Description

Enforce® Substra is a NPK complex fertilizer with ISODUR® slow-release nitrogen, potassium sulfate, magnesium and trace elements.
It is a long-life complete fertilizer for various applications with a focus on the use in professional growing media as a base fertilization and to buffer N-fixation in peat-reduced substrates. The nutrient composition is also suitable for use with ornamental plants, trees and horticulture. Enforce® Substra contains the long-term nitrogen form isobutylidene diurea nitrogen (IBDU - ISODUR®). This long-term nitrogen form ensure the effect for many weeks, high N efficiency and lead to good growth and coloration. Each grain contains all nutrients and thus guarantees a very exact distribution of the main and secondary trace nutrients.

Sustainable Production

CO2-Reduction: 353 kg CO2e/t Product produced

Low-Carbon Footprint

Since 2024, COMPO EXPERT has been using low-carbon raw materials to reduce the carbon footprint of many specialty fertilizers for the Central European market.

The here reported reduction is achieved using low-carbon sources of nitrogen, potassium, magnesium, and/or sulfur, which have a lower carbon footprint compared to the respective market average (-60% for nitrogen and -90% for potassium, magnesium, and sulfur). This reduction was certified by our suppliers and validated there by an independent certification body. The percentage reduction applies exclusively to the raw material components listed; it does not apply to the entire life cycle of the finished product.

Emissions data from the respective European production of the raw materials, as found in the ecoinvent 3.11 database, serve as a reference for the market average in this comparison.
