Effects of Grazing on Soil Parameters in Meadow Ecosystems

Abstract

This study was carried out to determine the effects of grazing on soil parameters in the meadow ecosystems in the alluvial delta plain of Samsun-Turkey. Five 5×5 m exclosures were established in the homogeneous stands in terms of habitat conditions and floristic composition in the study area during 2000-2003. The top of soil was firstly removed and then soil samples were taken from inside and outside of exclosures at a depth of 20 cm in each month for a year. Soil organic matter, pH, nitrogen, phosphorus, potassium, CaCO3 and total salinity were measured by standard methods. In general, CaCO3 and total salinity exhibited statistically significant differences between the grazed and ungrazed parts.

Çayır Ekosistemlerinde Otlatmanın Toprak Parametrelerine Etkileri

Abstract

B u çalışma Samsun-Türkiye’de alüvyal delta ovalarındaki çayır ekosistemlerinde otlatmanın toprak parametrelerine etkilerini belirlemek için yürütülmüştür. 2000-2003 yıllarında 5×5 m lik beş adet eksklosür çalışma alanında floristik bileşim ve habitat koşulları bakımından homojen alanlarda kurulmuştur. Toprak örnekleri eksklosürlerin içerisinden ve dışından olmak üzere en üst toprak yüzeyi uzaklaştırıldıktan sonra 20 cm derinlikten bir yıl boyunca aylık olarak alınmıştır. Toprak organik maddesi, pH, azot, fosfor, potasyum, CaCOve toplam tuzluluk standart yöntemlerle ölçülmüştür. Genellikle CaCO3 ve toplam tuzluluk otlatılan ve korunan kısımlar arasında istatistiksel olarak önemli derecede farklı çıkmıştır
