Organik Malç Uygulamalarının Toprağın Bazı Fiziksel Özellikleri Üzerine Etkileri

Bu çalışma, Türkiye’nin Doğu Akdeniz Bölgesinde yarı-kurak iklim koşullarında buğday yetiştirilen arazilerde organik malç uygulamalarından birisi olan buğday samanı uygulamasının toprak özellikleri üzerine etkisini belirlemek amacıyla yapılmıştır. Çalışmada toprak yüzeyine farklı oranlarda (0, 300 kg/da, 600 kg/da ve 900 kg/da) buğday samanı uygulanmıştır. Deneme, arazi koşullarında, tesadüf blokları deneme desenine göre 3 tekerrürlü olarak kurulmuştur. Buğday hasat sonrası her parselden 0-15 cm derinlikten toprak örnekleri alınmıştır. Sonuçta, organik malç uygulamalarından buğday samanının uygulamalara bağlı olarak toprağın organik madde miktarını artırdığı tespit edilmiştir. Ayrıca buğday samanının toprakların likit limit, plastik limit, yarayışlı su içeriği ve tarla kapasitesini de artırmıştır. Uygulama dozuna bağlı olarak toprağın likit limit, plastik limit, yarayışlı su içeriği ve tarla kapasite artışı organik madde ile ilişkilendirilmiştir. Yapılan istatistiksel analiz sonucuna göre, organik madde, likit limit, plastik limit, yarayışlı su içeriği ve tarla kapasitesi üzerine (P

Effects of Organic Mulch Applications on Some Physical Properties of Soil

This study was carried out in order to determine the effect of organic mulch on the soil properties of wheat straw in wheat fields. Turkey's semi-arid climatic conditions in the Eastern Mediterranean Region. In the study, wheat straw in different proportions (0, 300 kg/da, 600 kg/da and 900 kg/da) was applied to the soil surface. The trial was set up with 3 replications according to the randomized blocks trial pattern under field conditions. After the wheat harvest, soil samples were taken from each parcel at a depth of 0-15 cm and analyzed in laboratory. As a result, it has been determined that wheat straw applications, increases the organic matter of the soil depending on the applications. In addition, wheat straw increased the liquid limit, plastic limit, available water content and field capacity of the soils. Depending on the application dose, liquid limit of the soil, plastic limit, available water content and field capacity increase were associated with organic matter. According to the results of statistical analysis, significant differences were found on organic matter, liquid limit, plastic limit, available water content and field capacity (P
