CSIRO and Bayer to focus on sustainable crops
This collaboration will develop and apply models to assess the system-wide consequences of new-generation cereal crops in the face of global environmental and food security challenges. The project will assess the full environmental impact of the crops, including their influence on the carbon footprint of cereal production. This program will build on a long-term cereal research agreement between the two organisations. The Director of CSIRO´s Sustainable Agriculture Flagship, Dr Brian Keating, said new generation crops offer enormous potential to help Australia and the rest of the ... |

Even soil feels the heat
Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in this week`s issue of Nature. The scientists also calculated the total amount of carbon dioxide flowing from soils, which is about 10-15 percent higher than previous measurements. That number — about 98 petagrams of carbon a year (or 98 billion metric tons) — will help scientists build a better overall model of how carbon ... |
