Abstract
Process for improving the plant growth with the aid of ion exchanger fertilizers, comprising adding to the growth medium weakly basic anion exchangers which are charged with anionic chelate complexes of micronutrient cations and macronutrient and micronutrient anions to the extent of at least 60% of their total capacity together with weakly acid cation exchangers charged with nutrient cations to the extent of at least 60% of their total capacity. Furthermore fertilizers comprising a mixture of weakly basic anion exchanger which are charged with anionic chelate complexes of micronutrient cations and other micronutrient and macronutrient anions to the extent of at least 60% of their total capacity and weakly acid cation exchangers which are charged with nutrient cations to the extent of at least 60% of their total capacity.
