Corn vs. Soybeans for Deer: A Food Plot Guide for Hunters & Land Managers

As a seasoned outdoor writer and hunter with over a decade spent exploring and writing about the American landscape, I’m frequently asked: do deer like soybeans or corn better? It’s a question that goes to the heart of successful deer management, especially when it comes to establishing effective food plots. The answer, as with most things in nature, isn’t simple. While both corn and soybeans are highly attractive to whitetail deer, understanding their nutritional value, seasonal preferences, and planting considerations is crucial for maximizing your food plot’s appeal. This guide will delve into the specifics, helping you determine whether corn food plots or soybean fields are the best choice for your land, and even explore options like field corn seed for deer and the use of Roundup Ready corn for food plots.

Understanding Deer Nutritional Needs

Before diving into the specifics of corn and soybeans, it’s important to understand what deer are looking for in their diet. Deer are browsers, meaning they prefer to eat leaves, twigs, fruits, and nuts. However, they’ll readily consume agricultural crops, especially when natural forage is scarce. Their dietary needs change throughout the year. In spring and summer, they focus on high-protein foods for antler growth and reproduction. Fall and winter demand high-energy foods to build fat reserves for the cold months. According to the National Park Service, a healthy deer diet is diverse and depends heavily on seasonal availability.

The Nutritional Breakdown: Soybeans vs. Corn

Soybeans are nutritional powerhouses, boasting a protein content of around 36-56% and a digestible energy content of around 800-900 kcal/lb. This makes them incredibly attractive to deer during the crucial summer months when they need protein for antler development and lactation. Corn, on the other hand, is primarily a carbohydrate source, with around 8-10% protein and a digestible energy content of around 1400-1600 kcal/lb. While lower in protein, corn provides a significant energy boost, making it a favorite during the fall and winter when deer are preparing for and enduring cold weather. REI’s Expert Advice section highlights the importance of providing both protein and energy sources throughout the year.

Do Deer Eat Corn Plants? A Seasonal Perspective

The question of do deer eat corn plants isn’t just about the mature grain. Deer will browse on corn at various stages of growth. Young corn shoots and leaves are highly palatable and can be a significant food source in the spring. However, as the corn matures and the stalks become tougher, deer preference shifts towards the kernels. They’ll often “pull” corn plants down to access the ears, causing significant damage if the plot isn’t properly protected. This is where considering field corn seed for deer comes into play – certain varieties are bred for increased stalk strength and ear height, making them less susceptible to this type of damage.

Corn Varieties for Deer Food Plots

Not all corn is created equal when it comes to attracting deer. Here’s a quick look at some popular options:

• Traditional Field Corn: Widely available and relatively inexpensive, but can be more susceptible to lodging (falling over).
• Forage Corn: Bred for increased leaf production, providing more browse for deer.
• Grain Corn: Focuses on ear size and kernel production, offering a concentrated energy source.
• Roundup Ready Corn for food plots: Genetically modified to tolerate glyphosate herbicides, simplifying weed control.

The use of Roundup Ready corn for food plots is a common practice, allowing for easier management and higher yields. However, it’s important to be aware of the potential environmental concerns associated with herbicide use and follow all label instructions carefully. The USDA Forest Service offers resources on responsible land management practices.

Soybeans: The Summer Protein Powerhouse

Soybeans are arguably the most popular food plot choice for attracting deer, particularly during the summer months. Their high protein content supports antler growth and fawn development. Deer will readily consume soybean leaves, stems, and pods, and will continue to forage on the beans themselves as they mature. Soybeans also offer the benefit of being relatively easy to establish and maintain. However, they are susceptible to deer browsing, especially when young, and may require protection with fencing or repellents.

Soybean Varieties for Deer

Similar to corn, different soybean varieties offer different benefits:

• Traditional Soybeans: Reliable and widely available.
• Antler Beans: Specifically bred for increased attraction and palatability to deer.
• LabLab: A legume similar to soybeans, offering high protein and good browse potential.

So, Do Deer Prefer Soybeans or Corn?

Ultimately, deer don’t necessarily have a preference – they’ll eat what’s most readily available and meets their current nutritional needs. However, studies and observations suggest that deer generally exhibit a stronger initial attraction to soybeans, especially during the summer months. This is likely due to the higher protein content. As fall approaches and temperatures drop, their preference shifts towards the high-energy carbohydrates found in corn.

I’ve found that a successful strategy is to plant a mix of both corn and soybeans, creating a food plot that provides year-round nutrition. A common approach is to plant soybeans in the spring for summer protein and then overseed with corn in late summer for fall and winter energy. This ensures a consistent food source throughout the entire deer season.

Food Plot Planning Checklist

1. Soil Testing: Essential for determining soil pH and nutrient levels.
2. Seed Selection: Choose varieties appropriate for your region and deer’s nutritional needs.
3. Plot Preparation: Clear vegetation, till the soil, and amend with lime and fertilizer as needed.
4. Planting: Follow recommended planting dates and seeding rates.
5. Weed Control: Manage weeds to prevent competition with your food plot.
6. Protection: Consider fencing or repellents to protect young plants from browsing.
7. Maintenance: Monitor the plot for pests and diseases and address any issues promptly.

Beyond Corn and Soybeans: Expanding Your Food Plot Options

While corn and soybeans are excellent choices, don’t limit yourself. Consider incorporating other attractive food plot options, such as:

• Clover: Provides a long-lasting, high-protein food source.
• Brassicas: Become sweeter and more palatable after a frost, offering a late-season energy boost.
• Alfalfa: A highly nutritious legume that provides both protein and energy.

Leave No Trace Principles in Food Plot Management

Remember, responsible land management goes hand-in-hand with attracting deer. Always practice Leave No Trace principles (leavenotrace.org) when establishing and maintaining your food plots. This includes minimizing soil disturbance, avoiding the use of harmful chemicals, and properly disposing of any waste materials. Protecting the environment is crucial for ensuring the long-term health of your land and the deer population it supports.

By carefully considering the nutritional needs of deer, the benefits of different corn and soybean varieties, and the principles of responsible land management, you can create food plots that attract and sustain a healthy deer population for years to come. Understanding whether do deer like soybeans or corn better is just the first step – the real key is providing a diverse and consistent food source that meets their needs throughout the entire year.
