Natural fertilizers
Natural fertilizers are fertilizers derived from natural or bio-based sources and closely aligned with natural soil and plant processes. They provide nutrients in a way that strengthens the soil while feeding the crop.
In an agricultural sector increasingly focused on sustainability and circular thinking, natural fertilizers play an important role in maintaining soil health and reducing environmental impact.
What are natural fertilizers?
Natural fertilizers consist of raw materials of biological origin, such as animal manure, plant residual flows, compost, or digestate. These fertilizers contain, besides nutrients, also organic matter, which is essential for a well-functioning soil.
Due to their natural composition, these fertilizers better match the needs of soil life and plants.
Difference from synthetic fertilizers
Unlike synthetic or highly processed fertilizers, natural fertilizers release their nutrients gradually. This reduces the risk of leaching and makes the nutrition better suited to the crop's uptake capacity.
Moreover, natural fertilizers contribute to building organic matter and a stable soil structure.
Effect on soil structure and soil life
A key benefit of natural fertilizers is their positive influence on soil structure. Organic matter improves soil crumb and increases water retention capacity.
Additionally, natural fertilizers stimulate soil life, such as bacteria and fungi, which play a key role in releasing nutrients.
Combination with biostimulants
Natural fertilizers are increasingly combined with biostimulants. Biostimulants enhance natural processes in soil and plant and ensure that nutrients from natural fertilizers are used more efficiently.
This combination results in stronger roots, better growth, and increased stress resistance.
Role within sustainable and circular agriculture
Within sustainable and circular agricultural systems, natural fertilizers form an important link. Residual flows from agriculture and industry are given new value and used to improve soil and crops.
This keeps nutrients within the chain and reduces dependency on fossil resources.
Practical application
The use of natural fertilizers requires a thoughtful strategy. Factors such as soil type, crop choice, organic matter content, and regulations determine which products are most suitable.
Regular soil analyses can monitor and optimize the effect of natural fertilizers.
Summary
Natural fertilizers support healthy soils, efficient nutrient utilization, and sustainable cultivation. Combined with biostimulants, they provide a solid foundation for future-proof agriculture.
