Abstract
Abstract A fertilizer for the long term and uniform supply of plants with micronutrient elements of atomic numbers 24 to 30, comprising at least one anion exchanger charged with anionic chelated ions of at least one element having having an atomic number of from 24 to 30; furthermore a process for the long term and uniform supply of plants with micronutrient ions of elements of atomic numbers 24 to 30, wherein an anion exchanger charged with said ions is applied to the plants or their environment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
61 words
A process for the long term and uniform supply of plants with micronutrient ions of elements of atomic numbers 24 to 30, wherein an anion exchanger charged with anionic chelated ions of at least one element of the group consisting of elements having an atomic number of from 24 to 30 is applied to the plants or their environment as fertilizer.
Claim 2
Dependent Claim
61 words
A process for the long term and uniform supply of plants with micronutrient ions of elements of atomic numbers 24 to 30, wherein an anion exchanger charged with anionic chelated ions of at least one element of the group consisting of elements having an atomic number of from 24 to 30 is applied to the plants or their environment as fertilizer.
Claim 3
Dependent Claim
23 words
