Abstract/Contents:"Traditional home lawns in the United States favor monocultures of non-native grasses with heavy application of fertilizers and herbicides to compete with weeds. However, mixed stands of turfgrass and clover have been shown to create a dense and even cover that allow for few other weeds and lessens or eliminates the need for fertilizers. Our study evaluates the performance of Kentucky bluegrass (Poa pratensis) in Southern Wisconsin when it is overseeded with different types of clover at different rates. The initial overseeding occurred in 2019 and sampling occurred during the field seasons of 2021 and 2022. Biomass rates, general soil properties, stable isotopic analyses, visual quality, color, percent composition were assessed to examine differences between the treatments. The average daily growth of Microclover overseeded at any rate in 2021 produced the most biomass, but in 2022 any clover overseeded at any rate produced significantly more biomass than the control Kentucky bluegrass. Color ratings and percent cover additionally indicate that any rate of Microclover plots enhances desirable qualities of the lawn. There were not major differences in soil measurements, though some of the plots with higher rates of growth show some minor nutrients to be lower in the soil. N-15 analyses indicate that there may be high instances of nitrogen transfer from clover to Kentucky bluegrass as a key component to the other findings. Our research supports that certain clovers and rates may be suitable for low maintenance, non-fertilized lawns and promote long-term abilities of the soil to support optimal lawn growth with minimal environmental impacts."
