t leaching because plants can start accessing the nutrients soon after application, lower distribution costs for producers and reduced risk of spills compared to manure haulers/tankers, reduced traffic and potential damage to roadways, and reduced soil compaction.
However, issues have been expressed regarding odor spikes, risk of influencing air quality with particulates, surface and groundwater effects, and reduction of aquifers. Therefore, these issues should be evaluated for the local area before irrigation equipment is purchased for the sole benefit of manure distribution.
