On the back-ground of history of lawns, the actual state and the tendency in various methods of growing and production of transferable sod and ornamental lawns in green areas is described.
The determination of the turf grasses seeded in Grass-Paver grate growth and development was the aim of the study. The grate construction is based on the rule of honeycomb. The three grass mixtures (1 Dutch and 2 Polish) and three substratums different in percentage of sand (90, 60, and 40) were analysed in this study. The study has proved that construction margins have not deleriorated the conditions...
The objective of the work wae the effectiveness of 6 herbicides: Barox 460 SL, Boftx 260 EC, Buctril M 560 EC, Kompal 365 SE, Lancet 530 EW and Starane 250 EC. T he studies w ere carried out from May 1 to September 15, 1997, on the lawn in Waryńskiego Square, at Dąbrowskiego Street in Poznań. The studies indicate that none of the applied herbicides exerted any negative effect on the aesthetics of...
The paper present a main causes of the poor quality of sports turf in Poland. It also shows number of different sports field in Poland. In this work we pointed which factors are influenced on their poor quality. It occures that the most important factor which influnced on the of sports turf are, poor prepared substratum and heavy wear. It is proposed to use german’s achievements to project optimum...
The Morskie Oko Park is one of few parks in Warsaw, in which one can to find solutions created to retain storm water. Unfortunately, because of bad technical condition, caused lack of preservation, the existing water system does not function correctly and it demands quick repair and modemization. For that reason a conception of water system revitalization was proposed. It presumes collecting the storm...
Recreation fields demands the soil-waterair system regulation by drainage. A systematic pipe drainage is usually applied in this case. Parks and stand density recreation fields require such a construction of the drainage system that would prevent the roots of the trees and bushes from the drain pipes and water headers damage. In the case of stadiums it is recommended to apply a dense but relatively...
The paper present natural an technical aspects, which need to take account when we want to design sports turf. It is necessary to use habitat information like, weather, water and soil conditions. A very important elements is adaptation suitable mixture of grasses, optimal range and level of cultivation lawns and specification of optimal using of designing sport grounds.
The paper presents preliminary results of studies on the effect of sward type on some football elements. The investigations were performed on three football fields before renovation (hard sward) and on the same fields after renovation (soft sward). The following elements of the play were considered: good shots at the goals, outs and player contusions on a specific field. The study revealed greater...
The paper aimed at finding out the relation between SO2 concentration and air temperature in winter months. The connection between air temperature and sulphur dioxide concentration is related to the temperature value. Decrease of air temperature accompanies inerease of SO2 concentration (the air temperature below -5°C). At the air temperature more than -5°C increase of air temperature accompanies...
One of the reasons for emergency failures and poor sod formation on the grass sports fields can be found in poor seed ąuality of some species included in the mixtures. Moreover, contribution of individual components in the mixture often differs from the composition declared on the package. The studies carried out showed that out of 7 grass mixtures for the sports fields sodding, the share of seeds...
The choosen species and varieties of gazon grasses sown in a pure sowing and mixtures on sport lawns were investigated. In the year of sowing estimated: emergence of plants, propagation and general aspect (scale 9°). Exact experiment microfields founded on 14 may 1998 with split-plot method, there times repeted, on antropogenic soil, formed from loamy sand. Soil before sowing soil was enriched in...
In an experim ent established in 1999 at the premises of the Agricultural University in Poznań, colour changeability of a Kentucky blue-grass lawn developed from Limousine (G) and Ani (PL) cultivars as well as a mixture of Canadian cultivars called Trawan was investigated. During the period of vegetation, the lawn was fertilised with annual quantities of 200 kg/ha N, 70 kg/ha P2O5 and 120 kg/ha K2O...
The article deals with the problem of the pollution mixing in rivers. Only pollutants which are hydrodynamically undistinguishable from a river water are taken into consideration. Is assumed, that the pollutants are passive, are defined as all kinds of chemical substances that mixreadily with water but do not react with it. Pollutants discharged into the river are mixed with the water of river due...
The research was realized in the period form January 1997 to Decem ber 2000. The following characteristics were worked out: precipitation total and wind direction distribution for winter half-year and summer half-year periods and for whole year, monthly sums of precipitation for the period 1997-2000, precipitation wind roses at Ursynów WAU meteorological station. The highest precipitation totals were...
Carried out studies of renovation of destroyed grass surfaces allow ed on stating that there are certain interdependence betw een sun-lit conditions, renovation m ethod and renovation effect in the first year after renovation m easures. On the contrary, the significant differences among surfaces seeded with Polish and foreign mixtures have not been stated. On sites on the eastern side of hedge (sites...
Analitical model of grundwater discharge in two layer medium has been considered. Formulas for drain discharge, pressure in the two layers and lowering of groundwater level have been found.
Poland have poor water resources. What is more, they are unevenly distributed in space and time. Human activity has made water balance even worse in many cases and inerease in the frequency of extreme phenomena such as floods and draughts. One of the methods to improve water balance is development of the so called small retention consists mainly in the inerease of the potential retention abilities...
Breeding work started already in the thirties, but the first six species of lawn grasses were entered into the Register of Cultivars as late as 1966. Dynamic development of the breeding work and species evaluation based on the instructions worked out, started in the eighties (Plant Breeding and Acclimatization Institute, Research Centre for Cultivar Testing). In recent years, there is a growing regress...
Condition of sward of a football green had benn tested during the first year of its utilization. The football field was built on a clay soil, whose top layer of 1 to 5 cm contained peat-mineral material. The large content of floatable parts in the soil caused the fonnation of stagnant water pools during rain, and surface cracks at drought spells. The conditions for grass growth differed also due to...
The paper presents the results of comparing two different ways of renovating run-down swards. The study included depth seeding-punch and slot seeding. The seeds were sown in one, two and three dozes.The factor that decided the success of renovation was, in both cases, a proper opening and penetration of the sod level. Shallow slot seeding and good contact with soil had a positive effect on germination...
