Abstract

Excessive use of fossil fuels as an energy source, as well as pressure on the land, results in increased emissions of greenhouse gases and water vapor, which are the main causes of global warming. The increase in emissions of water vapor and greenhouse gases is one of the most significant consequences of human activities. Recently, the development and use of carbon-negative technologies have become important for partially solving problems related to human-induced greenhouse gas emissions. In this context, the use of Biochair material obtained as a product of thermochemical pyrolysis of organic waste in agricultural lands has the potential to reduce greenhouse gas emissions while improving agricultural productivity and food security. The aim of this study is to conduct a meta-analysis of studies conducted to date on the effects of biochar material, which is considered an important soil conditioner, on the physical, chemical, and biological properties of soil, as well as its importance in plant growth and carbon sequestration in the soil

Sürdürülebilir Toprak Üretkenliğinde Biyoçar Kullanımı

Abstract

Fosil yakıtların enerji kaynağı olarak aşırı kullanımının yanı sıra topraklar üzerindeki baskı sonucu sera gazı ve su buharı emisyonlarının artması küresel ısınmanın temel nedenlerini oluşturmaktadır. Zira su buharı ve sera gazlarının emisyonundaki artış insan faaliyetlerinin en önemli sonuçlarından biridir. Son zamanlarda insan kaynaklı sera gazı emisyonları ile ilgili sorunlara kısmi bir çözüm getirmek için karbon-negatif teknolojilerin geliştirilmesi ve kullanılması önem arz etmiştir. Bu bağlamda organik atıkların termo-kimyasal pirolizinin bir ürünü olarak elde edilen biyoçar materyalinin tarım arazilerinde kullanılması potansiyel olarak sera gazı emisyonlarını azaltırken, tarımsal üretkenliği ve gıda güvenliğini iyileştirmesi açısından oldukça önem arz etmektedir. Bu çalışmanın amacı, önemli bir toprak düzenleyici olarak kabul gören biyoçar maddesinin toprağın, fiziko-kimyasal ve biyolojik özelliklerine olan etkisinin yanısıra bitki gelişimi ve toprakta karbon tutumu açısından önemini ortaya koymak için günümüze kadar yapılan çalışmalar konusunda bir meta analiz yapmaktır.
