Turkish Journal of Agriculture and Forestry
This study was carried out on the natural range and meadows of Atatürk University in Erzurum, 1996. Recorded species in the study were separated into 16 grasses, 16 legumes and 60 other families. High percentages of the ungrazed species (approximately % 60) indicate that the rangelands have seriously been degrated. In chemical analysis, grasses had the highest crude cellulose content, while legumes had the highest crude protein content, and legumes and other families had the highest mineral element content. In conclusion some wild species on the district rangelands could successfully be utilized in the range improvement.

Turkish Journal of Agriculture and Forestry
Almost %96 of plant species are mycorrhizal infected. Some of them request definitely mycorrhizal infection. Since growth of spores are obligate to the living plant roots, it is nearly impossible to produce mycorrhizal spores under the laboratory conditions. Production of mycorrhizal spores is one of the important step of mycorrhizal work. It is also very important to know the minimum amount of inoculum in order to reach the maximum percentage of infection. The aim of this research was to select the best host plant, in order to obtain high level of mycorrhizal infection, mycorrhizal species and to find the best …

Turkish Journal of Agriculture and Forestry
The method used in transportation of raw forest products can be performed in two phases. The first phase is called " the minor transportation" which is the extraction and hauling of the logs from the felling areas to the landings and intermediate depots. The second phase is "the major transportation". This phase covers the hauling operation from landings and intermediate depots to the log yards or the mill yards. The forestry transportation of harvested woods from compartments is the most difficult and the most expensive operation. Since forests are generally located on high and steep slopes of mountainous area in …

Strength Of Individual Soil Aggregates Against Crushing Forces I. Influence Of Aggregate Characteristics, Taşkin Öztaş, Koray Sönmez, Mustafa Y. Canbolat
Turkish Journal of Agriculture and Forestry
This study was undertaken to determine the relative strength of individual soil aggregates of different sizes and shapes against crushing forces. Soil aggregates were placed individually between a clean-fixed flat surface and a flat plate connected to a pocketpenetrometer and crushed under applied stress. The results of this study show that the strength of the aggregates against disruptive forces was directly related to aggregate size and shape. As the aggregate size increased, so did the applied stress required to crush the aggregate. Significant relationships were found between applied stress and the mass, volume, average diameter (D avg ) and geometric …
