N Rules for a pulse/ cereal mixed crop?

Does anyone know what the rules are concerning N fertiliser for a field of a mixed crop of peas and oats. Obviously not allowed on a pea crop but didn’t know if this was the case on a mixed crop? I was thinking of a low rate, perhaps 30-40 kg/ha N to help the oats along and hopefully not be detrimental to the peas fixing N.

Is there in fact No N Max for peas? Like beans?

Well, here's a screenshot from RB209 saying no N, but with enough ambiguity to apply a bit to help establishment.

As an aside, NZ pea growers apply a bit of DAP to help early development but they have no NMax to worry about, just research to say what works best.

Only crop with no NMax is oats. Peas and beans have an NMax but it’s zero
Little confused

:LOL: I was taught on FACTS that If they ask what the NMax for peas and beans was, the answer is zero and if they asked for the NMax on Oats then the correct answer is there isn’t one

Do you farm in an NVZ?

Up until the last revision of the PGRO pulse agronomy guide, they used to recommend using ammonium sulphate on peas to supply sufficient sulphur, with the amount of N applied doing no harm whatsoever
 

Rejuvenating swards: Which option is best?

Written by Brian McDonnell

Maintaining grass quality during mid-season grazing is important. Farmers can maintain quality by entering ideal grazing covers of 1,300 – 1,500kg DM/ha, and grazing down to a residual of 4cm every rotation.

If you are now in a situation where cows are not cleaning out paddocks as well as they should be, leading to the development of steamy grass within the sward, here are some options.

Common options for rejuvenating swards include:

  1. Take a silage cut, probably into bales, remove the material and start again with the aftermath...
