Eine pflanzenund umweltgerechte Ausbringung von Flüssigmist ist das Ziel des Projekts „Nährstoffgesteuerte Gülleausbringung“. Hierzu sollen während der Ausbringung von Flüssigmist die Inhaltsstoffe ermittelt werden und die ausgebrachte Flüssigmistmenge je nach Inhaltsstoffgehalt angepasst werden. Eine bedarfsgerechte Ausbringung wird somit realisiert. Bei dem Systemaufbau der Messtechnik wurde ...

Ground water flow was investigated at Clear Lake, a 1468-ha glacial lake in north-central Iowa, as part of a comprehensive water quality study. A multiscale approach, consisting of seepage meters (and a potentiomanometer), Darcy's law, and an analytic element (AE) model, was used to estimate ground water inflow to and outflow from the lake. Estimates from the three methods disagreed. Seepage me...

Grupi and Kashkan marl formations comprise a considerable part of Zagros region. These formations have a considerable erodibility and sedimentation potential because of their special geological and mineralogical characteristics. The objective of this study was to compare the erosion and sediment yield of Kashkan and Grupi formations in Merk watershed located in southeast Kermanshah, using the M...

The GEOgraphic Object-Based Image Analysis (GEOBIA) paradigm continues to prove its efficacy in remote sensing image analysis by providing tools which emulate human perception and combine analyst’s experience with meaningful image-objects. However, challenges remain in the evolution of this new paradigm as sophisticated methods attempt to deliver on the goal of automated geo-intelligence (i.e.,...

Straw mulching is an effective measure to improve soil properties, crop growth, and yield. To further understand the advantage mechanisms of straw mulching, a field experiment with seven straw mulching levels (0 to 18 000 kg ha-1) was conducted to study the effects of straw mulching on maize (Zea mays L.) photosynthesis and rhizosphere soil microecological environment. Results showed that maize...

The article presents the quantitative and qualitative attributes of dead wood in forests dominated by Carpinus betulus L. Kaniv Nature Reserve. study was conducted 130–140-year natural common hornbeam on two permanent sample plots 0.24 ha each identifying measuring all components standing lying (fallen) wood. It found that detritus has an average volume 39.8 m3/ha consists trees (23.1%) fallen ...
