Check your report again. I'll bet that's not "lbs/acre," but it's "units" per acre. In other words, ammonium sulphate contains 21 units of N per 100 lbs. To get 95 units of N, you will need nearly 500 lbs per acre. Same with the Phosphorus. I think that the ammonium sulphate will take care of your Sulphur requirement.

I double checked and it says "95 lbs N/acre". I will be calling them today and will confirm with them.

That is a common reference in Texas. Per acre, so that would be 95 units of nitrogen per acre, if your using say 32-0-0 (32nx3=96) you will need 300# per acre to reach that goal.

I put out the recommended amount after each cutting, (per the Ag office)
Usually You wont need a blend like 32-10-10 after the 1st application (tad cheaper), you may be able to use a straight N since the Sulfur and P (Potash) last longer, but you will probably want to use the blend on the last application, so 1st and last.

If you are planning on running your own cattle on it, Prickly Pear is not nessasarily a bad thing to have. During this drought it has saved us alot of money burning it for the cattle to eat. I have cleared alot with the Ratchet Rake in an area I am trying to prep for the same as you this past year though.
Where in texas are you? I have a ripper for pasture/coastal I would lone for you to try if we are not to far apart. its home made but works good.
We are 50 miles south of SA.

Up here in the north, it is common to split up the N application, after each harvest - if you get 3 cuttings, I'd apply all the other fertilizers in spring, plus 1/3 of the N.

Then after 1st cutting, apply another 1/3 of the N. And again after the 2nd cutting.

I don't think grass hay would need 300 lbs of N applied in the year, I think the 95-100 is for the whole year.... Too much N and the hay becomes a problem for some livestock.

P, k, Sulfar, and the rest stays in the soil pretty well, so apply all that in the first application. N tends to be used by a greedy crop inefficiently; or it tends to wash away in heavy rains. So it is better to split up the N applications.

There was no recomendations for K fertilizer? Your soils are plenty high perhaps?

As others are mentioning, there is 'actual' N and there is 'lbs of N.' It seems confusing at first - you should apply 95 actual lbs of N in a year. So if you are using a fertilizer that is 32% N (it would be called a 32-0-0) then you need to apply about 300 lbs of that stuff per acre, to get an actual 95 lb application of N.

Some of my thoughts might not apply to Texas, remember things are done differently in different regions. Good of you to seek local extension advice for the real word.

Case485Guy - I do not plan to run any cattle on it at this time. I live in Houston (day job and kids) and the ranch is in Stephenville (about 4.5 hour drive north). So for now, hay production is my only option and need. I appreciate the offer of using your ripper. Not sure locations work out right now but will keep in mind for the future. :thumbsup:

Rambler and Western - thanks for explanation on "actual" versus "lbs of". It is inline with my thinking and findings so far as well so was good confirmation.


Local ag extension agent to call me back later this week to discuss details of samples and how best to proceed. Also have call into respected local fertilizer waiting to hear back on his opinions and costs. :eek:
