The aim of the project is to present the role of the plant in effective complementary seeding of grasslands. Two groups of issues were distinguished. The first group is associated with the plant introduced by means of complementary seeding – criteria of species and variety selection, factors affecting sprouting, emergence as well as the growth and development of seedlings. The second group comprises problems associated with the influence of primary vegetation, plants present in the sward of grasslands which are being oversown - plant compatibility and restriction of their effect on seedlings. The paper is the result of studies of literature and own investigations on grassland renovation and, first of all of the author's own considerations. The role of the plant in the process of grassland renovation by complementary seeding is very important. It cannot be limited to the selection of species or cultivar of plants sown under. There is a whole domain of plant properties, beginning with the phase of sprouting and emergence to the stage of full feed utilisation which play a decisive role in the effectiveness of the sod seeding process. Furthermore, this effectiveness is also influenced by the sward vegetation itself into which the introduced species or cultivars are sown. Studies on sod seeding in Poland have continued for a long time, albeit with varying intensity and influenced by altering current technical possibilities. Complementary seeding defined as a method of grassland renovation already seems to be a thing of the past. In future it will be more and more treated as a managing treatment of meadows and pastures similar to fertilisation or irrigation. Pro-ecological character of oversowing and overdrilling rnakes this treatment applicable not only on grasslands but also on objects not connected with forage utilisation, such as lawns and marginal areas. This operation may well serve to increase floristic diversity of meadows, but equally importantly it can be used to re-introduce lost species and reconstruction of grass communities. There are high expectations concerning the plant as the key element in the process of cornplementary seeding. The important question is whether the issue of oversowing and overdrilling is also taken under consideration in the process of breeding work and seed production.

Direct drilling in the climate - soil conditions of Lower Silesia, applied after second cutting in 1993, induced changes in the botanical composition of Poa pratensis association. In the botanical composition of the first cutting in the second year of full utilization (1995) on treatments seeded in summer a considerable participation of Dactylis glomerata, was found, with nitrogen fertilization (180 kg ha⁻¹), both on treatments with weed control (35,9%) and without spraying (33,4%). Festuca pratensis showed slower development and competitiveness, so that its fraction in first cutting ranged between 8,2% and 14% depending on the combination used. Based on the investigations performed, it was found that Dactylis glomerata is the species better suited for direct drilling in the climate-habitat conditions of Lower Silesia.

The experiments on the street lawns were conducted in the years 1986 and 1996-1997. The aim of the experiments was to investigate the changes in the composition of the street lawns sward during the 10 years by estimating the floral composition and the share of living as well as synantrophic forms. The number of plant species in the sward increased from 77% in 1986 to 91% ten years later. Within the same period of time the grass share in the sward cover composition decreased from 59% to 24%. The group of dicotyledonous species was the dominating one. The share of taxons increased considerably within both the leguminous plants group (from 3 to 14 species) as well as the cover composition (from 3,5% to 17%). During the ten years in question the share of lawn plants (of Molinio-Arrhenatheretea) decreased, whilst that of synanthropic plants increased. Among the sward cover composing plants the native species, that is apophytes, dominated. However their share in the sward cover decreased from 96% to 82% during the period under investigation. Both the synantrophic plants as well as the living forms share in the lawn sward influenced the sustainability of lawns. The negative influence is that of the considerable share of the one-year species. During the ten years their share in the sward cover composition increased from 8% in 1986 to 33% in 1996-97. The changes in the lawns composition during the ten-year period influenced the sustainability of lawns. They were positive on one hand - the sward cover increased due to the increased number of taxons. On the other hand they were negative as the share of the ruderal species and that of intruder species increased.

Over a four-year period some microbiological aspects of soil subsystem and proportion of legumes were studied in permanent, oversown and temporary grassland under different level of fertilizer application. The research was carried out in Banská Bystrica, Slovakia, at the altitude of 460 m. The proportion of legumes markedly increased in temporary and oversown grasslands, but decreased with the fertilizer application. There was a positive relationship between CO₂ production in soil and the legume proportion in sward (Figures 1 and 3). However, the correlation between soil CO₂ production and the ratio of soil CO₂ with added N and glucose (NG) to basal CO₂ (B) production (NG/B) was negative. The ratio of NG/B is an indicator of soil organic matter quality (Figures 4 and 5). It was concluded that soil organic matter was more easily degradable in grassland with higher proportion of legumes.

An impact of grass/clover mixtures (3 grass and 2 clover species) oversown to permanent grassland on dry matter production was carried out at five sites of different altitudes (200-960 m) and soil properties (Table 1) in Slovakia during 1993-95. At zero fertilizer application, the grass/clover mixture oversown to grassland increased annual production from 3.54 to 3.97 t ha⁻¹ (i.e. 19%). At application of PK and two rates of N fertilizer (90 and 180 kg N ha⁻¹ + PK), a relative increase in production was 12, 15 and 6%, respectively. The application of PK to sward without grass/clover mixture oversowing enhanced DM production by 29%. A veraged over the research years and sites, savings on fertilizer represented 60 kg N ha⁻¹ as a result of grass/clover mixture oversown to grassland.

In the paper the author presents the own research results and other investigators concern the grassland renovation. He gives criterions which we ought to take into consideration at the election of each method of renovation. Especially strong he underline the fact, that about effectiveness renovation of degraded grassland decide the right election seed mixture and resowing made good. On these factors we ought to wide consider at the renovation degraded grasslands.

In Polish Carpathian Mountains the grasslands localised at the higher location are frequently used as a pasture usually by large sheep's herds. A sward of those pastures belongs to the unit of Lolio-Cynosuretum characterized by strong degradation. It shows among others unfavourable floristic composition with a large number of Nardus stricta. With higher elevation above the sea level, there is more low-valued grass and equally low-valued bifoliate plants in the sward. Improvement of such sward by agronomic practices with proper mineral fertilization is possible and effective but very costly. In the mountains it is connected with possibility of occurring soil erosion. Therefore, one must seek others non-technical methods to trans form pasture sward. In the work results were shown which were obtained by application of grass seeds and papilionaceous directly to the sward in the farm in which sheep spent the night at population of one piece per 1 sq. meter. It was found that organic fertilization alone with fresh excrements as well as introduced species (particularly Dactylis glomerata and Festuca pratensis) in the significant manner changes yields and the florists composition. The greatest favourable changes occurred in the first 2-3 years from the date of oversowing. In this time the yields from different combinations were many times higher than obtained from control plots (0.9 t ha⁻¹). The organic fertilization alone caused yield increase up to 3.95 t ha⁻¹ of dry matter (DM) in the second year and 2.58 t ha⁻¹ (DM) in the third year of investigation. The organic fertilization connected with oversowing contributed to the further plant production increase. For example in the case of oversowing with Festuca pratensis yields in the same years amounted 5.14 and 4.85 t ha⁻¹, for Phleum pratense 5.7 and 3.3 t ha⁻¹ of (DM) respectively. Unfortunately with elapsing time introduced species withdrew from the ward, which caused also the total yield decrease and recession of the florists composition. However, the yield decrease was significantly different. In the last year of investigations yields were in the range from 1.0 to slightly above 2.0 t ha⁻¹ of (DM). The higher yields were obtained with seedlings of Dactylis glomerata, Festuca pratensis and with mixtures in which the above species were dominant.

The study covered permanent meadows on organie soil situated by the Bay of Szczecin, commune of Stepnica. Observations and measurements were carried out in the period of 1996-1997 and aimed at determining the yield of green material by means of random cuttings of 20 sgm spots and yield of dried material at the humidity of 8%. The meadow greenness was also studied to identify 3ts botanical composition by means of botanical-weight analysis. The oversowing markedly increased the annual yield of dried material compared with the control and the conventional tillage. The oversowing and the conventional tillage of the meadow changed and improved the botanical composition of the meadow sward being the base of raw materials of a drying house. In the first year of yielding of the meadows following their regeneration, higher yields of the dried material were obtained from the oversowing applied combination.

Every year forests, meadows, peatbogs and buildings burn. Apart from the economic damage, fires degrade the ecology of the natural environment. Fires disturb the water circle, soil structure and soil microflora. Soil retention and organic matter content decrease, and this in consequence impairs the functioning of ecosystems. Fires are caused, on the one hand, by lack of caution about fire prevention and on the other hand by insufficient use of grass sod. This is in the focus of the author’s attention.
