Definitions

  • the present invention relates to aqueous compositions which contain micronutrients for plants, a process for increasing plant growth and the use of alkoxylated fatty acid esters to increase the penetration of micronutrients in plants.
  • micronutrients In addition to water, nitrogen and carbon dioxide, plants need so-called micronutrients to grow, albeit in small quantities. This includes inorganic or organic compounds of manganese, calcium, iron, magnesium, selenium, cobalt, nickel and zinc, which only have to be available to the plants in very small quantities, but which are nevertheless essential for plant growth. Common full fertilizers therefore contain e.g. also these connections for an adequate supply of the plants.
  • the micronutrients which are often also applied separately in the form of aqueous formulations, are not always absorbed to a sufficient extent by the plants, in particular because of the relative impermeability of the wax-containing, hydrophobic cuticle of the plant leaves. Therefore, relatively highly concentrated agents, which are therefore comparatively expensive, are often necessary in order to enable the plants to be adequately supplied with the essential nutrients.
  • aqueous compositions which contain micronutrients for plants and alkoxylated fatty acid esters determined as emulsifiers permit a very high penetration of these active substances into the plant.
