“…The suggested seasonal peaks in fine root biomass in a similar and nearby dry heathland stand reported on by Tinhout & Werger (1988) cannot be traced in our curves for below-ground phytomass. Similarly, Aerts (1993) also reported no seasonal patterns in phytomass values of CaUuna vulgaris heathlands.…”

“…Nevertheless, some seasonal differences were to be expected also in the Genisto-Callunetum, particularly in its belowground phytomass (cf. Tinhout & Werger 1988;Aerts et al 1992;Aerts 1993), as a result of the growth rhythm of CaUuna vulgaris that should cause a dilution effect in late spring and early summer. The seasonal rhythm in N and P concentrations in the above-and below-ground parts of Corynephorus canescens probably reflect the growth cycle of that species, with a large fraction of the above-ground parts dying offin summer as the top soil desiccates, and new growth starting in winter when moisture conditions of the top soil become favourable again (cf.…”

Inland dunes in northwestern Europe support a number of dry vegetation types. These ecosystems are poor in nutrients and it has been suggested that accumulation of nutrients triggers succession in such systems.We studied the accumulation of organic matter and N and P over a 30 months period in two adjacent ecosystems, the Spergulo-Corynephoretum and the Genisto-Callunetum. Amounts of plant matter and soil organic matter significantly accumulated during the sampling period in the Genisto-CaUunetum but not in the SperguloCorynephoretum. While nutrient concentrations of live and dead phytomass in the Spergulo-Corynephoretum were significantly higher than in the Genisto-Callunetum, total nutrient contents in the systems showed the opposite pattern. N and P concentrations in litter were relatively high compared with the other fractions of plant matter and the amount of N significantly increased in both ecosystems during the sampling period. Soil moisture contents showed a seasonal pattern. It was highest in the top soil layer and higher in the Genisto-Callunetum than in the Spergulo-Corynephoretum.The estimated annual increase of total N in these two ecosystems was consistent with rates of atmospheric N deposition (wet fall ÷ dry fall) measured in comparable Dutch sites.

“…Although there are relatively many data on belowground productivity of Calluna stands, reliable data are scarce, because most, of the productivity estimates are based on statistically unreliable calculation methods (i.e. Forrest 197 1';Chapman 1979;Tinhout & Werger 1988). Only Persson's (1978Persson's ( , 1979 data from a boreal pine-heath are statistically sound.…”

Abstract. Root production and turnover were studied using sequential core sampling and observations in permanent minirhizotrons in the field in three dry heathland stands dominated by the evergreen dwarfshrub Calluna yr-' (Deschampsia) and 1.17-1.49 yr-' (Molinia), respectively. No resorption of N and P from senescing roots was observed in either species. Input of organic N into the soil due to root turnover, estimated using the core sampling data, amounted to 1.8 g N m-' yr-' (Calfuna), 1.7 g N mm2 yr-' (Deschampsia) and 19.7 g N rnw2 yr-' (Molinia), respectively. The organic P input was 0.05, 0.07 and 0.55 g P me2 yr-', respectively. Using the minirhizotron turnover estimates these values were 20-22% (Deschampsia) and ll- 30% (Molinia) lower. When the biomass turnover data were used, it appeared that in the Molinia stand root turnover contributed 67% to total litter production, 87% to total litter nitrogen loss and 84% to total litter phosphorus loss. For Calluna and Deschampsia these percentages were about three and two times lower, respectively.This study shows that (1) Root turnover is a key factor in ecosystem C, N, and P cycling; and that (2) The relative importance of root turnover differs between species.
