The influence of clay content, organic carbon and land use types on soil aggregate stability and tensile strength

Öz:

Toprakların gerilim direnci ve agregat Stabilitesi değerleri, toprakların strüktürel kalitesinin belirlenmesinde indikatör olarak kullanılabilirler. Bu çalışmada araştırma topraklarının gerilim direnci ve agregat stabiliteleri üzerine toprakların kil içeriğinin, organik karbon miktarlarının ve arazi kullanım tiplerinin etkilerinin belirlenmesi amaçlanmıştır. Toprak örnekleri, Çanakkale-Kumkale Ovasfnın 51 farklı lokasyonundan, Nisan ve Temmuz 2003 tarihlerinde alınmıştır. Örnekleme noktalarının koordinatları küresel konumlandırma sistemi (GPS) kullanarak belirlenmiştir ve örneklerin gerilim direnci, agregat Stabilitesi, organik karbon ve kil içerikleri belirlenmiştir. Toprak analiz sonuçları ve örnekleme noktalarının koordinatları Arc View Coğrafi Bilgi Sistemi (CBS) programına aktarılmıştır. Regresyon analizleri sonucunda toprakların gerilim direnci ile kil içerikleri arasında pozitif lineer ilişki (Nisan örneklemesinde r2 = 0.89 ve Temmuz örneklemesinde r2= 0.92) bulunmuş ve bu ilişkinin kuvveti toprakların organik karbon içeriği. ile doğrusal olarak artmıştır. Mera olarak kullanılan alanların toprak agregat stabiliteleri, diğer tarım arazilerine kıyasla yaklaşık 10 kat daha fazla bulunmuştur. Toprakların agregat stabiliteleri, toprak organik karbonu ile beraber artarken, toprak agregatlarının gerilme dirençleri daha çok kil içeriği tarafından etkilenmiştir. Bununla beraber kil içeriğinin agregatların gerilim direnci üzerine olan etkisi, toprak organik maddesine bağlı olarak artış göstermiştir.

Soil tensile strength (TS) and aggregate stability (AS) values can be used as indicators of soil structural quality. The objective of this study was to determine the influences of land use types, soil carbon and clay contents on soil structure. Soil samples were collected from SI different locations from the Kumkale Basin in Çanakkale in April and July 2003. A global positioning system (GPS) was used to determine the coordinates of sampling points. TS, AS, soil organic carbon (SOC), and clay contents were determined. Results of soil analysis and coordinates of sampling points were transferred to the Arc View geographical information systems (CIS) program. Multiple regression analysis showed that TS was positively related (r2 = 0.89 and 0.92 in April and July, respectively) to clay content when SOC was high. The water stable aggregates in pasture soils were approximately 10 times more water stable than those in other agricultural soils in the region. In general, wet AS was more sensitive to cropping and management systems than TS. Soil AS rose with increasing soil SOC content while TS of soil aggregates was mostly influenced by clay content. However, the effect of clay content on aggregate TS rose with increasing SOC content.
