China will launch campaigns to curb pollution from livestock and poultry farms, as well as the excessive use of fertilizers in horticulture, to fight pollution in rural areas, a top agricultural official said on Tuesday.

The Agriculture Ministry will kick off a campaign this year to treat pollution from animal excrement on livestock and poultry farms to improve the rural environment, Han Changfu, minister of agriculture, told a news conference on Tuesday on the sidelines of the two sessions.

"We have made it a clear target that all the excrement from large-scale farms will either go through harm-free treatment or be reused as resources," he said.
