Technologies for the formation of high-quality turf spaces

The aim of the work was to determine the influence of mineral nutrition on the growth, development and quality of lawn grasses of a football field in the southern regions of Russia. The experiment was carried out on the site of the VGAFK training ground (Volgograd). Water-soluble fertilizers were used: foliar dressing; instant: Urea + Potassium Magnesia, Fertika. The composition of the sown grass mixture: Lolium perenne variety Vesuvius (20 %), Lolium perenne variety Eurocurdus (20 %), Festuca rubra variety Dorianna (20 %), Poa pratensis variety Markus (20 %), Poa pratensis variety Limousine (20 %). Lawn quality was assessed using two methods: A.A. Lapteva and NTEP (National Turfgrass Evaluation Program). The frequency of mowing the lawn will vary depending on light conditions, soil temperature and humidity. But there is a clear dependence on additional mineral nutrition. When applying fertilizers, mowing the lawn should be done every 5-7 days. Without additional mineral nutrition, the haircut should be done once every 7-12 days. It is important that when cutting, 1/3 of the leaf surface is cut off. Recommendations of technological solutions for decompaction of the root layer of the soil of the lawn space, which occur due to intense loads, are presented. It was revealed that the use of the studied water-soluble and instant fertilizers in the conditions of the south of Russia reduces the weediness of the lawn, increases its projective cover and the productivity of shoots of lawn grasses, and increases the breaking load. At the same time, the lawn coverings that are most aligned in height are noted. As a result, the quality and decorativeness of the lawn improve.
