Corn is an essential crop globally, especially in the United States, where it serves as a staple for food, livestock feed, and biofuel production. For farmers, distributors, and traders, one of the most critical aspects to understand is how much a bushel of shelled corn weighs.
A bushel is a unit of volume, often used to measure agricultural products, including corn. However, the weight of a bushel of shelled corn can vary significantly depending on several factors such as the moisture content, type of corn, and even how it’s stored.
This article provides a comprehensive breakdown of how much a bushel of shelled corn weighs, covering various types of shelled corn, and the factors that influence its weight. By the end of this article, you will have a deeper understanding of how the weight of shelled corn affects agricultural operations and why this measurement is crucial for pricing, storage, and transportation.
What Is A Bushel of Shelled Corn?
A bushel of shelled corn refers to the quantity of corn kernels after they have been removed from the cob. The unit “bushel” measures volume, with a standard bushel defined as 2,150.42 cubic inches or 35.24 liters. The bushel is widely used in the agricultural industry to measure bulk products, including shelled corn, and is particularly important when it comes to trading, pricing, and transport.
The weight of a bushel of shelled corn can vary greatly, primarily due to moisture content. When corn is harvested, it typically contains a certain amount of water, which contributes to its overall weight. The standard moisture content for corn used to determine the weight of a bushel is 15.5%, at which point the weight of a bushel of shelled corn is around 56 pounds (25.4 kg). However, if the moisture content increases or decreases, the weight of the bushel will change accordingly. Wet corn, for instance, weighs more, while drier corn weighs less.
Types of Bushel of Shelled Corn
There are different types of shelled corn, and each has unique characteristics that can affect the weight of a bushel. These types are grown for specific purposes, and their weight can vary depending on kernel size, moisture content, and intended use. Let’s explore the types of shelled corn and how they differ in terms of weight:
- Field Corn: This is the most common type of corn used for agricultural and industrial purposes. Field corn has large, dense kernels, which result in a heavier bushel compared to other types of corn. It’s primarily used for animal feed, biofuels (such as ethanol), and processed food products.
- Sweet Corn: Unlike field corn, sweet corn is typically grown for human consumption and tends to have smaller kernels. When shelled, sweet corn weighs less than field corn due to its smaller kernel size. It’s often used fresh, canned, or frozen.
- Popcorn: Popcorn kernels are small, but they are denser and more compact than the kernels of field corn. This compactness leads to a bushel of popcorn weighing more than the equivalent volume of sweet corn. Popcorn is mainly used for snack foods.
- Flint Corn: Flint corn, also known as Indian corn, has hard, dense kernels and is often used for decorative purposes or in traditional recipes. It’s heavier than sweet corn but lighter than field corn due to its smaller kernel size and higher density.
How Much Does A Bushel of Shelled Corn Weigh?
The standard weight for a bushel of shelled corn, at the typical moisture content of 15.5%, is about 56 pounds (25.4 kg). However, the weight can change based on various factors, particularly moisture content.
- Moisture Content: Corn with higher moisture content weighs more because water adds weight. For example, wet corn with a moisture content of 20% may weigh about 58 pounds (26.3 kg) per bushel. On the other hand, dried corn with lower moisture content can weigh as little as 54 pounds (24.5 kg) per bushel.
- Kernel Size: Larger kernels generally result in a heavier bushel. For instance, field corn tends to be heavier because of its large kernels, while popcorn or sweet corn weighs less due to the smaller, less dense kernels.
- Type of Corn: As mentioned above, different types of corn (field corn, sweet corn, popcorn, flint corn) each have distinct kernel sizes and densities, which affect the overall weight per bushel.

Basics of A Bushel of Shelled Corn Weight
A bushel’s weight is an important metric in agriculture for a number of reasons. Firstly, pricing is directly tied to the weight of corn, as it is often sold by the bushel. The weight is also crucial for transportation; heavier corn may require stronger transportation methods and can increase the cost of shipping. Additionally, understanding the weight is essential for storage: knowing the weight helps determine how much corn can be stored in a specific space, and it’s important for managing stock levels effectively.
Factors Influencing A Bushel of Shelled Corn Weight
The weight of a bushel of shelled corn is influenced by a variety of factors, some of which are directly related to the physical properties of the corn itself, while others are more environmental or related to storage. Understanding these factors is crucial for farmers, traders, and consumers as they impact everything from pricing to storage requirements. Let’s delve into the major factors influencing the weight of a bushel of shelled corn.
1. Moisture Content
Moisture content is perhaps the most significant factor that affects the weight of a bushel of shelled corn. Corn is a biological product, and moisture is naturally present in the kernels after harvest. This moisture adds weight to the corn, and as a result, corn with higher moisture content will weigh more per bushel.
The moisture content of shelled corn typically ranges between 12% to 20%, with 15.5% being the standard moisture content used for measuring weight in trade and farming. When the moisture content is at 15.5%, one bushel of shelled corn weighs approximately 56 pounds (25.4 kg). However, if the moisture content exceeds this, the weight of the bushel will increase. For example, wet corn with a moisture content of 20% can weigh as much as 58 pounds (26.3 kg) per bushel.
On the other hand, corn with lower moisture content, such as corn that has been dried after harvest, will weigh less. For example, corn with a moisture content below 15.5%, such as dried corn with 12% moisture, could weigh around 54 pounds (24.5 kg) per bushel. Thus, moisture content is crucial to accurately determining the weight of a bushel of shelled corn, and it also affects pricing and storage needs, as wet corn may require special handling and faster turnover.
2. Kernel Size
The size and density of the individual corn kernels play a significant role in the overall weight of the bushel. Larger, denser kernels typically mean a heavier bushel because they occupy more volume and are packed more tightly. These larger kernels are commonly found in varieties such as field corn, which is used for industrial and agricultural purposes. The larger kernels pack more tightly in a bushel container, resulting in a heavier weight.
In contrast, varieties such as sweet corn and popcorn have smaller, less dense kernels. These varieties typically weigh less per bushel than field corn due to the smaller size and lower density of the kernels. However, even though popcorn kernels are smaller, they tend to be denser, meaning they can pack tightly into a bushel, which can sometimes result in a weight similar to or slightly heavier than sweet corn.
The density of kernels is a major factor in determining how much corn fits into a bushel. Larger kernels, with their denser packing, contribute to an increase in the overall bushel weight, while smaller or airier kernels will reduce the total weight.
3. Environmental Factors
The environmental conditions under which corn is grown can also influence its weight. Corn is a sensitive crop, and weather conditions such as rainfall, humidity, and temperature can affect its moisture content and, ultimately, its weight.
Corn grown in wetter climates or regions with high humidity tends to absorb more water during the growing season, resulting in kernels with higher moisture content. This is especially the case when rainfall is abundant during the corn’s growing period. As a result, the corn will weigh more because of the additional moisture present in the kernels.
In contrast, corn grown in regions with drier climates or during a growing season with less rainfall tends to have lower moisture content in its kernels. This results in a lighter bushel, as the water content is lower, and the corn weighs less. Farmers may also regulate moisture levels through irrigation, but they must account for how climate affects overall moisture content and subsequent bushel weight.
Corn grown in high humidity regions can also experience higher water absorption, leading to heavier kernels that may not dry down to the same level as corn grown in drier climates. This difference in growing conditions is one reason why bushel weight can vary depending on the geographic origin of the corn.
4. Storage Conditions
Storage conditions are another important factor influencing the weight of shelled corn. Corn harvested and stored under optimal conditions will retain moisture levels that are appropriate for long-term preservation, while improperly stored corn may experience changes in its moisture content, leading to weight loss or gain.
Long-term storage can affect the weight of corn in two significant ways:
- Moisture Loss: Corn that has been stored for extended periods, particularly if it is not in climate-controlled conditions, can lose moisture. This leads to a decrease in weight because moisture evaporates over time. For example, corn that has been stored improperly may weigh less than it did at harvest if it has dried out.
- Moisture Gain: If corn is stored in a damp or humid environment, it can absorb moisture from the air, leading to an increase in weight. This is a common problem when corn is stored in high humidity or poorly ventilated facilities. The increased moisture can make the corn heavier, but it also makes it more susceptible to spoilage and pests.
Moreover, pest infestations or mold in poorly stored corn can cause further weight fluctuations. Molds or pests may affect the kernels and lead to a loss of weight or reduced quality, making it unsuitable for sale. Proper aeration, temperature control, and monitoring moisture levels during storage are crucial to maintaining the integrity of the bushel’s weight.
Why A Bushel of Shelled Corn Weight Matters
The weight of a bushel of shelled corn is an important metric that influences various aspects of the corn trade, from market pricing and transportation costs to storage and handling. This seemingly simple unit of measurement has far-reaching consequences for farmers, distributors, and consumers alike, impacting their profitability, logistical efficiency, and operational processes. Let’s explore in more detail why the weight of a bushel of shelled corn matters.
1. Market Pricing
In agriculture, weight is one of the primary factors used to determine the value of products, including shelled corn. Farmers and suppliers often rely on the bushel weight to set prices in the market, with heavier corn typically fetching higher prices, especially if the moisture content is higher. Moisture content significantly impacts weight because wet corn weighs more than dry corn, and this added mass can drive up the price of the corn per bushel.
For instance, corn with a higher moisture content—usually over the standard 15.5%—is often considered more valuable in the marketplace because it weighs more per bushel. However, the higher weight can be a double-edged sword. While it may increase the price of the bushel, it can also require additional drying time before the corn can be stored or sold, and it could also impact the long-term storage stability. Traders and buyers take all these factors into account when purchasing shelled corn, making the weight a critical pricing component.
2. Transportation Costs
The weight of a bushel of shelled corn directly impacts transportation logistics. Heavier bushels require more fuel for transportation and necessitate stronger or more durable equipment to carry the load. Shipping corn, especially in bulk quantities, involves significant logistical planning, and transportation costs are a key part of this. A heavier load translates into more fuel consumption and, consequently, higher shipping costs.
For example, when transporting shelled corn in bulk, the weight directly determines how much corn can fit into a given shipment. If the moisture content is higher, the bushel will weigh more, reducing the amount of corn that can be transported in a single load. This can lead to more trips and higher overall transportation costs. Additionally, the type of vehicle used for shipping must be considered. Trucks and containers have weight limits, and heavier corn may require more trips or larger, more expensive equipment to transport.
3. Storage and Handling
Weight plays a crucial role in determining how much corn can be stored in a given space, which affects storage costs. Storage facilities (such as silos, warehouses, or grain elevators) have capacity limitations based on volume and weight. A bushel’s weight affects how efficiently it can be stored and how much space will be required to store a specific quantity of corn.
For example, a warehouse with limited space can store a certain number of bushels depending on their weight. If the weight of the corn increases due to higher moisture content, the available storage capacity decreases. Heavier corn takes up more space because more mass is packed into the same volume. This may lead to increased storage fees if additional facilities are required to accommodate the extra weight. In some cases, corn with excessive moisture must be dried before being stored, adding further costs and operational challenges.
The weight of shelled corn also impacts handling procedures. Heavier loads require more labor and more robust equipment to move. For example, machinery such as forklifts and conveyors used to transport corn around storage facilities must be capable of handling the increased weight. Heavier corn may also require special handling during transportation, as it may be more prone to damage or degradation if mishandled.
How Much Does A Bushel of Shelled Corn Cost?
The price of a bushel of shelled corn varies considerably depending on several factors, including the type of corn, moisture content, region, and market conditions.
