To cold for liquid fert?

[Beefsmith]

Our winter crops really need their N2 but the forecast is minus temps for the next 7 days and fairly windy. Today’s weather is suggesting 5 degrees and no wind so it’s good conditions. Shall we do it or will tomorrow’s frosts bite us in the backside?

It’s more conditions at the time and just before that affects liquid N.
I put some on some rape a few years ago just before a frost which ended up much colder than was forecast. There was no frost where each stream of liquid N had gone and no real scorching.

I would crack on, crops will have hardened off by now. We are full on today.

I was given the advice that it's OK to put in on before a frost.
But after a frost, under no circumstances put it on before the crop has fully thawed.

I am advising customers to wait until this cold spell has passed........trouble is spraying is also stacking up so I get the pressure however IMO best advice is wait a while until it warms up a little and the frosts have gone

I'd get on with it - when it warms up there will be lots of soft lush growth.

There is a big but... wind worn leaves are dewaxed and recent sprays will also soften the crop up e.g. SU graminicides. I've never noticed damage around frosts but would not dream of applying it to a damp leaf that is going to dry out - that includes one with frost on it.

 

[Beefsmith]

Well we did it so will see what happens.

More important to avoid hot windy conditions than cold, relatively calm ones IMO. As Brisel says, dewaxed leaves can be unhelpful.

been on it all week here - just start late and finish early

Drizzle all day here. Perfect for liquid fert. Getting all Winter Barley done and carry on with WW.
