Nitrogen Fertilizers, How often to apply?

I'm not sure of this is the right forum but here goes.

I work on my own farm and I'm not sure how often and how to apply nitrogen fertilizers to save time and my back.

I apply granular urea as a side dress to my crops(loose leaf lettuce) then irrigate after to prevent too much nitrogen loss. I do this split application method every week then stop near plant maturity.

My question: Is it more efficient to apply more granular urea to lessen the application time? For example, instead of applying urea every week(about 5grams per plant), I should apply 10 grams then Re-apply after two weeks(instead of every week, application will be split to every two weeks).

Second question : Is this a viable and efficient way of applying granular urea?

Thanks for the responses 😊😊
First question, is where are you based?

Second, is there a reason for continual N application to the crop as opposed to just applying it to the crop after the plants are established?

I have no experience of lettuce growing other than in the garden for personal use... :)

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...
