Organic fertilization
Organic fertilization plays a central role in modern agriculture and the agro-industry. The concept encompasses solutions and applications that contribute to higher efficiency, sustainability, and economic value within agricultural production chains.
In circular and biobased systems, organic fertilization is becoming increasingly important. By smartly utilizing natural raw materials, residual streams, and innovative processes, dependence on primary input can be reduced while soil quality, yield, and product quality improve.
What is organic fertilization?
Organic fertilization refers to the application of nutrients in organic form, derived from natural or biobased sources. This can consist of animal manure, compost, digestate, plant residues, or specially developed organic fertilizers. Unlike purely mineral fertilizers, these products provide not only nitrogen, phosphate, and potassium, but also organic matter and often a wide range of micronutrients.
Due to these organic components, the soil is not only enriched but also structurally improved. The nutrients are gradually released, aligned with the crop's needs, minimizing losses through leaching.
Role of organic fertilizers
Organic fertilizers are at the heart of organic fertilization. They combine nutrient supply with soil improvement and contribute to building organic matter. Organic fertilizers can consist of a single raw material or blends of various biobased materials and residual streams.
Increasingly, organic fertilizers are developed with a predictable composition and functioning, making them better suited for modern cultivation systems and fertilization plans. This enables strategic and targeted use of organic fertilizers.
Organic matter and soil health
An important effect of organic fertilization is the increase and maintenance of organic matter in the soil. Organic matter forms the basis for healthy soil structure and active soil life.
- Improves crumb structure and root penetration.
- Increases the soil's water retention capacity.
- Buffers nutrients and reduces leaching.
- Stimulates microorganisms and soil fauna.
- Contributes to natural disease resistance.
A soil with sufficient organic matter is more resistant to weather extremes and offers crops a more stable growth base.
Combination with biostimulants
In addition to organic fertilizers, biostimulants play an increasingly important role in organic fertilization. Biostimulants are products that support natural soil and plant processes without primarily functioning as a nutrient source.
In combination with organic fertilization, biostimulants can:
- Accelerate the breakdown of organic matter.
- Improve nutrient availability.
- Stimulate root growth and root activity.
- Activate soil life.
- Increase plant resilience to stress.
Examples include humic and fulvic acids, microbial biostimulants, and extracts based on plants or algae. In combination with organic fertilizers, these products enhance each other's effect.
Organic fertilization within circular agriculture
In circular agricultural systems, organic fertilization is a key component for closing cycles. Residual streams from the food industry, animal feed sector, and bio-industry are converted into organic fertilizers and soil improvers.
This retains carbon and nutrient value within the agricultural chain and decreases dependence on fossil and primary raw materials. Organic fertilization thus serves as a connective link between production, processing, and cultivation.
Practical application and strategy
An effective strategy for organic fertilization considers soil type, crop plan, crop needs, and regional regulations. In practice, a combination of:
- A base application of organic fertilizers for organic matter and slow nutrient supply.
- Targeted supplements to correct specific deficiencies.
- Biostimulants to support soil processes and root development.
Through soil analysis, monitoring, and evaluation, the implementation of organic fertilization can be further optimized.
Economic and sustainable added value
Organic fertilization not only provides agronomic benefits but also economic and strategic value. It contributes to lower input costs, better utilization of residual streams, and achievement of sustainability goals.
For companies in the agricultural chain, organic fertilization offers opportunities to add value to biobased raw materials, reduce emissions, and develop future-proof production chains.
Organic fertilization as a foundation
Organic fertilization forms the foundation for healthy soils, resilient crops, and circular agriculture. By smartly combining organic fertilizers and biostimulants, a resilient system is created in which soil, plant, and chain optimally cooperate.
