What Is Industrial Hemp?

Industrial hemp is an adaptable and multi-purpose crop that has gained momentum in the Upper Midwest as a sustainable option for both oilseed and bast fiber production. With its ability to fit into diverse cropping systems and growing demand for its derived products, hemp offers farmers in the region an opportunity to capitalize on a high-potential crop while enhancing soil health and diversifying income streams.

​

From an agronomic perspective, hemp is a robust, warm-season crop that performs well in the temperate climates of the Upper Midwest. Its ability to grow quickly and establish a dense canopy makes it highly competitive against weeds, reducing the need for chemical inputs. Hemp thrives in well-drained, nutrient-rich soils with pH levels between 6.0 and 7.5 and requires moderate water and fertility inputs, making it suitable for rotation with crops like corn, soybeans, and small grains.

Hemp for Oilseed Production

​

Hemp seeds, often referred to as hemp hearts when hulled, are a nutrient-dense oilseed valued for their high levels of essential fatty acids, particularly omega-3 and omega-6. Hemp oil, cold-pressed from the seeds, is widely used in health food, cosmetics, and industrial applications. The byproduct of oil extraction, hemp seed cake, is a protein-rich feed ingredient that can add value to livestock operations.

​

For farmers, the oilseed market for hemp represents a growing opportunity driven by consumer demand for plant-based nutrition and sustainable products. Hemp seeds mature in approximately 100–120 days, depending on the variety and planting conditions, and harvesting can be easily integrated into existing equipment with minor modifications.

Hemp for Bast Fiber

​

The bast fibers from hemp stalks are among the strongest natural fibers available, making them highly sought after for a range of applications, including textiles, bioplastics, composites, and construction materials like hempcrete. The global push for sustainable materials has sparked renewed interest in hemp fiber markets, offering farmers a reliable secondary income stream.

​

To optimize fiber quality, agronomic practices such as selecting fiber-specific varieties, planting at higher densities, and precise harvesting techniques are critical. Hemp for bast fiber can be grown and harvested within 90–120 days, with retting and decortication processes tailored to end-use specifications. The crop’s ability to improve soil structure through deep taproots and organic matter return further enhances its appeal as a rotation option.
