Abstract

The objective of this study was to determine direct and indirect effects of some soil properties on soil penetration resistance. The experimental field was gridded with 80 m intervals in the E-W and N-S directions, and soil penetration resistance was measured at 72 intersections using a penetrologger. Soil samples from upper and lower soil layers were also taken at the same points for determining physical and chemical soil properties. The results of study indicated that the highest direct effect to upper soil layer compaction was sand, silt and clay content and the lowest was bulk density. On the other hand, the highest direct effect to subsoil layer compaction was bulk density and lowest was clay content.

Özet

Bu araştırma bazı toprak özelliklerinin penetrasyon direnç değerlerine doğrudan ve dolaylı etkilerinin saptanması amacıyla yürütülmüştür. Bu amaçla çalışma arazisi kuzey-güney ve doğu-batı yönlerinde 80 m aralıklarla transektlere bölünmüş ve transektlerin çakışma noktalarında penetrasyon direnç değerleri ölçülmüştür. Toprakların fiziksel ve kimyasal özelliklerini belirlemek amacıyla üst ve sıkışmış toprak katmanlarından örnekler alınmıştır. Çalışma sonucunda üst toprak katmanı penetrasyon direncine en yüksek doğrudan etkinin kum, silt ve kil içeriğinden olduğu belirlenmiştir. En düşük doğrudan etki değeri ise kütle yoğunluğunda saptanmıştır. Sıkışmış toprak katmanı penetrasyon direncine en yüksek doğrudan etki değeri kütle yoğunluğunda ve en düşük doğrudan etki değeri ise kil içeriğinde görülmüştür.
