Iperen IPE® | 11 - 44 - 11 + TE is a pure WS NPK with a high level of Phosphate combined with EDTA chelated micronutrients. Due to the Iperen IPE-Technology the Phosphate efficiency is comparable to 10 - 52 - 10 + TE. Our product has a limited caking sensitivity and is recommended during root and shoot development. The Iperen IPE Technology in our formula releases soil fixated Phosphates and overcomes the precipitation of fresh applied Phosphates. The IPE-effect has been proven in many scientific trials. Today IPE Technology is used globally to better manage Phosphates needs. Produced in our own plant TTD.

Fertilizing Knowledge

How can Iperen IPE® improve NUE?

Managing Phosphate for your crop can be a challenging task. Similar to Micronutrients, Phosphates are sensitive to soil fixation, making them unavailable for the plant. To reduce fixation, localized application will help, but this is not always sufficient. This is why we developed Iperen IPE® Technology to better manage Phosphate and Micronutrients efficiency.
