Farmers will be allowed to spread slurry on their land in just one week once the prohibited application period reopens.
On January 12, 2017, farmers in the parts of the south and east of the country will be allowed to spread slurry on their land.
Farmers in these areas will also be allowed to spread slurry, farmyard manure and chemical fertiliser after this date.
The second batch of counties will be allowed to spread fertilisers after January 15, with counties based along the western coast making up the bulk of this group.
The final four counties, Monaghan, Cavan, Leitrim and Donegal, will have to wait until January 31 before they are allowed to spread fertilisers on their land.
The closed periods began at different times depending on the fertiliser type, with chemical fertiliser being prohibited from being spread since mid-September.
Last year, the slurry spreading deadline came into affect on October 15, 2016, despite numerous calls by farmers and politicians alike to extend the deadline due to poor soil and weather conditions.
However, farmers who found themselves in an emergency could contact the Department of Agriculture, Food and the Marine who would look at cases individually, according to Minister Michael Creed.
Farmyard manure was the last type of fertiliser allowed to be spread before its closed period came into affect at the beginning of November.
The aim of the closed period is to protect ground and surface water, including drinking water.
The regulations also prohibit the spreading of slurry at any time of the year when the ground is frozen, waterlogged or heavy rain is forecast in order to prevent slurry running off into waterways.
