To reduce PM]0 emission from plant production, different tillage, arable connected and not arable connected technologies are available. Such are timed tillage, integrated pest management, agricultural equipment conversions and soil moistening with water spraying. The use of artificial windbreaks and mulching also helps withholding the erosion caused by the wind, thus reducing PM emissions. Also a wide variety of methods are available during the harvest, which reduces the amount of soil particles and chopped plant material residues getting into the air. The major source of secondary PM, the ammonia reducible with well-timed manure spreading and quick application on the field, in compliance with the specifications of the 'Nitrate Directive'. The amount of dust resulting from livestock breeding can be reduced by changing the feeding technology, moistening the feed or using water or oil spraying. The PM_(10) emission of the manure can be reduced by using additives, covering up the storage or using a biofilter as well. The agricultural machines are also significant emitters of the PM_(10). Diesel engines produce primary particles (soot), which would be filtered out by using DPF (Diesel Particulate Filter). Shift to gas drive would be a realistic and environmentally friendly solution compared to diesel. Due to lower oil consumption, higher oil drain interval, slower engine wear substantial cost savings could be achieved. By burning of gas, much less hydrocarbon, carbon monoxide and nitrogen oxide would be emitted into the air, unlike use of petrol. 收起
