Pesticide “ghosts” can haunt organic farms for decades
Most commercial crops grown around the world are treated with pesticides. But some farms are now switching to organic practices to avoid the risks that pesticides pose to human and environmental health. However, new research shows that past pesticide use can still “haunt” fields that have long been converted into organic farms. Published recently in Environmental […]

CO2 to the rescue: Elevated carbon dioxide concentrations can reduce the negative effects of drought on crops, study finds
American and Brazilian researchers evaluated the possibility of elevated carbon dioxide (CO2) concentrations reducing the negative effect of drought on physiological parameters and the growth of Manihot esculenta (cassava). They reported their findings in an article published in the journal Archives of Agronomy and Soil Science. The researchers grew cassava with 390 ppm or 750 ppm of CO2 […]

Bacterial populations use seepage water to travel between the surface and subsoils
In this study, German researchers investigated the mobilization of certain bacterial populations present in the soil after dynamic hydraulic events. Their findings were published in the journal Soil Biology and Biochemistry. During extreme precipitation events, substantial amounts of organic matter are mobilized, resulting in fluxes in carbon from the topsoil to deeper mineral soil and groundwater. […]
