Sažetak
Calcareous soils often contain large amounts of total iron, however, very small amounts are in the available form for the plants. On soils with high pH values leads to intensive formation of iron compounds, Fe(OH)2+, Fe(OH)3 i Fe(OH)4-, which have low solubility and are the main reason for low plant iron supply on calcareous soils. Iron has low mobility in the plant. Symptoms of deficiency are first observed on young leaves. To solve the problem of iron chlorosis, fertilization of various chelating compounds based on iron and foliar fertilizers are recommended. The aim of this study was to determine the impact of agro-ecological factors (different foliar fertilization, time of sampling and soil lime) on the amount of Fe in the leaves of grapevine in healthy and chlorotic vines. Investigations in 2006 and 2007 included grapevine (Vitis vinifera) cv. Sauvignon white, grafted on SO4 rootstock, planted on highly calcareous soils devided in three groups (low lime – LL, < 20% CaO ; moderate lime – ML, 20-25% CaO ; high lime – HL, >30% CaO). Leaf material was sampled 4 times (twice before, and twice after flowering). Application of Fe increased Fe in the leaves, and at different fertilization treatments are determined values from 90.92 to very high 197.54 mg Fe kg-1. In low lime soils the amount of Fe in the leaves is considerably higher than the other two soil types, and this trend is observed, in both healthy and chlorotic vines. Average values of Fe in the leaves by fertilization treatment was 146.36 mg Fe kg-1, which is much higher than the control. iron foliar fertilization is positively affected the general condition of grapevine On calcareous soils which suggests that this is a good way of solving problems on the soil with a high level of active lime.
