Structure and accumulation of litterfall under Norway spruce stands in connection with thinnings

Popis výsledku v původním jazyce

The effect of thinning on the structure and accumulation of litterfall and holorganic horizons (L, F, H) in young Norway spruce stands was investigated. The research was conducted on a Norway spruce thinning experiment Polom in the Orlické hory Mts. In 1992, the monitoring of litterfall started on an unthinned control stand and on a comparative stand with very heavy thinning from below. During the period of observation, the total weight of litterfall ranged between 1,800 and 4,800 kg/ha. The amount of litterfall was partly influenced by climatic factors, growth processes (basal area increment) and thinning regimes in individual years. The results of the investigations showed that dry biomass accumulated under a 36 years old Norway spruce stand ranged from 9,200 to 11,300 kg/ha in horizon L, from 37,000 to 38,200 kg/ha in horizon F and from 138,300 to 146,400 kg/ha in horizon H. The content of basic nutrients in litterfall and material from holorganic horizons are discussed.
