Abstract

Çelik cürufları çelik üretimi sırasında oluşan, depolanması veya bertaraf edilmesi çevresel sorun olabilen endüstriyel bir işlemin yan ürünleridir. Çelik cürufları, yüksek miktarda CaO içermeleri nedeniyle, toprak asiditesinin giderilmesinde toprak düzenleyicisi olarak ve aynı zamanda çeşitli konsantrasyonlarda fosfor (P), kükürt (S), mangan (Mn), demir (Fe), molibden (Mo) ve silisyum (Si) gibi bitki besin elementlerine sahip olmaları nedeniyle toprak verimliliğine ve ürün kalitesine katkı sağlamak amacıyla mineral gübre olarak kullanılma potansiyeline sahiptirler. İçerdikleri kalsiyum silikat nedeniyle çelik cürufları buğday, çeltik ve şeker kamışı gibi silisyuma duyarlılık gösteren bazı bitkiler için önemli bir besin elementi kaynağı ve birçok kültür bitkisi için de hastalıklara karşı direnç artırıcı önemli bir ürün olarak tanımlanmaktadır. Bu çalışma kapsamında değerlendirilen literatür bulguları; çelik cüruflarının tarımda alternatif kireçleme materyali olarak asit toprakların ıslahında etkin bir şekilde kullanılabileceğini, önemli miktar ve çeşitlilikte temel bitki besin elementlerine sahip olması nedeniyle toprak verimliliğine ve dolayısıyla da ürün miktarına katkı sağlama potansiyelinin olduğunu ve aynı zamanda doğrudan gübre olarak kullanılabileceği gibi, bitkisel ve hayvansal atıklarla karıştırılıp kompost yapılarak da etkin bir şekilde kullanılabileceğini göstermektedir.

Use of Steel Slags for Agricultural Purposes

Abstract

Steel slags are by-products of an industrial process formed during steelmaking, whose storage or disposal can be an environmental concern. Steel slags, due to their high CaO content, are used as soil conditioners for removing soil acidity and have the potential to be used as mineral fertilizers to contribute to soil fertility and crop quality in various concentrations such as phosphorus, sulfur, manganese, iron, molybdenum, and silicon. Due to their calcium silicate content, steel slags are defined as an important source of nutrients for some plants sensitive to silicon, such as wheat, paddy, and sugar cane, and an important input to increase resistance to diseases for many cultivated plants. This study shows that steel slags can be used effectively in the reclamation of acid soils as an alternative liming material in agriculture, and they have the potential to contribute to soil fertility and thus to crop yield as they contain a significant amount and variety of essential plant nutrients. Steel slags can also be used directly as fertilizer or mixed with vegetable and animal wastes and used as compost.
