Study of Physical and Chemical Properties in Grape Garden of Takestan

Grape one of the main of products in Qazvin, however there are problems such as the low average yield and poor quality and of the reason is nutritional disorders. In order to determine nutritional disorders in grape research was conducted in Tkestan. In this study selected 50 sites and were taken soil composite samples of 0-30 and 30-60 cm deep, measured physical and chemical properties contain calcium carbonate, organic carbon, soil texture and available phosphorus and potassium. The result showed that grapes cultivated soils are mostly calcareous and without organic matter in Takestan. Was low organic carbon of about 0.8 percentages, which has an adverse effect on physical properties. In contrast of the low phosphorus in soils, potassium available K than Desirable 300 (mg.kg-1), respectively. Increased calcium carbonate percentage and clay with increasing depth, but decreased organic carbon percentage, pH, available phosphorus and potassium.
