What Is a Bushel of Soybeans?
A bushel is a standard unit of measurement used in agriculture to quantify dry goods, including grains, beans, and other commodities. Though a bushel measures volume rather than weight, the weight of a bushel is standardized for each type of commodity to maintain consistency in trade and pricing. For soybeans, one bushel is equivalent to 60 pounds (27.22 kg) at 13% moisture content.
Key Points:
- Volume vs. Weight: While a bushel measures volume, the weight of a bushel is defined for consistency. For soybeans, this means a bushel contains 60 pounds of soybeans at 13% moisture.
- Moisture Content: Moisture content is a key factor in determining the weight of a bushel. Soybeans with higher moisture content will weigh more, while drier soybeans weigh less. This variation can impact yield calculations and pricing.
Additionally, the test weight is another important consideration. Test weight refers to the weight of a bushel relative to its volume. Soybeans with a higher test weight are denser, and denser beans are usually of higher quality because they have more protein and oil content.
How Much Does a Bushel of Soybeans Weigh?
The industry-standard weight of a bushel of soybeans is 60 pounds (27.22 kg) at 13% moisture content. However, this weight can vary depending on several factors, primarily moisture content, which we’ll discuss in more detail below.
Standard Weight:
- 60 pounds (27.22 kg) is the standard weight for soybeans when at 13% moisture.
Variations Based on Moisture Content:
Soybeans are a natural product, and their moisture content can fluctuate depending on the timing of the harvest, weather conditions, and storage methods. Soybeans harvested at higher moisture levels will weigh more than those harvested at lower moisture levels.
- Low Moisture Soybeans (9%): When soybeans have a moisture content of around 9%, they will weigh slightly less than the standard 60 pounds per bushel due to the reduced water content. This could result in a weight of 59 pounds (26.76 kg) or even less.
- High Moisture Soybeans (15%): Soybeans harvested with higher moisture, around 15%, will weigh more than the standard 60 pounds. These soybeans can weigh as much as 62 pounds (28.12 kg) per bushel or more. Higher moisture content can also affect storage and transportation since wetter soybeans are prone to spoilage.
Impact of Moisture Content:
Moisture content plays a significant role in the weight of soybeans. A 1% increase in moisture can add 0.5 to 1 pound (0.23 to 0.45 kg) per bushel. This means that managing moisture levels during harvest and storage is essential for maintaining consistent weight, quality, and value.

Things That Impact a Bushel of Soybeans’ Weight
Several factors contribute to the overall weight of a bushel of soybeans. These include environmental conditions, seed characteristics, and post-harvest handling. Understanding these factors is essential for farmers, traders, and those involved in the agricultural supply chain.
1. Moisture Content:
Moisture content is the single most important factor affecting soybean weight. Soybeans with higher moisture will be heavier, and lower moisture soybeans will weigh less. Moisture is influenced by the timing of the harvest and the weather conditions during the growing season. Soybeans are usually harvested when they reach 13% moisture, but factors like drought or excessive rainfall can impact moisture levels.
- Impact: A 1% change in moisture content can change the weight of a bushel by 0.5 to 1 pound (0.23–0.45 kg).
2. Seed Size and Density:
Soybean seed size can vary depending on the variety and growing conditions. Larger seeds tend to be denser, and denser seeds fill a bushel more effectively, resulting in a heavier weight. Seed size is also influenced by factors such as soil fertility, water availability, and planting density.
- Impact: Larger, denser seeds increase the test weight, making the bushel heavier.
3. Weather and Environmental Factors:
The growing season’s weather has a substantial impact on the overall weight of soybeans. Factors like rainfall, temperature, and sunlight during the growing season affect seed development, moisture levels, and ultimately, weight. Excessive rainfall can result in higher moisture content, making the soybeans heavier. Conversely, drought conditions tend to produce drier, lighter beans.
- Impact: Wet weather can lead to higher moisture levels, increasing the weight of soybeans during harvest.
4. Storage and Handling:
Post-harvest conditions, including storage and handling, also play a role in the weight of a bushel. Soybeans left in improper storage conditions may lose moisture over time, causing their weight to decrease. Moisture loss can be prevented through proper ventilation and climate control in storage facilities.
- Impact: Soybeans stored in high humidity or improperly ventilated areas can lose weight by 5% due to moisture evaporation.
