In the field of research and development, highly qualified engineers are constantly working on innovative technologies and products, which allow to bring new alternative chelated Micronutrient solutions to the market.


We work together with several innovative top specialists in production and development of chelated Micronutrients. They develop completely new types of chelating agents and innovative production processes. Only three complexing agents were added to the list of the European Fertilizer law over the past 20 years. Our main partner on Micronutrients developed two of them: IDHA and HBED.

Oligo Zinc-IDHA 10%

Van Iperen Oligo Zinc-IDHA 10% is a highly pure 100% chelated zinc fertilizer, part of our in-house IDHA chelated product range, designed to counter Zinc deficiency disorders on all crops.

Our patented IDHA chelating agent is the only biodegradable alternative to the classic chelates such as EDTA. It is mainly advised in foliar application. Soft on the leaf tissue, it doesn't leave any residues inside the plant, after it breaks down into naturally occurring plant components.
It is worthy to note that IDHA is a chelating agent, and not a complexing agent, having by far superior stability constant compared to other such alternatives on the market, thus the higher efficiency.

Made in EU with outstanding quality, the product is micro-granulated, dust free and user friendly.
