Definitions

  • the present invention relates to compositions which supply essential elements for preventing and correcting nutritional deficiencies in plants.
  • the present invention relates to compositions which supply essential elements for use in agriculture, for the prevention and cure of physiological alterations or nutritional unbalances in plants.
  • This field also comprises a study of plant interactions, nutrients and pathogen agents which, due to their complexity, have not yet been completely understood. Although often neglected, nutrition has always represented a fundamental component for disease control. Most terrains and environments dedicated to cultivations contain a large number of pathogens which can be more virulent on plants with nutritional deficiencies and consequently more susceptible to external attacks . A correct crop nutrition must therefore be based on products having a maximum efficiency, distributed in adequate dosages, appropriate times and with equally efficient methods.
  • EDTA ethylene- diaminotetra-acetic acid
  • HEDTA hydroxyethylenediamino- triacetic acid
  • DTPA diethylenediaminopenta-acetic acid
  • EDDHA ethylenediamino-di- (o-hydroxyphenyl) acetic acid
  • EDDHSA ethylenediamino-di- (o- hydroxy-4 -methyl-phenyl) acetic acid
  • LSA ammonium ligninsulfonate

  • Nitrogen is preferably present in the form of ammonia or in the form of quaternary ammonium salts .
  • compositions which supply essential elements according to the present invention are their high selectivity. They can in fact be administered either through the leaf or via the root by means of burial or an injector spade, they can be used in fertirrigation even in terrains with an alkaline pH and in particular and effectively, by means of micro-irrigation systems such as hoses and drippers, without any phytotoxicity .
  • a further advantage is that the above compositions which supply essential elements allow excellent results to be reached with a limited treatment cost.
  • compositions which supply essential elements according to the present invention have a negli- gible environmental impact and an excellent toxicological profile, thanks to their characteristics and biodegrad- ability. This allows their insertion in modern nutritional programs and, in particular, in integrated production programs .

  • the copolymeric compounds containing acid functions obtained by the copolymerization of mono- or oli- gosaccharides with acids or their monounsaturated mono/polycarboxylic derivatives and/or with monounsaturated sulfonic acids and/or with monounsaturated phos- phonic acids, can be selected from copolymers obtained by the copolymerization of glucose and acrylic acid; fruc- tose and acrylic acid; palatinose and acrylic acid; leucrose and acrylic acid; saccharose, acrylic acid and methallylsulfonate; saccharose, acrylic acid, methallyl- sulfonate and acrylamide,- saccharose, maleic anhydride, phosphorous acid and sodium hydrogen sulfite,- or saccha- rose, maleic anhydride, iron ammonium sulfate (II) .
