Research and analysis of the tensile strength quality of the sod in lawn grass stands during landscape design of collective farm enterprises

Studies on evaluating the tensile strength quality of the sod of single-specific and mixed lawn crops have been carried out on sod–podzolic soils in the Ryazan oblast. An evaluation is given for the tensile strength quality of sod in lawn herbage crops over the period of 3 study years. The highest sod tensile strength was recorded in single-specific crops, namely, in creeping red fescue, red fescue, Kentucky bluegrass, and stolon-forming bentgrass; among mixed crops, the highest sod tensile strength was found in the three-component (creeping red fescue, Kentucky bluegrass, and stolon-forming bentgrass) and four-component (stolon-forming bentgrass, red fescue, Kentucky bluegrass, and creeping red fescue) herbage mixture. The lowest tensile strength of the sod was recorded in perennial ryegrass and three-component mixtures (creeping red fescue, sheep fescue, and perennial ryegrass).
