  Analysis of Basin Characteristics for Stream Management Using GIS: A Case Study of Gümühane Micro-Watershed

  Çakir, Gunay

  Aim of study: Topography and climatic conditions have effected in determining the processes of the streams of the micro-watershed. Nowadays, the management plans were made for water and soil protection measures in the basins. Area of study: This study was carried outto characterize and prioritize the streams of the Gumushane upper Harsit micro-watershed using a GIS-based spatial approach. Material and methods: Fundamental watershed characteristics including drainage density, slope, land use types, and stream class were evaluated and interpreted for the Gumushane micro-watershed. Calculatea comprehensive value for each parameter, drainage density (Dd), flow frequency (Fs), slope (S), length of land flow (Lg), and land use (Lu) was used. Main results: The drainage density, stream flow frequency, and form factor of the microwatershed are from-4 to 26. Finally, the weighted rankings were summarized, and all micro-watersheds were categorized to five classes based on the risk index as very low risk, low risk, medium risk, high risk, and very high risk. This risk map overlaid to land use type maps in GIS where risk areas were evaluated in the finalrisk results. The 739 ha productive forest area within very high-risk areas was changed to non-risk parameters. Highlights: The carrying capacity of streams was calculated using the stream density of streams in the Gumushane micro-watershed. The risk values produced by streams that pass through neighborhoods where land use values for preventing erosion are present.

  Effect of applications of organic solid cattle manure on Hungarian vetch and barley intercropping mixtures grown on soils of different depths

  Yolcu, H.

  Sloping fields on soils of shallow depth to tillage are commonly left uncultivated in many parts of the world. This study was conducted to compare the effects on morphological traits, dry-matter (DM) yield, legume ratio (LR), crude protein content (CP), crude protein yield (CP yield) and mineral concentrations (N, P, K, S, Ca, Cu, Fe, Mg, Mn, Na, B and Zn) of Hungarian vetch (Vicia pannonica Crantz.) and barley (Hordeum vulgare L.) grown in intercropping mixtures in response to three rates of organic solid cattle manure application (M0: 0, M1: 10, M2: 20 t ha-1). Experimentation was conducted on soils of two different soil depths [shallow (8-12 cm; low-medium erosion risk) and normal soil depth (18-22 cm; no erosion risk)] on a sloping field in the 2006-2007 and 2007-2008 growing seasons at Gumushane, Turkey. Herbage harvested on the shallow depth area had 22-73% less DM yield, 14-72% less CP yield, 6-9% greater CP content and generally higher minerals contents than herbage from the normal soil depth area. Cattle manure applications increased DM yield by about 23%, increased CP content and CP yield, and also increased the contents of most minerals in herbage of the intercropping mixtures, relative to the control, averaged over the two soil depths. It is suggested that, for areas with shallow soil depths that are prone to erosion, plant cover should be used for forage production, and that fertilization with solid cattle manure at 20 t ha-1 can support production of quality forage of acceptable DM yield.
