The Irish Farmers' Association has called on local authorities to introduce stronger deterrents against people who dump litter in the countryside.
The association recently highlighted the threat of fines of €130,000 on landowners for rubbish left by others.
In light of the increasing problem, the IFA says it is time to review the penalties imposed on the perpetrators of illegal dumping.
IFA Deputy President Eddie Downey also urged farmers to report any incidents of illegal dumping in the countryside to their local authority, which is responsible for keeping the countryside litter free.
He made his remarks following an incident in which a farmer who challenged illegal dumpers was said to be seriously assaulted.
Mr Downey said he could understand the frustrations of farmers who find people spreading household rubbish on their land, but cautioned against engaging with them.
In this incident, he said the farmer had endured persistent and indiscriminate dumping on his land.
