Pick Up1391. Carbon is a Wonderful Partner for Nitrogen in Protecting the Earth
Now that we can use more fertilizer, we no longer have to worry about food. But it's not all good. If too much fertilizer is added to fields, the reactive nitrogen that plants don't use can pollute rivers and the air, causing various environmental problems. This is becoming more common, so we need to take action quickly. We will introduce a study that investigates whether adding charcoal to soil can keep the nitrogen in fertilizer in the soil for longer, allowing nitrogen to be used without waste.

Pick Up1088. Ancient Wild Relatives Hold Key to Climate-Proofing Global Wheat Supply
https://www.cimmyt.org/news/ancient-wild-relatives-hold-key-to-climate-proofing-global-wheat-supply/Crop wild relatives that have survived changing climates for millions of years may provide the solution to adapting wheat, humanity's most widely grown crop, to climate change. Two new studies led by the International Maize and Wheat Improvement Center (CIMMYT) reveal how tapping into this ancient genetic diversity can revolutionize wheat breeding and safeguard global food security. -
Pick Up1001. Scents from Tropical Forests
Plant scents are all around us. Many of the scents used in aromatherapy, especially for healing the tired mind and body, are derived from tropical forest plants. You may not know the names agarwood, sandalwood, and borneol, but you may have encountered their scents. In fact, only a few people have never smelled their scents. Tropical forests are an important source of timber resources, but these non-timber forest products also support people's livelihoods and help generate income for sustainable forestry. Here are some scents that come from tropical forests. -
Pick Up916. Call for Participation in the Platform for the Utilization of Joint Crediting Mechanism in the Agricultural Sector
We are pleased to invite participants to the Platform for the Utilization of Joint Crediting Mechanism (JCM) in the Agricultural Sector. This platform has been established by JIRCAS to promote JCM in the agricultural sector in developing countries through information sharing, standardization (development of MRV methodologies), and cooperation and advice to government agencies. We will cooperate in efforts to apply JCM in the agricultural sector through broad exchange and sharing of information among concerned private companies, research institutes and government agencies.
