How to Start Sorghum Farming in the USA: A Step-By-Step Production Guide

Sorghum, a versatile and hardy grain crop, has been growing in popularity as a sustainable and profitable crop in the United States. Not only is it drought-tolerant and adaptable to various soil types, but sorghum is also used for multiple purposes, including food, animal feed, and biofuels. Below we learn how to start sorghum farming, sorghum benefits and uses, and a step-by-step guide to starting a sorghum farm in the USA.

Understanding Uses

Sorghum is a cereal grain that originates from Africa. It’s a grass, thus it can grow in many conditions. Sorghum is primarily used for three main purposes:

Human consumption: Sorghum flour, a gluten-free grain, is used to manufacture foods like bread and porridge.
Animal feed: Sorghum is an important feed grain for livestock, providing valuable energy and protein.
Biofuels: The high starch content in sorghum makes it a suitable crop for producing ethanol, an alternative to fossil fuels.

Choosing the Right Variety

Grain sorghum: These varieties are cultivated primarily for their seeds and used for human consumption, animal feed, and biofuels.
Sweet sorghum: This type of sorghum is grown for its stalks, which contain high levels of sugar, making it ideal for producing syrup, molasses, and biofuels.
Forage sorghum: This variety is used for silage or hay, providing a valuable source of fodder for livestock.

When selecting a sorghum variety, consider your intended use, climate, and soil type to ensure optimal growth and yield.

Soil Preparation and Fertility Management

Sorghum is known for its adaptability and can be grown in various soil types. However, it thrives best in well-draining, loamy soils with a pH between 6.0 and 7.5. To prepare your soil for sorghum farming, follow these steps:

Soil testing: Determine the soil’s nutritional levels, pH, and organic matter by doing a soil test. You’ll be able to apply fertiliser and soil additives with more confidence after reading this.
Tillage: Sorghum requires a well-prepared seedbed. Perform primary tillage to break up compacted soil, followed by secondary tillage to create a fine, even seedbed.
Fertilization: Based on your soil test results, apply appropriate fertilizers to ensure adequate nutrient availability. Sorghum typically requires nitrogen, phosphorus, and potassium for optimal growth.

Planting

Planting time is crucial for successful sorghum farming. In the United States, sorghum is typically planted between mid-April and mid-June. However, this can vary based on your location and the sorghum variety you choose. Follow these guidelines for planting sorghum:

Seed selection: Choose high-quality, certified seeds with good germination rates and resistance to common pests and diseases.
Seeding rate: Plant sorghum seeds at a rate of 5-7 pounds per acre. This may vary depending on the variety and intended use, so consult seed packaging or local extension services for specific recommendations.
Seeding depth: Plant seeds at a depth of 1-1.5 inches in moist soil. If soil moisture is low, you can plant up to 2 inches deep to ensure adequate seed-soil contact.
Row spacing: Space rows 20-30 inches apart to allow for sufficient sunlight and air circulation. Some farmers opt for narrower rows to increase plant density and potentially improve yields, but this can also increase the risk of disease and pest pressure.

Water and Irrigation

Sorghum is drought-tolerant and requires less water than other grain crops like corn. However, proper water management is still essential for maximizing yields. To maintain optimal soil moisture:

Monitor rainfall: Keep track of rainfall levels in your area and adjust irrigation accordingly. Sorghum requires about 18-24 inches of water throughout its growing season, with the most critical periods being germination, flowering, and grain filling.
Irrigation methods: Utilize efficient irrigation methods like drip or center-pivot systems to conserve water and reduce evaporation losses. Avoid over-watering, as excess moisture can lead to fungal diseases and reduced yields.

Weed, Pest, and Diseases

Crop rotation: Rotate sorghum with other crops to disrupt pest and disease life cycles and reduce weed pressure.
Timely cultivation: Perform timely cultivation to control weeds before they compete with sorghum plants for nutrients and water.
Scouting: Regularly scout your fields to identify potential pest and disease issues early. Early detection allows for timely intervention and minimizes crop damage.
Integrated Pest Management (IPM): Utilize IPM strategies, such as biological controls, resistant varieties, and targeted pesticide applications, to manage pests and diseases while minimizing the impact on beneficial organisms and the environment.

Nutrient Management

To ensure optimal sorghum growth and development, monitor nutrient levels and address any deficiencies throughout the growing season. Consider the following nutrient management practices:

Split nitrogen application: Apply nitrogen in multiple stages, such as at planting and during the vegetative growth phase, to reduce leaching and ensure adequate nitrogen supply for the entire growing season.
Foliar fertilization: Apply foliar fertilizers containing essential micronutrients, such as zinc, iron, and manganese, to address specific deficiencies and improve overall plant health.
Soil and tissue testing: Periodically conduct soil and plant tissue tests to monitor nutrient levels and make necessary adjustments to your fertilization plan.

Harvesting

Grain moisture: Harvest sorghum when grain moisture is between 18% and 25% to minimize losses during threshing and drying.
Plant appearance: Look for signs of crop maturity, such as a change in grain color from green to golden brown and the drying of leaves and stalks.
Test weight: Monitor the test weight of your grain, aiming for a minimum of 56 pounds per bushel for the best quality and marketability.

Post-Harvesting

Drying: Dry sorghum grains to a 12% to 14% moisture content to prevent mold growth and spoilage during storage.
Cleaning: Clean harvested grain to remove any dirt, chaff, and foreign material.
Storage: Store sorghum in clean, well-ventilated, and moisture-resistant structures to maintain grain quality and prevent spoilage.
