| I'm currently arguing back and forth with a highway "inspector" that is telling me we have to use 34-0-0 on a particular job. I tell him I can't find any 34-0-0 in the area right now but I can get plenty of 21-0-0 or 46-0-0 and would just have to adjust the quantity accordingly to make sure the same amount of "N" goes out to the acre. As long as the same amount of N is spread out over the acre what does it matter? Job called for 50# of 34-0-0 to the acre just for the record. |

Try to purchase the 46-0-0 and adjusts your application rate to reflect the change in the amount of nitrogen that comes with the new bags of fertilizer. What is the application rate that you were going to use for the 34-0-0? Whatever it is, you can probably cut it by roughly 25% and still have the same effect that you would have had if you had used the 34-0-0 instead. |

I guess it's the formulation. And why they want a particular kind for availabilty, environmental fate (leaching, plant availability, volitilization etc), or a myriad of reasons. But ultimately it won't matter that much.
21 is ammonium sulfate 46 is urea 32 is ammonium nitrate |

Trying to get out of special ordering more but as soon as I heard this was a Fed job, I should have just ordered it already.

Just Mix your 46-0-0 & 21-0-0 at a 1:1 ratio, & it will be 34-0-0, ... well, 33.5-0-0 = close enough for "government work" Or you could see how much N is in that 50# bag of 34-0-0 which I think is 17# and divide that by 46% (46-0-0) and just use 37# but arguing with the DOT about it when he's clutching that little red book is almost a complete waste of time. |

Job called for 50# of 34-0-0 to the acre just for the record. 50# of 34-0-0 yields 17 lbs/acre actual nitro. 50# of 46-0-0 yields 23 lbs./ acre actual nitro. So. 23/17=1.35, means 50# of 46-0-0 will cover 1.35 acres Then 50#/ 1.35 = 37#/acre of 46-0-0 is the same as 50#/ acre of 34-0-0 37 X 46%= 17.02 lbs. and 50 X 34%= 17 lbs.

Posted Via AR15.Com Mobile Nitrogen Phosphorus Potash 46 0 0 They are wanting only nitrogen fertilizer applied. The numbers caption the % of actual product. In this case they want 50# per acre of 34% nitrogen and he has 46 % thus it will take less pounds per acre.

All of those are nitrogen only (no P,K). So they obviously have the nitrate requirement for a different reason than what you postulate. |

He was dealing with a highway inspector so he is prolly seeding the right-of-way adjacent to some type of highway construction. I worked as a highway inspector and most D.O.T.'s call out dry fertilizers for their seeding contracts. I understood his question and I believe he understood my answer.

You could use all of those formulations in granular or in solution as a spray. While the customer may specify either physical state, that doesn't change the fact they requested a specific form of nitrogen fert (ammonium nitrate). |

What part of MS are you in? I ask because there's a massive project going on ~5 minutes from here (hwy 9).
And yes, in theory different N formulations vary in the rate at which they're released, but if you're broacasting it on the surface, it makes virtually no difference in how the plants grow. You really should have looked for a way to get forgiveness instead of permission here.

I would imagine a strong root system would be very important for this application. You definitely don't want a quick green up and rapid growth above ground with a poorly established root system.
Do some reading, they're really not the same. Posted Via AR15.Com Mobile |

If one is in the industry one may have to follow the S.W.P.P.P. designed for the project. Failure to do so can become quite expensive. To save a Google that would be the Storm Water Pollution Prevention Plan. It's one of those programs "big brother" watches. One is required on projects that disturb more than 1 acre.

Dial it back further and go over it twice if he is worried about distribution or some other insane minutia. |
