So my silage fields were given 90 units of nitrogen can based on the 12th of may. 40 days ago. The way the grass has grown and the forecast I am thinking about doing one field for haylage next week. Although worried about nitrogen in the grass? Any thoughts? Thanks

It could of been using more than 2 units a day with the good weather. Did it get washed in quick?

It got a good wash in a couple days later. I will probably need to have the grass tested to see if nitrogen is left in it. Would worry if I made it with nitrogen it could go black in the bales....

General rule of thumb is 2 units/day.So 45 days from an 90 unit application .Next week should be fine.

Depends on your weather. Put fert on some grazing that was getting away from us 14th may and it's not done anything. Guess the rain earlier this week will have washed it in.

2 units per day at optimum. If in any doubt precut test it.

Is testing accurate ? How many samples would you need to take to be sure?

You make a composite sample and send of one sample per field. I used to get a pair of shears or just pull handfuls of grass up at 6-10 locations in each field, mix them and send it off, results back by email within 48 hours. It's only as accurate as your sample, but it's more reliable than counting units per day.
