River diversions may cause microplastics to remain longer on land and in streams before reaching oceans

A new study reveals that diverting streams and rivers for irrigation can significantly extend the time microplastics spend in river catchments. Researchers found a strong link between urbanisation and microplastic concentrations, with microplastic loads increasing downstream of more urbanised areas.

How much nitrogen does corn get from fertilizer? Less than farmers think

Research shows that corn takes up about 67% of its nitrogen naturally from soil, rather than fertilizer. However, applying different forms and timing of fertilizers can improve efficiency, with nitrate being the most efficient source. Banding placement was also found to be more efficient than broadcasting.

Cover crop management: trade-off between carbon benefits, crop yield

Researchers used an advanced ecosystem model to assess the impacts of winter cover cropping on soil organic carbon accumulation. They found that growing cover crops can increase SOC by 0.33 megagrams per hectare per year and that SOC benefits can be improved through increasing cover crop biomass.

Drones over Texas reveal agricultural damage caused by wild pigs

Researchers used drones to capture images of corn fields damaged by wild pigs in Texas, finding an average loss of 3,416 kg of corn per hectare and a direct cost to producers of up to $48.24 per hectare. The damage occurred mainly in later growth stages, when corn ears were maturing.
