Abstract

This study examines the nutritional status of soil and grapevine leaves in vineyards across various regions of Iran, including East Azerbaijan, Qazvin, Shahroud, and West Azerbaijan. The results revealed that nutrient deficiencies in vineyard soils and leaves vary depending on soil characteristics and regional environmental conditions.
In the soils of East Azerbaijan and Qazvin vineyards, deficiencies in organic carbon, phosphorus, and iron were observed. Conversely, the soils in Shahroud and West Azerbaijan faced greater challenges in nutrient availability due to high pH levels, excessive lime content, and saline irrigation water.
Leaf analysis showed that potassium, nitrogen, and calcium—key macronutrients—were deficient in most regions, significantly impacting yield. Additionally, deficiencies in micronutrients such as magnesium, zinc, and iron were particularly pronounced in regions like West Azerbaijan.
Plant tests indicated that unfavorable soil conditions, saline irrigation water, and poor plant nutrition management were the primary factors contributing to these deficiencies.
