Abstract: In order to study soil nutrient status and the characteristics of mineral elements of different soil textures and tree ages in Munake vineyards, the author took sapling and full fruit vineyards of loam, clay and sandy soil as research objects, analyzed organic matter and nutrient elements (N, P, K, B, Fe, Zn, Mn, Cu) content in 0-20 cm and 20-60 cm depths soil layer. The results showed that the available phosphorus and available potassium contents were at higher level, while the available nitrogen content was at lower level in all soil textures. Total nitrogen of clay was at higher level, and it was at lower level in loam and sandy soil. Effective B, Cu and Fe were at higher level, Mn in sandy soil and Zn in loam soil were at lower level. The organic matter content was at low level in Atux City. Organic matter, total nitrogen, Cu, Fe, Mn in clay soil were much higher than those in sandy and loam soil, The content of organic matter, total nitrogen, Fe, Mn were significantly different between clay and sandy and loam soil. The application of organic fertilizer should be increased and balanced fertilization should be conducted according to different soil textures and tree ages in vineyards of Atux City.
