TUZLU-SODİK ve SODİK TOPRAKLARIN ISLAHINA FARKLI BİR YAKLAŞIM: YEŞİL ISLAH

Abstract

birtakım bitkiler tarafından degradasyona ve ekstraksiyona uğratılarak hareketsizleştirmesi ve bitkinin bünyesine alınması şeklinde tanımlanır. Genellikle yüksek ağır metal içeriğine sahip toprakların ıslahı için kullanılan yeşil ıslahın tuzlu-sodik ve sodik toprakların ıslahında kullanılabilirliği diğer ıslah yaklaşımlarına oranla daha az maliyetli olduğundan dolayı giderek önem kazanmıştır. Bu çalışmanın amacı, tuzlu-sodik ve sodik toprakların ıslahında alternatif olarak kullanılabilecek olan yeşil ıslah yönteminin etkinliğini ortaya koymak ve mekanizmasını değerlendirmektir.

Keywords

• Tuzlu-sodik toprak, sodik toprak, yeşil ıslah
