Effect of liming on EUF-nutrient fractions in the soil, on nutrient contents of grape leaves and on grape yield

In pot experiments with vine, liming significantly raised EUF-Ca 20°C as well as EUF-Ca 80°C values of an acid clay soil (pH 4.2). This resulted in a marked rise in Ca contents of vine leaves (Table 2). High amounts of K fertilizers without lime raised mainly the EUF-Ca 20°C values whereas the EUF-80°C values remained at a low level (Table 3). Liming lowered the EUF-K 20°C values and as a result the ratio EUF-K 80°C C/EUF-K 20°C increased from 0.7 to 1.0.

High K applications raised the K content of the leaves at flowering stage but at grape ripening a marked decrease in K content was observed (Table 5). In contrast, the application of both lime and K fertilizer raised the K content of leaves at both flowering and ripening. Grape yield increased as well (Table 11).

Liming raised the EUF-P values of the soil and to a lesser extent the P contents of leaves (Tables 6 and 7).

High K applications without lime raised the Mn contents of leaves (Table 9), Exchange processes due to K fertilizer addition were reflected in increased EUF-Mn values (Table 9).

The highest yield (three-year average) was obtained in a high K treatment (22 g K2O/pot) in combination with lime (40 g CaO/pot).
