Azot, bitkisel üretimin temelini oluşturan ve fotosentez, protein ve nükleik asit sentezi gibi hayati süreçler için gerekli bir makro besin elementidir. Ancak, mevcut gübreleme uygulamaları genellikle azot kullanım verimliliği açısından düşük sonuçlar vermekte ve bu durum hem ekonomik kayıplara hem de ciddi çevresel sorunlara yol açmaktadır. Derin azotlu gübreleme, azotun bitki kök bölgesine daha yakın derinliklere yerleştirilmesi işlemidir ve bu yöntem, azotun bitki tarafından daha etkin kullanımını sağlarken, yüzeyden buharlaşma ve yıkanma yoluyla kayıpları önemli ölçüde azaltabilir. Bu makale, derin azotlu gübrelemenin tanımını, önemini ve tarımsal üretim üzerindeki etkilerini ele almakta, geleneksel yüzey gübrelemesi ile karşılaştırmasını yapmaktadır. Ayrıca, uygulama teknikleri ve optimizasyonu, avantajları, zorlukları ve riskleri ile uygulama alanları ve durum çalışmaları incelenmiştir. Sonuç olarak, derin azotlu gübrelemenin bitki büyümesi, verim, azot kullanım verimliliği ve sera gazı emisyonları üzerindeki olumlu etkileri göz önüne alındığında, tarımsal üretimde yaygın olarak benimsenmesi gerekmektedir.

Deep Nitrogen Fertilization in Agriculture

Öz

Nitrogen is a fundamental macronutrient essential for vital processes such as photosynthesis, protein synthesis, and nucleic acid synthesis in plant production. However, current fertilization practices often result in low nitrogen use efficiency, leading to both economic losses and serious environmental issues. Deep nitrogen fertilization involves placing nitrogen at greater depths closer to the plant root zone, which can enhance nitrogen uptake by plants while significantly reducing losses through surface volatilization and leaching. This article discusses the definition, significance, and impact of deep nitrogen fertilization on agricultural production, comparing it with traditional surface fertilization methods. Additionally, it provides analysis of application techniques and optimization, advantages, challenges and risks, as well as application areas and case studies. In conclusion, given the positive effects of deep nitrogen fertilization on plant growth, yield, nitrogen use efficiency and greenhouse gas emissions, it should be widely adopted in agricultural production.
