Zmienność produkcji biomasy na górskich użytkach zielonych w zależności od położenia n.p.m. oraz ekspozycji stoków

Journal Title: Łąkarstwo w Polsce - Year 2015, Vol 18, Issue

Abstract

The article comprises results of the research concerning yielding of grazing sward situated at different altitudes above sea level on slope S and slope N. The results collected for the growing season (April-October) of 2015 are presented in comparison with data from a long series of measurements. They included basic climatic factors (precipitation and temperature) in monthly and ten-day system as well as yielding of grazing sward in subsequent new growth and as a year-round sum. The measurement works were done along earlier determined measurement profile running in N-S system across Grajcarek valley. Samples obtained at predetermined altitude zones during measurements (green biomass) were dried at +105°C to determine the absolute dry weight. The discussed growing season was characterized by high air temperatures and not very favourably distributed precipitation. The average temperature of the vegetation period was 12.9 C and was higher than the multi-year average by 1.2 C. Differences in yielding were varied in respect of both the altitude zones and slope exposure. Depending on location they were between 1.2–4.6 t ha–1 of green biomass and in case of average values including all altitude zones of slope (i.e. 550 – 900 m above sea level) they were as follows: the average yield on slope S was 2.8 t ha–1 and 3.4 t ha–1 on slope N
