Implementing no-till and cover crops in Texas cotton systems
(American Phytopathological Society) Healthy soil leads to productive and sustainable agriculture. Farmers who work with, not against, the soil can improve the resiliency of their land. Because of this, practices such as no-till and cover crops and topics such as regenerative agriculture and soil biology have become increasingly important in the agricultural conversation.

The forests of the Amazon are an important carbon sink
(Helmholtz Centre for Environmental Research – UFZ) The world’s tropical forests store huge quantities of carbon in their biomass and thus constitute an important carbon sink. However, current estimates of the amount of carbon dioxide stored in tropical forests of the Amazon vary largely. Scientists at the UFZ have developed an approach that uses recent satellite data to provide much more precise estimates of the amount of biomass in tropical forests than in the past.
Amazon deforestation and number of fires show summer of 2019 not a ‘normal’ year
(Lancaster University) The perceived scale of the Amazon blazes received global attention this summer. However, international concerns raised at the time were countered by the Brazilian Government, which claimed the fire situation in August was ‘normal’ and ‘below the historical average’.An international team of scientists writing in the journal Global Change Biology say the number of active fires in August was actually three times higher than in 2018 and the highest number since 2010.
Volcanoes under pressure
(Technical University of Munich (TUM)) When will the next eruption take place? Examination of samples from Indonesia’s Mount Merapi show that the explosivity of stratovolcanoes rises when mineral-rich gases seal the pores and microcracks in the uppermost layers of stone. These findings result in new possibilities for the prediction of an eruption.
