I'll go over split applications of Nitrogen and give my opinion on the pros and cons of anhydrous ammonia, 46-0-0 and 28-0-0. The most important thing is that your only placing 40-60 % of the N down in the ground in the spring. A seedling requires less then this to make it to herbiicde time. When you apply a full amount of N your feeding the crop and the weeds and it is subject to loss. By doing a split you are reducing your risk by many times. This is the easy part the harder part is the next application of N. When i get some free time i will comment on this .

To apply the other 40-60% are you talking about dribble banding 28-0-0? Is there merit in foliar application of macro nutrients NPK?

Actually top dressing using proper nozzles and 28-0-0 is done alot. But the downfall is that you need a rain within the week to get it into the ground, Stream bars also help in reducing leaf burn.
Foliar applying nitrients is another way. It does work and its happening on thousands i mean thousands of acres. The nice thing about this is that you just add it in with your spray so one pass and it's done. As well herbicides are hard on plants group 2 can actually cost you a bushel or two to use them. Chem companies up the rate so that they know it's going to work. With a good nutrient you can even cut herbicieds

Looking foreward to your comments on the pros and cons on the n and split applications. I do not like putting anhydrous in fall anymore. Did not do it last year, spread 46-0-0 in front of my seedrill this sping but looking for a method that i would stick with. On some land not enough product came out so i top dressed some, but left out some land on each quarter to foliar apply for comparisons. A few people and I grew soybeans for the fist time in my area. So far i really like the crop. It is doing very well and no worries about disease, insects, or all the questions with fertillity. Getting less risk on my other crops sure would make farming more pleasureable.

How late should the second application be? A rain in a week, is that because of evaporation or gassing off? Would like to get a rain either way.

With a split application you always add some with he seed it's usually around the 40-60 % of total application. But heres the nice thing then you wait to see what the spring is going to be like. This year if this was done i belive the second application may not have been done because of the crop insurance claims. Instead if some n was required i would have done if foliar with about 3-4 pound and 75 cents a pound it would have been alot cheaper and less of a gamble. farming is a risk every year no matter how well you plan and the only guy that make out good and have little risk are the dealers. And if everything goes wrong they get there money and blame the weather. Does this sound good to anyone I think having more money in the bank at the end of the year is the goal no matter how it's done. For example this year if you could have not put down $ 20 worth of fertilizer and had that in the bank look it would be better. a 2500 acre farmn saving $20 equals $ 50 thousand dollars. It can be added later and but if your topdressing it does take that extra pass over the field. You can use a high clearance sprayer or even an old ground sprayer can work as long as it can push out the volume needed. 28-0-0 is 3 pounds per gallon so if your sprayer can push out 15 gallons an acre that would equal up 45 pounds of N you can apply. And for the right equipment it would be about a grand worth of stream bars so leaf burn is kept to a minimum. But foliar applying N can also work and it goes in with your spray. One pass does it. Timming is also a factor because at certain times of the growing stages N does better then others. Example for wheat it's before jointing around the 4-5- leaf stage. I've had many phone calls here at home by farmers and one so i know there is an interest but is it because of the year were having i hope not because just because next year may be great it's always a gamble. And farming smarter may not get you more yield but it may keep you from loosing yield as well which is also more money. If you crop can withstand heat stress better then canola will keep more flowers, cereals will still keepon with head development . I belive weather plays such a huge factor on the crops because they are so stressed because of the chemical and fertilizer we put on them. Somebody told be that they were walking through there field and a noticed canola leaves on the ground and yes i've seen this to. A very smart guy told this farmer that this was not normal and was caused by a sick and stressed plant and that healthy canols don't loose leaves. Why is it that leaf and stem rust and other diseases effect outr crops but the grasses around bushes sloughes and farm yards don't get theses diseases , some may do but never like our crops. is it beacuse thery are healthy and can fight off theses diseases. i wouldn't be suprised if the chem companies put out theses diseases just to sell more chemical and develope new owns as well.

And the rain in a week is beacuse of gassing off but agrotain can be added to. Also 28-0-0 is 50% plant available.
The thing about dry fertilizer to is that uncover it in the spring and you will find it spaced out unevenly with liquid it's a steady stream. Anhydrous almost killed me twice so i don't like it not be able to breathe scares the crap out of a guy.
You can still do a split with dry you just need a foliar application later which is very possible.
