Fertilizer question

[foragefarmer]

All the expert articles seem to say broadcasting in the late fall means it just ends up in the atmosphere.

Going to test that one myself this yr.

Best friend of mine worked for Koch for years, who along with my fertilizer dealer told me fall application is safe.

So all these years you listened to those experts Jazz? Hmmmmm that's funny.

That’s what I thought until seeing opposite last year
And 7’ of snow on top of it ?
Thought it would all end up in the cricks

If ground is dry, I think the moisture soaks into the ground and takes the fertilizer with it. You float fertilizer on wet soil and then get a big winter snowpack.. I think you would see the grass taller/greener in the ditch where the water comes out of your field.

Every year is a little different it seems.

I won't be cutting any corners next year. Regardless of price.

Same.

Direct seed, feed that seed… only…precision placement at time of seeding… 30% with seed (starter) 70% in deep band using high soluble fertilizer 2” below seedrow like crystal green P2O5… K2O in band also… 21-0-0-24 for S.

1000 ways to fertilize a crop! The lower the risk, increased efficiency…the better.

Blessings and salutations

The juice openers in the fall help us get going in may in the swamp other wise we would seed in June lotsa years
Every area is different

That’s the way we used to seed when we were using sweeps but moved to direct seeding all in one pass. There is a lot of years I wish we had the fertilizer on in the fall to help dry out and warm the soil in the spring, so far I have resisted.

We mostly just do ground going to canola
The cereals are usually zero till , double shoot dry 3/4” away from seed with an atom jet opener, no sweeps here just 3/4” knives, usually around 280-300 lbs product
Opening ground in fall Gains us a week in the spring which turns into two in the fall
And last few years juice is way cheaper in the fall
This stuff $.87

Also NH3 does not add extra salt to the soil , and whatever filler is put in the other 54% of the 46-0-0

We were told yrs ago NH3 makes the soil hard..
Most zero till guys here use dry..

[Sodbuster]

Couldn’t imagine going to dry, with our current setup using juice we can seed at least 160 acres a fill. If we were using dry we would have to handle and store a extra 600 tonnes plus replacing more hoses and we’d lose our 2’ of overlap provided with our pinpoint Nh3 system and be lucky to get 100 acres a fill using at least 200 more pounds a acre. With dry in canola I’d have to put down over 400 lbs which I doubt that the cart could handle without having problems.

Was told 45 years ago nh3 will gain 30 percent, I have seen it, since quit using it haven't grown the crops. Lost our dealer support.

NH3 vs Urea

Urea toxicity is well known… NH3 is little different, the release of the nitrogen is slower, because the N concentration is higher with NH3

Anhydrous ammonia applied to the soil initially has
an alkaline effect around the point of application~ However the ammonia nitrogen is gradually oxidised through the nitrification
ion process and therefore the final result iN an increase in acidity in the soil. The degree of acidity per unit of nitrogen applied is similar to urea or ammoniUJfi nitrate9 i.e.
about 36 ow·t. Ca Co. per m1it otC nitrogen. Sulphate of ammonia. is much more acid forming - 107 cwt. Caco3 per unit of nitrogen.
.Ammonia can attach itsalf to the clay particles in wet or dry soils~ In a wet soil the ammonia dis~olves in the soil mois'ture 9 as it is ·very soluble 9 and forms NR40H. The ammonium ions having a positive charge take theirlplace on exchange s:j.i:es of the clay particles perhaps displacing bases
such as ca++ Mg++ or K+. When the ammonia is $.applied in 9
dry so].1 it ca:n combine with a hydrogen ion on an! exchange site and thus result in exchangeable ammonium ions. ~oil organic matter also provides exchange sites to retain theIammonia. However9 some ammonia can also be fixed in an unavailable form by the orgar:dc matter.

Anhydrous ammonia is applied in a very narrow band. This means that the concentration of ammonia around the point of application is very highof Free ammonia is toxic to organisms so that this application of ammonia usually~sterilises a band around the point of applicationo This means that there are no nitrifying bacteria present in this zone to change the ammonium nitrogen into nitrite nigrogen and subsequently to nitrate. This limits leaching for a time. Gradually these bacteria carry on nitrification around the perimeter of this zone and gradually work their way into the centre to finally recolonise the whole zone.”
