Illinois sits at the heart of the Corn Belt, yet savvy growers diversify with alternative cash crops. If you’re looking for the best cash crops to grow in illinois, you need to consider soil types, climate patterns, and market demand. This guide breaks down the top options that actually make money in the Prairie State.
Whether you own 40 acres or manage a larger farm, choosing the right crop is critical. Illinois offers a long growing season, rich soil, and access to major transportation routes. Let’s look at what works best.
Corn And Soybeans: The Illinois Standards
Corn and soybeans dominate Illinois farmland for good reason. They are reliable, have established markets, and benefit from decades of research. But they aren’t the only game in town.
Field Corn For Grain
Field corn is the most planted crop in Illinois. It thrives in the state’s deep, fertile soils. You can sell it for livestock feed, ethanol, or industrial uses. The average yield is around 200 bushels per acre.
- Requires warm soil (50°F at 4 inches deep)
- Needs 20-25 inches of water during growing season
- Best planted in April or early May
- Harvest typically starts in October
Soybeans For Protein And Oil
Soybeans are the second most common crop. They fix nitrogen in the soil, reducing fertilizer costs. Illinois farmers average about 60 bushels per acre. The crop is exported worldwide.
- Plant in late April through May
- Requires less nitrogen than corn
- Harvest from late September to October
- Works well in rotation with corn
