I am one of those people that is a stickler for the truth, I am forever searching for it in the oft times murky waters of life. It's no surprise then that I am constantly testing something and doing so usually challenges things that many have been lead to believe.
If I am going to stick my neck out because I suspect deception or to disprove a myth I try to use care to make sure my tests are bona fida and with few flaws.
Even at that there will always be those who look upon my information with skepticism so I always encourage landowners to do their own testing and to continue doing so on an ongoing basis as their habitat goals and needs change.
There are some common mistakes that landowners make that often reveal there was indeed no "test" at all and just a perceived thought that something appeared to be better or worse.
One thing we commonly test for is deer preference or lack of it in various forages or varieties within a species and to do this fairly the test comparisons must be side be side and in multiples so that one is not placed on the outside next to a runway while the other is difficult to reach.
An example is corn and soybean test plots....farmers don't plant one hybrid on this side of the farm on rich black soil and another on a clay knob in the back 40. They pick a level fertile spot and plant identical length rows of each variety, fertilize and spray all the same and then harvest and weigh the crop all at the same time.
I often hear people say "I planted WTI clover and Biologic clover and they were all in the Biologic field!"....That only means that they felt safe in that field not that they preferred a certain type of clover.
Both clovers need to be planted in side by side multiples in BOTH fields and then fields monitored with trail cams and observation of both the clovers (for grazing) and of deer feeding in the fields.
Some folks believe that fertilizing clover with nitrogen in the fall will make a difference so I tested that theory but found no difference in either the appearance, growth or grazing in my test plots.
Deer have core areas where they feel safe and they will not travel far from bedding to feed if they don't have to...they are programed to not waste energy and they less they move the safer they are. It takes an extremely attractive food source such as standing soybeans in late December to actually draw deer from any distance so people would be naive to think that a certain clover, cereal or turnip might cause them to abandon all caution to feed on that food source.
Conduct your tests in multiple areas of your farm or property starting with the areas closest to their bedding areas and normal travel areas. Use stakes or flags to mark the different strips containing the test forage varieties or species.
This pic doesn't show the markers but you can see how I planted multiple strips of in this case BFO, Jerry, BFO, and Jerry oats (the Jerry is the lush green color)
The two left strips were also mixed with rye and peas to give me further comparisons.
There are many variables that affect whitetails during a given year and from year to year yet I often hear people exclaim "I planted wheat one year and barley the next and deer definitely preferred the barley!"
That is an impossible statement to make and there was actually no test whatsoever even done. Factors such as a bountiful acorn crop one year and none the next or soybeans next door one year and corn the next all have dramatic effects on whitetails and their usage of any food source.
The size and location of plots or fields is a huge but usually overlooked factor yet often landowners observe dozens of deer in a 50 acre wheat field and then complain bitterly that deer don't like the oats in their 1/4 plot?
Doe groups like their space and will take advantage of larger fields where they can spread out and in doing so create a visual image that leaves a convincing image implanted in ones mind. The truth is though that if that wheat field was oats, or rye or barley...the same deer would be feeding there.
Test different forages on your property and observe the usage of two test comparisons side by side....not yours against the neighbors place.
Others don't even realize what they are saying when they mix multiple forages together and say "yep...they like A better then B or C"....so that means that B and C must be 2 foot tall in clumps all over the field correct??
Of course such is not the case and it is impossible to test a mix of forages against itself.
Testing with exclusion cages can sometimes be tricky unless the two plants are nearly identical in growth habits. Testing a tall ladino clover against a shorter white clover with cages would prove fruitless because one is naturally taller then the other.
Cereals are the same way because some oats have a taller growth stature, rye grows faster and taller then wheat and so on and so forth.
I observe the plants up close as getting down on my knees and examining the plants for evidence of grazing or lack of it. If deer actually preferred wheat over oats or rye or triticale then the test comparisons would quickly reveal that. In decades of testing however (with the exception of BFO) NEVER, not even ONCE have deer shown any preference to any cereal grain and grazing is across the board equal.
Then of course there are the thought trains that some "buck on a bag" seed has been specially "developed" and has some magical powers so I plant them ALL...side by side in multiple plots on multiple farms all 15- 20 miles apart and ALWAYS the results are the same. Deer eat them all or refuse to touch them all as this pic reveals where all the name brand brassicas were untouched.
People are often under the illusion that mixing lots of "stuff" together will also increase the drawing power but that is rarely the case. It's a simple matter to plant oat, wheat and rye together and then plant strips of each in the center and see if they only eat the "mixed" areas.
Try rye alone, rye and peas, rye peas and oats in the same field and see if it makes any difference at all but you can NOT plant rye in a field by the road and rye and peas in a hidden plot next to a bedding area and expect that to be a fair comparison.
Test drought resistant clovers like Alice and Durana against well known "big buck brand" clovers and you will find out which ones are really the best.
Some things I know to be true in Iowa....
acorns in October, freshly combined corn in November and standing soybeans in December trump ALL other crops or food sources! Those things play a huge part in any testing you may do and deer will walk thru cereals, clovers and brassicas all day long to get to those preferred food sources.
Heck...don't take my word for it, each of you have different habitat, deer, crops etc. so do some fair side by side testing of your own to help you make better choices for your whitetails and your budget....
