“…Similar as in the PK and Ca pasture plots Trifolium repens occurred often in this plot. Detailed observations on the pasture plots showed that the aggregation of T. repens increased at higher fertilizer dressings (Dirven et al, 1971).…”

In 1958-9, an area of permanent grassland was divided into plots to be used for hay production and given no fertilizer or heavily fertilized with P, K, PK, NPK or Ca and pasture plots left without fertilizer or given PK, NPK or Ca. DM production was estimated yearly and botanical composition and soil fertility analysed at regular intervals. Changes in the plots with a view to ecological indicator values and population dynamics and data on mineral uptake in the different treatments are discussed. Pasture plots not given fertilizer changed the least over the study period. DM yield, spp. diversity and changes in biomass are tabulated for each treatment and spp. present are listed.

“…Rank frequency scores – and consequently the D1:D2:D3 multipliers – increase with increasing size of the sampling units and also with decreasing patchiness of the vegetation ( Dirven et al ., 1971 ; Neuteboom et al ., 1998 ). This will not give bias if one uses sampling units that are small in relation to patch size.…”

A new variant of the dry‐weight rank method for botanical investigation of grassland is described and its usefulness evaluated. Multipliers proportional to the dominance percentages of the three species with the highest dominance percentages are used instead of fixed multipliers. The method is theoretically more valid and applicable to a broader range of grasslands than the variants with fixed multipliers. It does not involve more costs and gives as good or better predictions of the dry‐weight percentages than the variants with fixed multipliers.
