Název v původním jazyce

Influence of the wood ant, Formica polyctena, on soil nutrient and the spruce tree growth

Popis výsledku v původním jazyce

The effect of Formica polyctena ant nests on the distribution of soil nutrients, soil pH and the growth of Norway spruce trees was studied in the southern part of the Czech Republic. Soil nutrient content (exchange-able P, N, K and pH) and growth of mature spruce trees were measured at four distances from the nearest ant hill (0-1, 3-5, 10-50 and >200 m). Trees at all distances were visited by ants, except for those >200 m from the nearest nest. Soil pH and of P, K and NO3 concentrations were higher near ant nests (<1 m), and pH and K at distances of 3-5 m, when compared with distances of 10-50 and >200 m from the nests, where no significant differences in these variables were detected. In contrast, tree ring analyses (1974-2004) showed that trees >200m from the ant nests grew significantly faster than trees at other distances, followed by trees within 1 m of the nests. No growth differences were found between the growth of trees at 3-5 m and 10-50 m from ant nests.
