Arpa (Hordeum vulgare L.) Yetiştiriciliğinde Moleküler Ölçekte Karbon Salınımının İzlenmesi ve Sürdürülebilirlik Açısından Önemi

Öz

Günümüzde Arpa (Hordeum vulgare L.) yetiştiriciliğinde karbon salımının moleküler düzeyde izlenmesine yönelik güncel yaklaşımlar ve bunların tarımsal sürdürülebilirliğe katkısı üzerine yürütülen çalışmaların yok denecek kadar az olduğu belirlenmiştir. Küresel sera gazı emisyonlarının azaltılmasına yönelik artan ihtiyaç, karbon akışlarının yalnızca fiziksel değil, moleküler mekanizmalarla da izlenmesini zorunlu kılmıştır. Bu doğrultuda, izotop etiketleme (¹³C, ¹⁵N), metagenomik ve metatranskriptomik analizler ile FTIR ve NIR spektroskopisi gibi ileri teknolojiler, arpa rizosferindeki karbon dinamiklerinin ayrıntılı bir şekilde çözülmesini mümkün kılmaktadır. Karbon salımının kaynağı, zamanlaması ve mikrobiyal topluluklarla olan etkileşimleri bu yöntemlerle belirlenebilmekte; böylece düşük emisyonlu yönetim stratejileri için bilimsel temelli karar destek verileri elde edilebilmektedir. Ayrıca, karbon kullanım verimliliği yüksek mikrobiyal grupların ve stres koşullarında daha az karbon salımı gerçekleştiren arpa genotiplerinin teşhisi, mikrobiyom temelli ve genetik ıslah odaklı uygulamalara olanak sağlamaktadır. Araştırmamızda, karbon ayak izinin azaltılmasına yönelik olarak mikrobiyom yönetimi, hassas gübreleme, minimum toprak işleme ve dijital tarım teknolojilerinin entegrasyonu gibi öneriler tartışılmış; yaşam döngüsü değerlendirmesi (LCA) ve sensör tabanlı izleme sistemlerinin önemi vurgulanmıştır. Arpa tarımında karbon salımının moleküler düzeyde izlenmesi, hem iklim değişikliğiyle mücadelede hem de tarımda çevresel sürdürülebilirliğin sağlanmasında kritik bir araç olarak değerlendirilmiştir.

Monitoring Carbon Emissions at the Molecular Level in Barley (Hordeum vulgare L.) Cultivation and Its Significance for Sustainability

Öz

It has been determined that studies focusing on the molecular-level monitoring of carbon emissions in barley (Hordeum vulgare L.) cultivation are extremely limited. The growing need to reduce global greenhouse gas emissions has made it imperative to trace carbon fluxes not only through physical means but also via molecular mechanisms. In this context, advanced technologies such as isotope labeling (¹³C, ¹⁵N), metagenomic and metatranscriptomic analyses, as well as FTIR and NIR spectroscopy, enable a detailed resolution of carbon dynamics in the barley rhizosphere. These methods allow for the identification of the sources, timing, and interactions of carbon emissions with microbial communities, thereby providing scientifically grounded decision-support data for low-emission management strategies. Moreover, the identification of microbial groups with high carbon use efficiency and barley genotypes that emit less carbon under stress conditions facilitates microbiome-based and genetic improvement-oriented applications. In our study, integrated approaches such as microbiome management, precision fertilization, minimum tillage, and the incorporation of digital agriculture technologies have been discussed as potential strategies for reducing the carbon footprint. Additionally, the importance of life cycle assessment (LCA) and sensor-based monitoring systems has been emphasized. Monitoring carbon emissions at the molecular level in barley agriculture is considered a critical tool both in combating climate change and in ensuring environmental sustainability in agricultural practices.
