Active Carbon Technology – technology for intensification of rhizosphere processes (rhizosphere management).
The technology is based on the concept of rhizosphere management – management of the plant's rhizosphere – the soil zone surrounding the root and in close relationship with root secretions (exudates) and soil microflora (bacteria, fungi and other organisms). The concept is to maximize the efficiency of root processes, to increase the utilization rate of nutrients by plants, and not to increase the rates of chemical fertilizer application.
The ACTion complex, in terms of its biological activity, has a similar effect to plant root exudates, which stimulate rhizosphere processes:
- Increases soil microbial activity and improves nutrient absorption.
- Provides an available source of energy (carbon) for soil, microbiota, and crops.
- Stimulates the development of the root system.
- Activates stress resistance in the initial stages of development.
- Buffer agents in ACTion contribute to the mobilization of phosphorus and other elements from the soil and applied fertilizers.
The "root-rhizosphere microflora" system is formed immediately after seed germination. Applying Quantum Diaphan starter fertilizers with ACTion technology during sowing contributes to:
- Active colonization of the root zone even before seed germination and stimulation of microflora reproduction even under unfavorable conditions for its growth.
- Increasing the availability of nutrients both through the direct effect of ACTion components on the mobility of hard-to-reach elements and indirectly through stimulation of the vital activity of rhizosphere microflora.

Natural plant metabolites and biologically active substances at the heart of ACTion have a direct stimulating effect on the plant by activating the growth of the root system and soil microflora, as well as by increasing the mobilization of nutrients from the soil and their availability through changes in chemical and biological processes in the rhizosphere.
