Determination of Some Soil Characteristics Depending on Conventional and Reduced Tillage Circumstances

Abstract

In this study, moisture content of soil, soil resistance, bulk density of soil, and soil porosity values

were identified depending on circumstances before tillage process by conventional and reduced tillage methods.

Distribution of soil particle size, mean weight based diameter of soil particles, and the change in roughness rate

of field surface were also determined based on traditional and reduced tillage methods. Trials were conducted

according to factorial regulation in randomized parcels. According to results of the study, the lowest bulk density

and the highest porosity were obtained from reduced tillage method. Tillage method very significantly (P<0.01)

influenced roughness rate. Particles with greater diameter were obtained in conventional tillage method in terms of

mean weighted diameter. Compression ratio of soil arising from tillage method generally increased more in reduced

tillage method. The lowest penetration resistance was obtained in reduced tillage with 0.08 MPa, the highest value

was obtained in the uncultivated area with 2.56 MPa.

Keywords

• Bulk density,penetration resistance,roughness rate,soil particle size,soil tillage

Geleneksel ve Azaltılmış Toprak İşleme Şartlarına Bağlı Olarak Bazı Toprak Özelliklerinin Belirlenmesi

Abstract

Bu çalışmada, geleneksel ve azaltılmış toprak işleme yöntemleri ile toprak işleme öncesi şartlara bağlı

olarak toprağın nem içeriği, toprak direnci, toprağın hacim ağırlığı ve toprak porozitesi değerleri saptanmıştır.

Ayrıca geleneksel ve azaltılmış toprak işleme yöntemlerine bağlı olarak toprak parçacık büyüklük dağılımı, toprak

parçacıklarının ortalama ağırlıklı çapı ve tarla yüzey pürüzlülük oranının değişimi belirlenmiştir. Denemeler tesadüf

parselleri deneme desenine göre yürütülmüştür. Araştırma sonuçlarına göre, en düşük hacim ağırlığı ve en yüksek

porozite değerleri azaltılmış toprak işleme yönteminde elde edilmiştir. Toprak işleme yöntemi, pürüzlülük oranını

çok önemli düzeyde (P<0.01) etkilemiştir. Ortalama ağırlıklı çap bakımından geleneksel toprak işleme yönteminde

daha büyük çaplı parçacıklar elde edilmiştir. Toprak işleme yönteminden kaynaklanan toprağın sıkışma oranı, genel

olarak azaltılmış toprak işleme yönteminde daha fazla artış göstermiştir. En düşük penetrasyon direnci değeri 0.08

MPa ile azaltılmış toprak işlemede, en büyük değer ise 2.56 MPa ile işlenmemiş alanda elde edilmiştir.
