| Description
| - Příspěvek je koncipován jako exkurzní průvodce přinášející informaci o žloutnutí smrkových porostů. V roce 2003 bylo provedeno hodnocení rozsahu žloutnutí v Jizerských horách. Výsledky potvrdily, že 871 ha (LS Frýdlant) a 769 ha (LS Jablonec n. Nisou) bylo postiženo stejným typem poškození. Rok 2003 byl extrémně suchý a část poškozených porostů mohla být ovlivněna suchým počasím a ne narušenou výživou. Chemické analýzy na vybraných lokalitách s projevy žloutnutí ve všech případech prokázaly výraznou nedostatečnost hořčíku a vápníku v jehličí a v lesních půdách a potvrdily fakt, že sucho pouze zesílilo vizuální symptomy vyvolané nedostatečnou výživou porostů. V roce 2003 LČR provedly letecké hnojení na ploše 131 ha, aplikovalo se pomalu rozpustné hnojivo Silvamix Mg-F4 bez dusíku v dávce 300 kg.ha-1. Aplikace hnojiva v takové dávce je střednědobým řešením, pozitivní efekt lze očekávat v období 2-5 let. Zlepšování podmínek bude sledováno (cs)
- The article was drew up as field trip guide bringing an information on yellowing spruce stands in the Jizerské hory Mts. In 2003, assessment of the extent of yellowing spruce stands was done. The results have confirmed that about 871 ha (FA Frýdlant) and769 ha (FA Jablonec n.Nisou) of the spruce stands were affected by this type of decline. Having in mind the fact that the year 2003 was extremely dry, and part of the decline could influenced by dry weather, and not by nutrition disturbance of the stands. However, chemical analyses, in selected localities affected by yellowing, have proved that in all cases significant nutrient insufficiency can be identified in assimilation organs and in forest soil. The results confirmed the conclusion that dryness was only increasing the problems of the stand nutrition. In 2003 the Forests of the CR did aerial fertilising of the forest stands. The positive effect is expected within the horizon of 2 x 5 years. Lasting of the improved conditions will be monitored.
