Animal manures are suspected to be a major source of nitrate leaching due their low nitrogen use efficiency (NUE) by crops. However, actual measurements from animal manure under field conditions scarce. In an on-farm trial in Switzerland over 2.5 years, we used 15 N labelling trace the fate cattle slurry soil-plant system and test whether more was leached than mineral fertiliser. The experiment...

Penetration of cabbage roots by Heterodera schachtii was suppressed 50-77% in loamy sand naturally infested with the nematophagous fungus Hirsutella rhossiliensis. When Heterodera schachtii was incubated in the suppressive soil without plants for 2 days, 40-63% of the juveniles had Hirsutella rhossiliensis spores adhering to their cuticles. Of those with spores, 82-92% were infected. Infected n...

Hydraulic fracturing drilling technology can cause a high risk of surface spill accidents and thus water contamination. Climate change together with the demand rapid increase in industrial agricultural activities are valued reasons why we should all care about availability resources protect them from Hence, purpose this study is to estimate associated site contaminated benzene oil spillage its ...
