Alfalfa Food Plots for White-tailed Deer

Alfalfa Food Plots

Food plots are commonly used by deer managers to provide supplemental forage for white-tailed deer. Most hunters and deer managers like to plant forage species that are easy to maintain. However, a little extra work is usually worth it. Alfalfa food plots for deer fall into that category. Besides, nothing worth having comes easy. And, a little extra work can pay off big, especially if you consider establishing alfalfa (Medicago sativa L.) as a forage plant for deer on your property.

Alfalfa is an excellent spring, summer, and early fall food plot choice for white-tailed deer. Alfalfa is a cool-season perennial legume that contains 16% to 26% of highly digestible protein. Whitetail will flock to a well-established alfalfa field. In addition, this perennial can survive for 5 to 10 years if managed properly. It’s a good food source for deer for those willing to put in the effort.

Alfalfa Food Plots are Tough

Established alfalfa plants have taproots that extend 4-5 feet deep in the soil. As a result, this forage species makes for a very drought tolerant food plot for deer and other wildlife. And what’s better than a drought tolerant food plot? Well, how about a highly productive food plot that is capable of fixing its own nitrogen? Yep, there is a lot to like about alfalfa.

This forage plant is a legume and does not need the application of nitrogen fertilizer. Like other legumes, it makes its own. Established alfalfa is tough. However, it’s not always easy to establish, Alfalfa is a highly effective forage plant for fall and winter food plots, but spring planting is recommended. After the first year, alfalfa serves as a dependable spring food plot for whitetail.

Alfalfa has many attributes that make it a great choice for forage plots. However, some deer managers find it difficult to establish and maintain. Alfalfa is not a plant where one can just disk, throw, and grow with the addition of a little fertilizer like oats or wheat.

Alfalfa has low tolerance for moisture and soil acidity. In addition, it performs best on well-drained soils (loam to sandy loam) with a pH between 6.5 and 7.5. And even though alfalfa is capable of fixing its own nitrogen, plots usually require annual applications of other soil nutrients. These often include macro- and micronutrients such as phosphorous, potassium, sulfur, and even boron. Additionally, alfalfa must be inoculated with Rhizobia bacteria (Type A) prior to planting.

Managing Alfalfa Plots

New alfalfa food plots for deer and other animals must be managed. Heavy competition from weeds can will put a lid on recently-planted and poor (thin) stands of alfalfa. In addition, white-tailed deer can over-browse alfalfa plots. This is especially true before plant establishment and/or early in the plant’s growing season. However, proper management by the manager ensures the alfalfa planting is successful.

First and foremast, proper seedbed preparation is important. This is true for any food plot, but especially when trying to start alfalfa. Control competitive plant species through chemical or mechanical treatments. In addition, ensure that white-tailed deer are not present at a high density. If so, overuse of the food plot by deer could be an issue early on. Options include reducing the deer population or excluding animals from the food plot until it is established. Electric fencing and tall net-wire fencing will do the job.

Alfalfa for Food Plots

Believe it or not, there are currently over 220 varieties of alfalfa! Alfalfa varieties are rated for fall dormancy and winter hardiness. These factors should be considered based on the latitude of your property. When evaluating alfalfa, pay attention to hardiness and dormancy. Fall dormancy relates to how soon an alfalfa variety stops growing in the fall and how early it begins growing again in the spring. Winter hardiness pertains to how well an alfalfa variety will survive over multiple winters.

Once established, the dormancy and winter hardiness ratings determine the length of the variety’s annual growing season and the life of the alfalfa food plot. The best way to choose alfalfa varieties that are suitable in your area is to talk directly with local seed dealers, agricultural extension agents, and wildlife biologists.

Planting Alfalfa Food Plots for Deer

Alfalfa food plots can generally be planted in April or September-October each year. Spring is preferred. Timing depends on latitude and the variety of alfalfa. Alfalfa can grow 2 to 3 feet in height and produce an astounding 3 to 5 tons of high quality forage per acre! It is a cool season species that will start growing in late-March, persist through the summer, and grows throughout October at southern latitudes.

Alfalfa planting rates vary by variety, but usually run around 15 to 20 pounds per acre. Seed costs for alfalfa plantings range from $60-80 per acre. Alfalfa food plots for deer and other animals requires more costs and effort up front than other plots. However, the reward is a high quality forage that benefits your whitetail and deer management program year after year. Alfalfa plots are a good investment for properties with suitable soils.

The Movement of Whitetail Bucks

Every animal, including white-tailed deer, has an area that they call home. In the wildlife world this area is know as home range. The home range of an individual white-tailed buck, however, varies by season. One would expect that the range of a buck would be fairly stable for much of the year, only to increase in size during the breeding season. This increase in range would be the result of the buck’s behavior and increased movement in his search for receptive does. Although thought to be true, does this phenomenon really happen?

Summer is a good time to be a whitetail buck. Not only do male deer get along, but packs of bucks run together in beloved bachelor groups. Hunters and managers alike get a thrill every time they stumble across a fraternity of whitetail. These observations often serve as confirmation that their harvest stategies or deer management programs are effective. We all like to see healthy bucks. Bachelor groups, by the way, can range in size from 2 to 3 deer up to as many as 28 bucks. At least that is the largest number of free-ranging bucks seen together that anyone has ever reported to me.

It is also during the summer that bucks move around a fair amount, but not as much as during the rut. As summer draws to an end, most bucks become less mobile and highly patternable. It is the time immediately after bucks shed their velvet that they become aggressive towards one another and a bit more territorial. By September, hunters at southern latitudes will start to see individual bucks visiting the same feeding areas again and again.

This is especially true for hunters that use game cameras to monitor their feeders, ag fields, and food plots. That is, if there is a spring food plot left to monitor after summer and the local deer have their way with it. During much of the summer, bucks will be picked up here and there on game cameras as they travel around the countryside eating where they may, but after developing hardened antlers it is a whole other story. A buck’s antlers are quite tender while covered in velvet. Not the case once they harden.

Changes is hormone levels in addition to physical changes cause bachelor groups to disband. Bucks flying solo will hone in on stable food sources and form a core area until the rut. During the breeding season, whitetail bucks will, for the most part, expand upon their summer range in search of receptive does. Following the rut, bucks will sink back into their core range.

A buck’s seasonal range increases and decreases based on many factors, but bucks fall into a very repetitive routine between the loss of velvet and the start of the rut. Year-in and year-out, white-tailed deer have a fairly predictable home range that will vary between seasons. Much a whitetail buck’s movements are determined by environmental conditions, food availability, and the breeding season. Whether you are a hunter looking to bag a buck this year or a landowner interested in better deer management, pay attention to the areas that whitetail bucks are using and use it to your advantage.

Spotlight Surveys for White-tailed Deer

The importance of estimating a white-tailed deer herd on an annual basis is critical to any ranch interested in deer management. And although several survey types (methods) should be combined to get the most accurate deer population estimate, I prefer to use spotlight surveys to estimate the deer density on any given ranch. With that said, deer spotlight surveys on properties less than 400 acres in size become less reliable. The smaller the ranch, the more I shy away from using spotlight routes. This is not necessarily because the methodology is bad, but because smaller ranches have fewer roads. Fewer roads equates to shorter spotlight survey routes and data that is less reliable.

But it can get even worse, especially if a property owner tries to create more survey length by looping around in a smaller area. Surveying smaller properties increases the potential of counting deer in one area, then looping around and counting them again in another area. To accurately estimate deer density on any ranch, animals can not be repeatedly counted along the route. I refer to the importance of maintaining and recording data on individual deer herds all of the time, but I’ve never mentioned exactly how a spotlight survey should be conducted. We are going to fix that today. If you are interested in getting the best white-tailed deer density estimate possible, then this is how a spotlight survey should be performed.

Fawns are Twins, But Not Identical

Most people, including me, find any variation in white-tailed deer quite intriguing. In fact, most hunters and deer managers even select for certain characteristics, specifically when in comes to antler configuration. Depending on the individual hunter, they may look to harvest bucks with really wide antler spreads, bucks with numerous points, bucks with non-typical antlers, or very old deer. Color is also selected for by hunters because if the opportunity presents itself, many hunters will not hesitate to harvest a uniquely-colored deer. However, I do not know of any individual or ranch that manages for deer color.

Although there is some amount of color variation between all living whitetail, we all know what a white-tailed deer should look like. They are usually some variation of brown on top with white under the body, on the throat-patch, around the eyes and nose, and let’s not forget the white under the tail. After all, they are white-tailed. We know how a deer should look, but this is exactly why any color variation, even minor, sticks out. We, as predators, pick up on any abnormality or weakness exhibited by deer. This is why we do not see many white albino deer or black melanistic deer–they occur rarely, and when they do, these deer are removed from the population by hunters or natural predators. That is unless these deer are found in protected areas, such as urban or suburban areas.

Such is the case with the city of Austin, Texas. Melanistic deer naturally occur in this area and show up again year after year. Black-colored deer occur throughout the United States in very small numbers, but apparently the gene pool for melanistic deer is well-stocked in Austin. From a genetic standpoint, this makes sense. The “normal” color observed in deer is the result of dominant genes. Any variation in that color is caused by abnormal, or recessive genes. Just as many deer management programs spare certain bucks to concentrate genes for specific traits, the melanistic deer in Austin, Texas, have been spared because they live in a developed area.

This has allowed the very recessive genes for black hair, at least in white-tailed deer, to be passed on in a “protected” area with little to no predators. And although these genes are concentrated, the genes are recessive and do exist in an open population. So not every deer is melanistic, but melanistic deer can occur when melanistic deer, or deer that carry melanstic genes (but look normal), breed. The take home message as it relates to deer management on your property is that certain genes–even rare ones–can be increased within a population if managed and protected.

Antler Growth in White-tailed Deer

Testosterone levels control just about everything on a white-tailed buck, including antler growth and development. During this time of year, a buck’s testosterone level is quite low, but those levels will begin to increase as summer comes to an end and the fall season rolls around. Testosterone levels will peak just prior to the rut. It is during that time when bucks become very aggressive towards one another, establish breeding dominance, and prepare for the rut. That time of year can be rough on a whitetail buck.

When I received this photo of three white-tailed bucks in my inbox a couple weeks ago, the sender wrote that the deer on the left and the right (in the photo above) were bucks. I zoomed in for a closer look and noticed that not only two, but that in fact all three of the deer were bucks. And the photo makes sense because whitetail bucks have low testosterone during the spring and summer, and they can stand to be around one another.

This is the reason for spring and summer bachelor groups. Furthermore, does tend to be more solitary leading up to fawning season. Does will not associate with bucks, or other does for that matter, until several days to a couple of weeks after the fawns are born.

There are other reasons, besides low testosterone, why bucks will not fight very much during the spring and summer. It is because their antlers are quite fragile. Growing antler material is basically is pre-formed cartilage, so trying to fight each other while in velvet would be like butting their noses together. It would not feel good and there would be a lot of blood shed.

Bucks, even with velvet-covered antlers, still have minor disagreements. They, however, settle these spats by standing on their hind legs and using their front legs to kick in the same manner that we often see does fight. Bucks fight only in this particular manner when in velvet during the antler growing period. During the remainder of the year bucks may fight in this manner but often choose head-to-head combat.

Whitetail bucks change drastically between spring-summer and the fall season. With rising testosterone levels, antlers complete their growth and bucks are spurred to shed velvet and rub on trees and shrubs. This rubbing activity and increase in testosterone creates noticeable changes in a buck’s body. During the spring and summer bucks have doe-like necks. With decreased hormones and no antlers up top — and no one willing to fight —their neck muscles shrink in size.

However, increased testosterone and antler rubbing soon condition a buck’s front-end and neck into a fighting machine, typical of what most hunters expect to see during the hunting season. This conditioning helps individual bucks compete for does and helps them submit does, as well. After all, during the rut hunters often see does running away from the bucks!

Whitetail bucks change drastically between the breeding season and the “off season.” These physical changes, in terms of their body and antler growth, are related to an individual buck’s testosterone level. Bucks have low levels of testosterone during the antler growing period and high levels of testosterone just before and during the breeding season.

These physical changes can make it difficult for most hunters to estimate the age of a deer on the hoof during the summer months, but whitetail bucks quickly “whip themselves into shape” for the big show as fall approaches.
