Organic fertilizers are fertilizers that are permitted within organic farming and are compatible with strictly regulated, sustainable cultivation systems. They are based on natural raw materials and support both the crop and the soil ecosystem.

Within organic farming, the focus is not only on direct crop nutrition but mainly on maintaining and enhancing soil health in the long term.

What are organic fertilizers?

Organic fertilizers are naturally derived fertilizers that meet the requirements of organic certification systems. They must contain no synthetic or chemically processed components and are intended to support the natural fertility of the soil.

These fertilizers deliver nutrients in a form that becomes available to plants slowly, tailored to natural soil processes.

Difference between organic and conventional fertilizers

Unlike conventional fertilizers, organic fertilizers are aimed at activating soil processes rather than rapidly making nutrients available. As a result, nutrient release is more even, and leaching is limited.

This contributes to stable growth and prevents disruption of soil life.

Impact on soil structure and soil life

Organic fertilizers have a positive influence on soil structure and stimulate soil life. Microorganisms play an important role in converting organic substances into plant-available nutrients.

An active soil life increases the natural resilience of crops and contributes to a healthy root environment.

Combination with biostimulants

Within organic farming, the use of biostimulants is becoming increasingly common. Biostimulants enhance the effect of organic fertilizers by further activating natural processes in soil and plants.

This combination supports root development, nutrient uptake, and stress resistance, without compromising organic principles.

Role within organic and circular farming

Organic fertilizers support both organic and circular farming systems. They utilize renewable raw materials and contribute to closing nutrient cycles.

Reusing residual streams as fertilizer creates a sustainable system with minimal external input.

Practical application

Applying organic fertilizers requires knowledge of soil, crop, and regulations. Organic growers often work with a multi-year strategy, focusing on soil building and monitoring.

Regular soil and crop analysis helps to apply the right fertilizers at the right time.

Summary

Organic fertilizers form an important foundation for organic cultivation. They support soil health, stable crop growth, and sustainable production, contributing to a future-proof agriculture.
