 to 13, preferably 10 to 12,8.
  • iron compound iron(II) and iron(III)oxides and other iron salts are mentioned.
  • compositions contain binding materials, like lignosit, which is a hygroscopic adhesive and contains maize or potato dextrin, or alternatively, ligno-sulfonic acid calcium, sodium or ammonium salt may also be used.
  • wetting agent compounds known per se are mentioned, such as Triton products (Triton 101, Triton X100, Ninol II-CN, Igepal 60630, nonylphenol-(9-15)ethoxylate and the like.
  • soils contain iron in an amount of 1 to 5%, which is the fourth most occurring element in the Earth. Most part of the iron is present in silicate stones or as iron oxide or hydroxide, that is in forms which are hardly accessible for plants. In the soils the iron is present in Fe ++ and Fe +++ form, wherein especially the latter can be very difficult to be utilized by the plant, though it is essential for these.
  • the iron supply may be provided in traditional methods, by adding simple inorganic iron salts or complex iron compounds, this solution, however, needs frequent treatments as most of the materials used become lost, partly by being washed into and depositing in the deep layers of soil, and partly by taken up fast, mostly in an amount higher than required by the plant. It is especially important in case of dry soils.
  • iron deficiency of plants is difficult to correct as the iron present in the different nutritients (fertilizers) transform rapidly into a form unavailable for the plants in the soil.
  • some iron chelates proved to be useful, but very few chelates remain stable in a relatively broad pH range.
  • a small change in the moisture content results in a substantial change of pH value; thus, such methods are difficult to use.
  • a further advantage of the new solution according to the invention is the influence of the siderophore production by the plants and the microorganisms present in the soil in an indirect way, thus providing a more steady iron uptake for the plants.
  • microparticle iron(III)oxide also influences the soil bacterium activity in a preferable effect as not only the plants, but also the microorganisms utilize from the same source (pool). Increase of the microbiological activity provides additional benefit at the same time, as the mobility of other nutritient elements (such as phosphorous, nitrogen) is also increases thereby.
