During the conversation, Guillermo addressed one of the major environmental challenges facing modern agriculture: <strong>the loss of reactive nitrogen and its impact on soil, water, and the atmosphere.<\/strong> <\/p>\n\n<p class=\"wp-block-paragraph\">The researcher explained the work being carried out as part of the <strong><a href=\"https:\/\/ceigram.upm.es\/en\/ceigram-presents-the-miren-4r-project-to-mitigate-the-impact-of-reactive-nitrogen-on-mediterranean-crops\/\">MIREN-4R project<\/a><\/strong> (Mitigation of Reactive Nitrogen through the 4R Approach in Mediterranean Crops), which focuses on <strong>applying the 4R approach<\/strong>(<strong>right source, right rate, right time, right place)<\/strong>\u2014to optimize nitrogen fertilization and reduce nitrogen losses, which pose agronomic, environmental, and economic problems. He also highlighted the differences between organic and synthetic fertilizers, emphasizing that nitrogen losses are not necessarily lower when using organic fertilizers. <\/p>\n\n<p class=\"wp-block-paragraph\">During the conversation, he also reflected on the importance of degree programs focused on agricultural sustainability\u2014such as the TAPAS master\u2019s program, which he completed as a student and where he now teaches\u2014and on the need to incorporate the economic dimension when addressing the sector\u2019s environmental challenges.<\/p>\n\n<p class=\"wp-block-paragraph\">To wrap things up, Guillermo invited another CEIGRAM researcher, Miguel Quemada, to participate in the podcast. We\u2019ll be on the lookout for its release so we can let you know. <\/p>\n\n<p class=\"wp-block-paragraph\">You can watch the full episode on the <a href=\"https:\/\/www.youtube.com\/watch?v=Y333U8J7knU\" target=\"_blank\" rel=\"noreferrer noopener\">UPM&#8217;s YouTube channel<\/a>, as well as on Spotify and iVoox.<\/p>\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Guillermo Guardia: Es importante conocer las patas econ\u00f3micas de la sostenibilidad\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/Y333U8J7knU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Guillermo Guardia V\u00e1zquez, a professor at the School of Agronomy, Food Science, and Biosystems (ETSIAAB) and a researcher at CEIGRAM in the Research Group on Agroecosystem Pollution from Agricultural Practices (COAPA), was the guest on the latest episode of SomosUPM, the podcast of the Polytechnic University of Madrid.
