Abstract
The main aim of the study is to clarif, the differences in the development of the rill erosion depending on the change of tillage practice and to compute soil loss from rill geometr, on agricultural lands. In the study area, four different fields that are around Acipayam district were chosen to test agricultural practices and each field was divided into three different agricultural practices; unploughed, ploughed across slope, and ploughed down slope. After each natural rainfall event, data were formed with geometric measurement results (length, depth and width) belonging to rill erosion. The relationship between the test results and the changes according to the method of ploughingtice was determined statistically.

Abstract
Bu çalışmanın temel amacı; tarımsal topraklarda, toprağı işleme yöntemlerindeki değişime bağlı olarak çizgi (rill) erozyonunun gelişimindeki farklılıkları ortaya koymak ve çizgilerin geometrik alanlarından toprak kaybını hesaplamak. Amaca yönelik olarak Acıpayam-Kumafşarı çevresindeki eğimli tarım arazilerinden farklı toprak tekstürleri içeren 40x24 m\'lik dört tarla seçilerek; her tarla, konturlara paralel ve dik sürüm ile sürüm yapılmadan bırakılma yöntemleri uygulanarak üçer parsele ayrıldı. Doğal yağmur ortamında her yağış dönemi sonunda oluk erozyonuna ait geometrik (uzunluk, derinlik ve genişlik) ölçüm sonuçları ile data oluşturuldu. Test sonuçlarıyla rill erozyonun sürüm yöntemine göre göstermiş olduğu değişim istatistiksel olarak The main aim of the study is to clarif, the differences in the development of the rill erosion depending on the change of tillage practice and to compute soil loss from rill geometr, on agricultural lands.
