Punch and broadcast sowing used in establishing grass of surfaces sporting facilities. The paper presents the results of studies on suitability of two surface sowings - broadcast and punch sowing. The lawns were used as football piches. The study includes also single and double seeding. On the basis of the results in can be stated that in the year o f establishm ent and for two successive years of...
The paper presents data conceming factors affecting the air conditions in soils. Effect of temperature on respiration of roots and microorganisms are discussed. Grasses has a good tolerance for a low oxygen concentration as compared with other crops. Nevertheless there are differences among species of grasses as regards reaction on oxygen diffusion rate (ODR). Presented data show that the ODR at 1...
A phytosociological method further to Braun-Blanquet was used for the evaluation of the floristic composition of grass surfaces of 10 sports fields in the autumn of 2000 and the spring of 2001. Degrees of quantity and constancy, cover coefficicnts, number of species in a record and sward compactness were studied. Some chemical propertics of the upper soil layer of the sports fields studied was also...
Advances in the preparation of grass mixtures, which occurred in the course of years, resulted in the reduction of the use of single grass species. Utilising increasingly comprehensive information about possibilities of grass competitiveness as well as their response to site conditions, it is easy to select appropriate components for seed mixtures. When deciding to sow a single species, it is essential...
In the year 2000 the investigations aimed at determining the degree of turfness and plant species of 16 football pitches of the Wrocław District League were carried out. It was found that some grass species appeared in the process of natural plant succession, or by sod seeding resulting from grass damage during football games. Weed infestation in the majority of pitches was high (from 6% to 63%),...
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...
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 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...
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...
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...
