With spring fast approaching, farmers in many parts of the country will be planning a date to apply their first round of chemical fertiliser.
Farmers in 11 counties will be permitted to spread chemical fertiliser on their land this weekend.
Farmers in zone A, which comprises 11 counties, will be permitted to spread chemical fertiliser from Saturday, January 27.
Farmers in Zone B will be permitted to spread chemical fertiliser from Tuesday, January 30.
For farmers in Zone C, they will be permitted to spread chemical fertiliser from Thursday, February 15.
Chemical fertiliser spreading
Offering advice for spreading chemical fertiliser, Teagasc urged farmers to not apply fertiliser N on fields that receive slurry in the first round.
They added farmers should never apply fertiliser on waterlogged or frozen soils and to only apply fertiliser N when soil temperature is greater than 5°C and rising.
Teagasc advises farmers to not apply slurry or fertiliser if a yellow, orange or red rainfall warning is in place or is forecast within the next 48 hours.
