Testing organic-carbon fertilizers that improve soil water retention, reduce heavy metals, and stabilize crop quality under extreme climates

Complexor Sp. z o.o. is a manufacturing company specializing in the development and production of high-quality fertilizers containing organic carbon, designed to improve the physicochemical properties of soil, crop quality, and the resilience of agricultural systems to climate change.

Within the context of the HORIZON-MISS-2026-08-CLIMA-SOIL project, Complexor plans to focus on the practical demonstration and field testing of carbon-based fertilizers, with particular emphasis on:

• increasing soil water retention and rainfall capture, thereby mitigating the effects of drought and intense precipitation,

• improving soil structure and the stability of soil aggregates,

• reducing the bioavailability of heavy metals through their immobilization in the soil matrix,

• enhancing crop quality and food safety, especially on degraded soils or those exposed to climatic stress,

• assessing the long-term impact of carbon-based fertilizers on soil health and crop productivity.

Complexor contributes to the consortium with expertise in fertilizer production, quality control, and the organization of field trials, supporting the objectives of the EU Soil Mission through the implementation of agroecological solutions.
