Several, all used and abused.
I sent off two soil samples to Texas A&M's Soil, Water and Forage Testing Labratory. Welcome to Texas A&M University Soil, Water and Forage Testing Laboratory

The Ag Extension in Tyler gave me the waxed paper bags to put the dirt in and instructions on what to do. Basically, you take small amounts of dirt from all over the area you want tested, then mix it all together. Then you take that mixed up dirt and put it in the bag. I requested a routine soil analysis, which cost $10 each. There are more details samples that you can request that cost more money.

I have one area in my front pasture that I want to grow bermuda grass, but nothing grows there. The other area is where I want to put my food plot. I've removed allot of dirt from there, so what I have left is soil that's never grown anything. I want to plant peas and wheat there on a rotational basis.

Here is the result for my front pasture where nothing grows and I want to grow bermuda grass for livestock sometime in the future.

Here are my questions.

Do I just bring this report to the store and ask for so many pounds of each type specified? I'm guessing that it comes in sacks and I just spread it one at a time. Is that right? Then I disk it in and then I can spread the sead. Is that right?

The analysis has different amounts for the wheat and the peas, even though it's the same place, just diffent times of the year. Is it correct to assume that I add the difference from the first treatment to the next? Or do I spread the exact amounts specified in the anyalysis each time I plant a new crop? Or do I take another analyisis before planting each crop? It's just a food plot, so I'm not real concerned with being exact, but I would like for the plants to grow and do well.

I'm totally ignorant on what I'm doing here, so it's very likely that I'm not even asking all the questions that I need to ask. If theres's something that you think I should know, please feel free to offer any and all suggestions.

Thank you,
Eddie

Peas and Wheat have different requirements because they are different crops. Peas need less N as they fix their own nitrogen from the air. (actually a bacteria that grows with the roots does this but whatever) Peas are a legume and all legumes can fix their own nitrogen, in fact they will fix more than they can use so they actually improve the soil for the next crop.

Ideally you would test the soil before every crop and apply what you need. I don't know if you really need to do that by it may be helpful when first getting started.

what is the area of the fields? did you take the soil samples from the surface?

I'd take the analysis to the local fertilizer dealer and see what he recommends.:D :D

Eddie,

The first thing to do is get the lime applied. One ton per acre sounds low to me, but if that's what the test shows, then start out that way and do another test. It takes a good while for the lime to be assimilated into the soil. Ideally you would put the lime out in the fall ahead of the spring planting season.

Find a source for bulk lime....feed stores, coops etc. Don't buy it by the bag, way more expensive. Same for fertilizer...but it depends on the size of your plots...if small, then the spreader guys may not take the job and you will have to do it by the bag and do it yourself.

Regarding fertilizer. Buy a fertilizer for specific plots that most closely matches your analysis ratios. For example, for the bermuda plot, that is a 1-1-2 ratio approximately. You probably won't find that exact ratio, but a 13-13-13 is pretty close and very commonly available. To get 55 pounds of N per acre using 13-13-13, you would need to apply 425 pounds of fertilizer per acre.....13% of 425 is about 55 pounds of N.

Work the other areas the same way.


Those areas that have never grown anything probably need more than just chemicals...they probably need to have the organic matter in the soil built up and may need an application of gypsum if its tight clay. One thing I'd consider is to try to find a source of natural fertilizers, chicken farms, ranches, etc. and put out manure and disk it in. That would go a long way toward improving the soil, getting all those invaluable microbes going, and suport a small crop.

Eddie are these areas large enough and accessible enough to get a spreader truck from a local fertilizer company in? Buying lime by the bag to use in a cone spreader gets real pricey if you have much area to do. The last I bought was $3.80 per 40lbs. bag. Ag lime is much cheaper but does not spread with a cone spreader worth a darn. If you do try Ag lime with a cone spreader be sure to wear a respirator and eye protection the stuff can do bad things to you.

Used to be manure was one of the best, and i think there was(is) a whole science about it. Now they are talking about how much chemicals are secreted by farm animals in their manure it can affect the soil! So i am pickier about where it comes from if go to an outside source. Guess organic farms can charge now for chemical free manure?

Also have read about specific bacteria in the soil that eat antibiotics specifically have been discovered. What have we wrought??

charlz,

Thanks for your reply. I've been reading up on food plots and what grows well in my area, which lead me to cowpeas and winter wheat done in rotation. I'm also thiking about vitch, which is supposed to be good for improving the soils too. I have no experience with any of this, just what I'm reading and learning from threads on TBN.

Randy,

The first sample that is for bermuda grass is probaly close to half an acre. I went to the middle of six different bare spots in that field and dug a hole shovel deep. Then I took a slice of dirt that went from the surface to the bottom of the hole and put that in a pile. I did this at each hole so that I had dirt from all six areas and dirt from the surface down to the length of a shovel blade. I mixed it all together and then filled my sample bag with that mixture.

The food plot sample is an acre in size and done the same way. I'm not positive if I took six samples, or more. The process was the same, but my holes were dug based on covering the area.

Egon,

Taking the results of the samples to the farm supply store is the only plan that I've come up with. They have the seeds for what I think is a good price. I forget what that is right now, but when they told me the price a few months ago, I thought that it was pretty cheap.

I'm hoping to get some real world advice from some of you who have done this before and maybe help me understand what I'm getting into so that when I get the dirt work done, I'll be able to have a plan of action.

ML,

Thank you for taking the time for such a detailed reply.

I'm still moving dirt and have about a thousand yards to go before I'm ready to do anything to the soil. I could probably start disking next weekend for the actual food plot, but I want to get the rest of the field graded so that I can catch another couple dozen acres of water runnoff for my lake. No project has just one goal, and this one has an entire list of things that I want to achieve when it's done. LOL

I might be rushing things by trying to plant cowpeas this spring, but will try something no matter how late in the season it is. Then in the fall, I'll disk it in and plant wheat. As soon as I get it graded, I'll get the lime and disk it in. With just an acre and one ton listed, I'll probably just have a yard dumped into my pickup truck and spread it with a shovel as Steph drives though the field real slow. I've shoveld several tons of gravel and sand for making cement in a day, so a ton of lime shouldn't be that bad.

How long would you wait after applying lime in my situation before adding the other stuff and planting the peas? Do you think I'm rushing things by planting peas this season?

Thank you for the tip on buying fertilizer. I didn't consider them. For the small areas that I'm working on, that will probably be what I end up doing. I was sort of thinking that the farm store would have sacks of each thing that I needed and I'd buy them in the amount required. Now I wonder if that is even possible?

I've seen manure advertised before in the classified ads, but have never thought of buying any. For what I'm doing, I can see how that would be a really good idea. Does it make sense to have a few yards dumped onto my 16 foot trailer? I can cover it with a tarp and then just do the old shovel it out while being pulled around by Steph.

Mark,

I don't know what the minimums are for the fertilizer companies are for them to come out and spread the lime, but I'm guessing that I'm working on too small of an area for them to deal with. At just a ton per acre, and less then two acres total, I can do it fairly quickly on my own.

I plan to buy the lime by the yard. They will dump it into the bed of my tuck, which is the cheapest wat that I know of to get it. Then I was thinking of loading it into my seed spreader, which is a pull behind thing that I bought from northern tool. It will hold 100 pounds of seed. Then I got to thinking that if I'm shoveling it into the spreader, I can save a step and just shovel it out the back of my truck directly onto the field an save a few steps.

4720,

I hadn't considered that there is good manure and bad manure. Since this is just for fun and I'm not worried about maximising my plant growth, just getting them to grow, I'll probably end up buying manure from a local small scale ranch. I don't know one way or anohter, but feel safe assuming that what I end up with should be safe for growing food plots to feed the deer and hogs.

Thank you for all your replies,
Eddie

Eddie,

Depending on rainfall, soil conditions, how fine the ag. lime is, etc. it can take different times to be assimilated. The thing about lime and why I recommended you get it out first, in addition to assimilation time, is that the lime will help make your fertilizer far more efficient....plants will be able to make use of the fertilizer much,much better if the lime is present and assimilated. Otherwise, fertilizing first will end up wasting product.

The peas are a great choice for your area and soils...they fix N in the soils so planting them well before the winter wheat is a great approach. Make sure you innoculate the peas or add innoculant to the soil to make sure you get the N fixing going right.

It makes a lot of sense to me to dump a few yards of manure on YOUR TRAILER and YOU SHOVEL it. :) :). That stuff also needs some time to assimilate, but nothing like the ag. lime.

If it were me, and knowing you want to get something out this season, I'd just go ahead and get the lime out ASAP, then follow that with the manure, then begin planting and fertilizing...the problem is that it is getting late to catch this spring growing season. I don't know how late you can wait and reasonably expect the cow peas to make in your area, but I would guess, and its just a guess that if you don't get them out by mid-May, you probably should wait until fall. The lack of moisture and the heat will make it tough on the peas...but ask someone in your area, at the feed store where you buy the peas. They would know better than my limited knowledge.

i second the lime first suggestion and you can spread it best with a pull behind your riding mower spreader. the area you need to cover is not very much.
as for the other fertilizer you need i would just go buy some 10-10-10 at the big box store and read the directions on the bag leaning toward the heavy application side. if the soil is very hard then some disking after spreading will work to get it into the soil and keep it from just washing away. you can seed and fertilize at the same time.
