Cannabis and Sustainable Farming
Cannabis and Sustainable Farming
Canada’s cannabis market is up for huge growth in the coming years, with revenue expected to reach an incredible US$4.70bn by 2024.
As the market progresses, so do the farming practices giving rise to interest in sustainable farming practices. In this article, we explore the integration of cannabis into sustainable farming for enhanced biodiversity and environmental sustainability.
Advantages of Companion Planting with Cannabis
Companion planting is a popular technique used for promoting sustainable farming practices. It involves the practice of growing different crops near one another for mutual benefit.
Let’s look at the two primary benefits of companion planting and understand a few reasons why you should try this on your farm too!
1. Pest Control
Cannabis is known to act as a natural pest repellent. It contains compounds such as terpenes and cannabinoids, which can deter pests.
By planting cannabis alongside other plants, you can create a natural barrier that can protect your garden from pests. Some specific pests that can be deterred by cannabis include spider mites, aphids, and whiteflies.
2. Soil Improvement
Cannabis plants have a deep root system that can help to break up compacted soil and improve soil structure. They also can absorb nutrients from deep within the soil and bring them to the surface, making them available to other plants.
By planting cannabis alongside other plants, you can improve the overall health and sustainability of your soil, which can lead to higher yields and healthier plants.
Cannabis and Crop Rotation
Crop rotation involves a systematic method of rotating crops in a particular field over some time. It’s been used for centuries, and the main objective is to maintain soil fertility and reduce the risk of pest and disease infestations.
The rotation may involve planting legumes, such as beans and peas, that fix nitrogen in the soil and then rotating to a cereal crop, such as wheat or corn, that utilizes the nitrogen.
Other crops include root vegetables, such as carrots and potatoes, or cover crops, such as clover and ryegrass, that prevent soil erosion and build soil organic matter.
Incorporating cannabis into crop rotation is a new concept. However, it can bring several benefits to farmers like you looking to try something new.
Cannabis complements the growth patterns of some crops, which means it can be grown alongside other crops without competing for essential resources, helping farmers optimize their land use and increase their yield per acre.
Plus, rotating cannabis with other crops can help break disease and pest cycles. As discussed above, cannabis is a natural pest repellent and is also found to improve soil health.
Promoting Biodiversity on the Farm
Biodiversity refers to the variety of living organisms, from microbes to plants and animals, that inhabit a given ecosystem. In sustainable farming, biodiversity is crucial because it supports a healthy and resilient agricultural system.
By promoting biodiversity on their farms, farmers can enhance the productivity and sustainability of their agricultural systems as they’re better able to withstand external stressors.
Cannabis can also contribute to biodiversity by attracting beneficial insects to the farm. These insects can help to pollinate the cannabis and other crops. For example, ladybugs, lacewings, and parasitic wasps are all beneficial insects that can help control pests like aphids and spider mites.
Some examples of companion plants that can be grown alongside cannabis include:
Marigolds – known for their ability to repel pests like aphids, whiteflies, and nematodes. They also attract beneficial insects like ladybugs and lacewings.
Clover – a nitrogen-fixing plant that can help to improve soil health and provide habitat for pollinators. It’s also a good cover crop to prevent soil erosion and improve soil structure.
Nasturtiums – a plant that repels pests like aphids and whiteflies. They also attract beneficial insects like bees and butterflies.
Sunflower – a great companion plant for cannabis because it attracts pollinators and provides shade for the cannabis plants.
Basil – a popular, fragrant herb that can help to repel pests like mosquitoes and attract beneficial insects like bees and butterflies.
7 Practical Tips and A Look Ahead
Cannabis incorporation into your crop rotations is a smart move. However, you should follow some basic protocols like:
- Understand Legalities: Ensure you comply with local and federal regulations regarding cannabis cultivation. Licensing, permits, and crop insurance are all crucial.
- Start Small: Start with a small plot if you’re new to cannabis cultivation. It’s better to expand as you gain experience.
- Choose the Right Strain: Select cannabis strains suitable for your climate and soil conditions. Some strains are more resistant to pests and diseases, which can benefit overall crop health.
- Soil Health: Cannabis thrives in well-draining, nutrient-rich soil. You may cover crops to improve soil structure and fertility during non-cannabis growing seasons.
- Water Needs: Cannabis has specific water needs. Ensure a proper irrigation system to avoid overwatering or underwatering, and consider collecting rainwater for a more sustainable water source.
- Harvest Timing: Understand the ideal harvest time for your cannabis strains. Harvesting too early or too late can impact the quality of your crop.
- Drying and Curing: Lastly, dry and cure your cannabis properly to achieve the desired potency, flavour, and aroma.
While you’re at it remember, each farm is unique, so adapt these tips to fit your specific conditions and goals.
Happy farming!
