Arazi kullanım türü değişikliklerinin toprakların bazı fiziksel ve kimyasal özelliklerine etkisinin araştırılması

Abstract

Tokat-Zile ilçesine bağlı Binbaşıoğlu ve Belpınar Köylerinde yürütülen bu çalışmada, arazi kullanım türü değişiklilerinin toprakların bazı fiziksel ve kimyasal özelliklerine etkisi araştırılmıştır. Araştırma konuları Belpınar Köyü sürekli tarım arazisi (A), Belpınar Köyü tarım arazi kullanım türünden orman arazi kullanım türüne çevrilmiş arazi (B), Binbaşıoğlu Köyü sürekli tarım arazisi (C), Binbaşıoğlu Köyü sürekli mera arazisi (D), Binbaşıoğlu Köyü sürekli orman arazisi (E) ve Binbaşıoğlu Köyü ormandan tarıma çevrilmiş arazi (F). Çalışma kapsamında farklı arazi kullanımına sahip toprakların aşınıma duyarlılık, tekstür, çok ince kum, iskelet yüzdesi, agregat stabilitesi, hacim ağırlığı, dispersiyon oranı, hidrolik kondaktivite, kireç, pH, EC ve organik madde gibi özellikleri değerlendirilmiştir. Araştırma konuları dispersiyon oranları %15’in altında olmuş ve erozyona dayanıklı topraklar olarak değerlendirilmiştir. Benzer şekilde, araştırma konuları aşınıma duyarlılık değerleri az ve orta derecede aşınabilir topraklar olarak belirlenmiştir. Sürekli mera ve orman arazilerinde yeterli vejetasyonunun olmaması toprakların organik madde içeriğinin ve agregat stabilitesinin yetersiz olmasında etkili olmuştur. Sürekli tarım, ormandan tarıma dönüştürülen arazi ve tarımdan ormana dönüştürülen arazilerde aradan geçen sürenin 10 yıldan az olması nedeniyle, beklenen olumlu ve olumsuz bariz değişimler gözlenememiştir.

Investigation of the effects of land use type changes on some soil physical and chemical properties

Abstract

This study was carried out to investigate the effects of land use changes on some soil physical and chemical properties in Binbaşıoğlu and Belpınar Villages of Tokat-Zile district. Research topics are as; Belpınar Village continuous farmland (A), Belpınar Village from farmland converted to forestland (B), Binbaşıoğlu Village continuous farmland (C), Binbaşıoğlu Village continuous grassland (D), Binbaşıoğlu Village continuous forestland (E) and Binbasioglu Village from forestland convert to farmland (F). Soil erodibility, texture, very fine sand, coarse material, aggregate stability, bulk density, dispersion ratio, hydraulic conductivity, lime content, pH, EC and organic matter of soils were evaluated. Dispersion ratios were below 15% and were evaluated as resist to erosion. Similarly, the soil erodibility values of research subjects have been identified low-medium erodible soils. Lack of sufficient vegetation in continuous pasture and forestlands has been effective in insufficient organic matter content and aggregate stability of soils. The expected positive and negative changes could not be observed due to less than 10 years of continuous agriculture, forest-to-agricultural and agricultural-to-forestland.
