Agriculture contribute 70-90% of N and 60-80% of P non-point pollution load to the Baltic Sea

Water pollution source – agricultural run-off

• Non point sources (surface and drainage run-off) • Point sources (leakage from storages, feedlots, manure dumping sites)

Non-point agricultural pollution monitoring

Bērze (1994) Drainage field 76 ha Sm.catchment 360 ha

Vienziemīte (1994) Sm.catchment 592 ha

Drainage field 67 ha

Mellupite (1995) 15 Drainage plots (0.12 ha)

Drainage field 12 ha Sm.catchment 960 ha

Auce (2014) Sm.catchment 68 ha

Monitoring methods Impact of other pollution sources should be excluded, thus providing information on agricultural non point source pollution in several geographical scales:

Monitoring results (non point source)

Nitrate Directive (1991) Phosphorus ?

P tot = 0,05 - 0,1 mg L-1 ?

Monitoring results (non point source)

7

Water Framework Directive (2000)

Good ecological status for water by 2015. Ecological status is determined also by

chemical quality elements.

Establishment of reference conditions and class boundaries of the nitrogen and

phosphorus?

Does same chemical water quality criteria should be used for river water bodies and also

for run-off from fields of the agricultural land (drainage collectors) / small catchments

(drainage channels, small rivers)?

Point source agricultural pollution monitoring

Bauska pig farm (1995) Sm.catchment 800 ha

Ogre pig farm(1995) Catchment 300 ha

Auce pig farm (1995) Sm.catchment 60 ha

The Bauska farm (12 000 fattening pigs per year, 55 000 m3 pig slurry per year) was established in 1976. Until 1987 tractor moved tankers were used for slurry application. In 1987 a slurry irrigation system was installed (226 ha). Today the pig production is 8000 -10 000 fattening pigs, but the slurry utilisation area is only 50 ha. Small catchment - 800 ha(slurry lagoons, dumping site) has been used for monitoring. Another catchment -750 ha of intensive agricultural land has been used as reference site.

Ogre farm

The farm was built for 30 000 slaughtering pigs in 1974. Slurry application in area of 462

ha (slurry 137000 m3/year). The farm was closed in 1992.

Monitoring area - small catchment 300 ha. Several old lagoons still are full with slurry

sediments. Heavy polluted slurry dumping sites due to leakage accidents.

Vecauce pig farm was established in 1987 for the production of 6000 fattening pigs per year. After separation, the liquid manure was stored in a lagoon and used for irrigation an area of 32 hectares. Today tractor tankers has been used for spreading of slurry.
