If we get a call-out about 2,4-D mixing
issues, it often has ammonium sulphate in the mixture, so today we will show you how
to use ammonium sulphate correctly. You’ll be using ammonium sulphate to overcome
water issues such as hardness and bicarbonates. Put the ammonium sulphate into the tank first
to help ameliorate the water – the important part is to make sure it’s dissolved. To speed
up this process this is where you could use liquefied ammonium sulphate such as Liase.
So this ammonium sulphate has dissolved now. Into this other tank we’ll demonstrate undissolved
ammonium sulphate – we’ll put the 2,4-D into the undissolved ammonium sulphate and give
it a bit of a stir (agitate as if in the tank). You can see quite quickly it goes an off-yellow
colour and it can get sort of gluey and gluggy in the tank and block your filters and nozzles
up quite quickly. So that’s the reaction between the 2,4-D and the UNDISSOLVED ammonium sulphate within that tank. We’ll replicate that mix again, but this time
we’ve dissolved the ammonium sulphate in our tank. We’ll put in our 2,4-D, give it some
agitation… This is the end result of ammonium sulphate
that was undissolved before the 2,4-D went into the tank versus ammonium sulphate where
it was dissolved in solution and then the 2,4-D has gone into the tank. I hope this demonstration shows you a very common mixing error.
