I don't fertilize. How you like that for a "blind fert. recommendation shared on the internet"?!?
IMO after 15 years of planting food plots, and somewhat in direct "opposition" to your passion and focus when it comes to plots, is that food plots have been made to be more complicated than they need to be. (Insert exception/qualifier supporting statement here)...
Obviously, this whole conversation starts with "what's your goal(s)?", then it proceeds to "what resources do you have?", and somewhere in there it includes an analysis of "what do the deer really need?", and so on. But for the guy who says "something is better than nothing" and "throw and grow" is an adequate approach, you can still get a decent food plot. I'm fortunate to have good soil on the farm, so I really only fertilize every 2-3 years and only do so lightly. It's another chore and more $ that I don't see a direct ROI on, but again I have different goals and opinions than most food plot experts. It's an interesting conversation for sure.
This is a GREAT take. I often tell people that I care about soil, because I am passionate about it and the science behind it. I am passionate about how it impacts my family, from the food I grow for them and I enjoy the science- it pushes my brain to areas I never thought I could comprehend, and I like that challenge.
I am not, however, blindly accepting that I am having a major impact on my deer herd, even with planting 20 acres a year (10 acres 2x per year), in an area with limiting food (no ag around). If I want to make an impact on my deer herd, I shoot does and fire my chainsaw.....this is another topic for another day.
From a fertilization standpoint, there is a lot of science that would back up the hypothesis that "less is more" - specifically with pasture/food plot type crops. Liebig's "Law of the minimum" is an important consideration, but what about the "law of the maximum" - there are antagonistic relationships in the soil, which we must be cognizant of before we just blindly add product X, Y, Z.
For example - calcium drives MG in the soil, this is great if your soils are tight (MG tightens up the soil) and the base saturation of CA is below 60-70%. However, if you add lime (dolomitic) that has both, you may change the PH bot not have a positive impact on the soil structure, due to the antagonistic relationships between CA and MG. Similarly, over-fertilization of N, can drive CA out of the soil- not only as a pollutant but also a waste of money and further hurting the structure of the soil.
So from your perspective, of not fertilizing - why is that possible?
Well, without me looking at a soil test,I could make some assumptions based on my knowledge of you
@bowhunter1023 and the location of your farm.
1. You probably have a CEC of 14+ - this is good soil with the ability to bank a lot of nutrients, although at times you may argue it is more clay than you'd like, in certain spots.
2. Because of this CEC, we are able to have a lot of stored nutrients (cations -calcium, mg, k, NA)
3. We are often plotting in areas that have not been overly worked heavily (40+ years) and then oxidized from tillage, over-fertilization, etc.
4. You purposely and/or coincidently, have been planting legumes, grains, and brassicas. These inherently are attractive to whitetail but simultaneously are also great for the soil profile. These are fixing atmospheric N, mining nutrients, establishing fungi connections, enzymes are releasing those bound up minerals in the soil, that are being taken up by microbes, and released again as the plant dies or a deer eats/poops it out onto the field as a form of OM.
I share an absurd amount of information (only a portion of which I digest) to try to inform others so they can make informed decisions based on research and facts - vs. the marketing BS that is pumped into the DEER WORLD.
I have not used fertilizer on my plots in 3-4+ years - I strongly believe that we often don't need to for deer plots.
I have it on some newer plots, as I am working to balance base saturations of 60-70% CA, 10MG, 5%K - which then optimizes plant uptake and photosynthetic capabilities thereafter.
I share all of this to say, that many of us are blessed with our soil profiles in Ohio. However, if we were in Michigan or GA - it would be different and the attention to detail would be far more important be it plots, gardens, or farms.
PS - I am not anti fertilizer, tillage, pro-cover crop only, etc. I think all of these things are WELL worth considering with moderation.
All in all, we can use some or none of this information but if you are like me and care about money, soil health, nutrient density for the food you eat, and the deer consume, it might be of interest to you.
Always enjoy your take Jesse - I cannot emphasize the importance of goals and align these goals with one's passion. So so so important as a landowner. I believe if our only goal is Booners, we will be let down more times than not. If our goals are healthy soil - now that is something I can control!!
Thank you all!
