Hemp: The eco-friendly crop perfectly suited for organic farming
The rising popularity of organic hemp is no coincidence. The plant's unique agricultural properties make it particularly well-suited for organic farming practices. With 56% of all hemp fields in Germany organically farmed, compared to just 3% for wheat, hemp's resurgence is impressive.
For centuries, hemp was a significant crop in Germany, valued for its versatility. The plant, known botanically as Cannabis sativa, was used for everything from rope and paper to textiles and food. However, concerns about the psychoactive effects of its flowers led to a ban on its cultivation in 1982.
It wasn't until 1996 that hemp made its legal comeback, albeit with stringent restrictions. Only varieties with a tetrahydrocannabinol (THC) content of less than 0.2% were permitted, ensuring that the crop cannot be used for the production of marijuana or hashish.

Despite these regulations, hemp has slowly but steadily reclaimed its place in German agriculture. According to the Federal Statistical Office about 56% of all hemp fields in Germany are organically farmed, a striking contrast to other crops like wheat, where the organic share is a mere 3%.
Why hemp is the perfect crop for organic farming
Robustness and natural weed suppressor
The rising popularity of organic hemp is no coincidence. The plant's unique agricultural properties make it particularly well-suited for organic farming practices. Unlike many conventional crops, hemp requires minimal input, thriving without synthetic fertilisers, herbicides, or pesticides. This resilience makes it a natural fit for organic farming, where the use of chemical interventions is restricted.

One of the most significant environmental benefits of hemp is its ability to naturally suppress weeds. Hemp grows rapidly and forms a dense canopy that covers and shades the soil early in the season, effectively outcompeting weeds and reducing the need for mechanical or chemical weed control. This characteristic is crucial in organic farming, where maintaining soil health and biodiversity is paramount.
Hemp's robust resistance to pests and diseases further enhances its appeal for organic cultivation. The plant rarely falls prey to the common pests that plague other crops, meaning that farmers can avoid using pesticides, a core requirement of organic certification. This natural resilience also reduces the risk of crop loss, making hemp a reliable option for organic farmers.
Soil health and hemp’s role in regenerative agriculture
Hemp's deep root system is another vital attribute that makes it ideal for organic farming. Its roots can penetrate several metres into the soil, breaking up compacted layers and improving soil structure. This deep rooting not only enhances the soil's physical properties but also helps in accessing nutrients and moisture from deeper soil layers, reducing the need for irrigation and fertilisation. In organic farming, where soil health is a critical focus, hemp’s ability to enhance soil structure and fertility makes it an invaluable crop.

Moreover, hemp is an excellent precursor in crop rotations. Its deep roots help to aerate the soil and improve its overall structure, which benefits subsequent crops. The plant also leaves behind a substantial amount of organic matter, enriching the soil and boosting its fertility. This makes hemp particularly beneficial when planted after legumes or clover, crops that also contribute to soil health through nitrogen fixation.
In addition to its direct benefits to the soil, hemp’s ability to capture carbon dioxide from the atmosphere and store it in the soil aligns with the goals of regenerative agriculture. This process not only contributes to mitigating climate change but also enhances the long-term sustainability of farming systems.
Hemp’s versatility and low environmental impact
The entire hemp plant can be utilised, adding to its appeal for organic farmers. The versatility of hemp as a crop extends to its low environmental impact and the multitude of uses for its byproducts.
The seeds are highly valued for producing nutrient-rich oil, which has found a strong market among health-conscious consumers. The fibres are used in various sustainable products, from textiles to construction materials, further reducing the environmental footprint of the agricultural sector. The woody core, or hurds, can be used as animal bedding or in eco-friendly building materials, further supporting the crop's sustainability credentials.
Because the entire hemp plant can be utilised, waste is minimal. This full utilisation is a key component of sustainable farming practices, where the goal is to make the most of every part of the plant to minimise environmental impact.
Conclusion
Hemp's potential as a sustainable crop is undeniable. Its adaptability, resilience, and minimal environmental impact, tribute to soil health, and provide a wide range of sustainable products make it a model crop for organic farming.
As the demand for organic products continues to grow, so too will the opportunities for hemp. For farmers looking to diversify their operations with a crop that is both eco-friendly and economically viable, hemp offers a compelling option because it’s not only a crop that is well-suited to their farming practices but also one that can contribute to a more sustainable and resilient agricultural system.
