DKA,
yes, worked great. Is going to be replaced by a younger unit which he can get for a good price. So invest a little, get rid of the older unit & have a young unit on the farm.

this cultan seems a complete nightmare hassle.
no, for people who know how to use it and have a set up accordingly.
Fertiliser cost: less than straight spread
Yield: same or higher
much less yield fluctuations, especially when dry years
less fungi in most cases. Less growth regulators as well
Bonus: you can beef (spelling) the liquid up with some nice stuff which is further more eliminating using a sprayer. When this archived we have less environmental carry over by air drift etc.
you are right, it's a little complicated. but we have now many farms which use it >15 years, water sheds as well as they are able to comply with lower nitrate levels in drinking water, etc..

Been looking into Cultan and Ammonium nutrition for a couple of years now and I'm now convinced its the way I want to go, to the extent I have 400 tonnes of Ammonium Sulphate sitting in a shed and have bought a reconditioned DuPort 10m tool bar which as we speak I'm fitting to the Quadtrac with 3000l rear tank and 2000l front tank. I know it sounds crazy but the quad carries its self very indeed and I would rather have two sets of tracks running over growing crop than three sets of wheels with a tractor and tanker.
The idea is to supply the plant with 100% Ammonium N nutrition with no artificial Nitrate N thus setting the plant up in a root dominant "state" where Nh4 will convert to Nh2 in the root as apposed to converting nitrate to Nh2 in the stem/leaf resulting in a much more efficient conversion.
The plant roots will do an exchange of Hydrogen for Ammonium which will result in lowering the Ph in the root zone where there could be benefits with nutrient availability etc. I believe the "good" biology also prefer a lower Ph too.
Anyway.....you could say I'm quite excited about Cultan:)
I'm still learning and have lots and lots still to learn but I do think that Cultan is key to achieving our long term goals on our farm.

I think the prediction of lower ph, came true. According to my agronomist.

Sulphate of ammonia will lower ph in root zone when placed with seed at drilling. Helping to make P more available to the roots. roots do not mind growing in AS unlike other forms of N
@York explained to me so maybe he might expand

when we use N at drilling its usually straight AS for this reason

How come in a nutrient availability chart P seems to be most available at between 6-7.5 then Philip?
Yeah I was thinking that after and that's why I tagged at York to explain. Basically roots do not mind growing in AS, surely a dip in pH is routine anyway and application of lime is required. @Knockie doesn't seem to be here anymore. :eek:
 
Although cant be as bad as the insanity of digestate spreading with 80 tonne machines!

I must admit there’s weight in this point. Whilst the digestate was free you can put up with the mess which is surprisingly not to bad. A 30,000 litre tanker over 5 axles (Claas xerion setup) does a tidy job. However these Holmer things over 2 axles but only carrying 20,000 litres do make a mess. Add in they are now charging for the digestate pretty much stops it in its tracks I think. It needs to be free to put up with the mess in my view as tractor tankers making runs around the outside of fields needs sorting out and then there’s flattened crops.

27m unit running >2nd season. doing a good job.
prefer running 2x 36 m as much easier to navigate with power line post's & odd shaped fields.
good to see that eastern neighbours are not motivated by the nay saysers but do it.
As you don't need to comply in future to EU laws, so no need to watch N efficiency. with US trade deal you are going to compete with N-hydrous ammonia applied, which is the cheap Cultan.
Now with >100 n/ha in the soil - soil samples from last month indicating, not much room left for N application when you need to get rid of serious ammounts of digestate of animal waste on top. We need to get N efficiency up.
