Sažetak
Influence of soil reaction on phosphorus, manganese and iron ratios in grapevine (Vitis vinifera L., cv. Sauvignom Blanck, rootstock) leaves during 2007 and 2008 in northwestern Croatia was investigated. The trial was set up on three vitisol subtypes: dystric cambisol (pHKCl 3, 81), pseudogley (pHKCl 4, 82) and rendzina on marl (pHKCl 7, 38). Leaf samples were taken three times during the vegetation period: at the flowering and verasion stages and at the end of growing period. The lowest P content was determined at the flowering stage in 2007 on acid soil (0.15 % P DM), while the highest P content was determined in the same year at the harvest time on alkaline soil (0.60 % P DM). The highest content of Mn (536.70 mg Mn kg-1 DM) in grapevine leaves was observed at the harvest time 2007 on very acid soil and were 3 to 5 times higher than optimal (30-100 mg Mn kg-1 DM). The lowest content of Mn was determined at the flowering stage 2008 on alkaline soil (22.37 mg Mn kg-1 DM). Lower content of Fe in calcareous soil compared to acid soils were determined at all vegetation phases in 2007, while in 2008 the same trend was recorded only at harvest. In the both investigation years extremely unfavorable P:Mn ratio was determined on acid soils and it was ranged from 3.12 to 24.31. On the alkaline soil, P:Mn ratio was satisfactory in all sampling times in 2007, while during 2008 was significantly wider than the optimum (25-50). Significantly more favorable P:Fe ratio in both years of research in all phases of the vegetation was determined on calcareous soil. Favorable Fe:Mn ratio is determined only on calcareous soil in year 2007, while in 2008 this ratio was unfavorable in all phases of vegetation on acid and calcareous soils.
