| Abstract/Contents: | "Due to the need for aesthetics, the maintenance of golf courses entails extensive use of turf care products (e.g., pesticides, wetting agents, plant growth regulators). Biostimulants that contain microbial inoculants and/or organic products are often marketed as being more sustainable and cheaper alternatives than the other products. This assumes that biostimulants are better in enhancing the beneficial services of soil microorganisms. However, there is lack of research in evaluating how effective biostimulants are, and how they affect the health of the turfgrass system and turf quality. A field study is currently underway at two locations in Georgia to evaluate the effects of select biostimulants on soil biological health and turf quality. A unique delivery system for applying biostimulants directly in the root zone is also being tested to evaluate its efficacy in improving the survival of microbial inoculants in the soil. Soil biological health was evaluated by determining microbial abundance, function and the soils ability to suppress diseases. Abundance of different microbial groups (total bacteria and fungi, ammonia-oxidizers, nitrogen-fixing bacteria, and arbuscular mycorrhizal fungi) was quantified with quantitative polymerase chain reaction. Microbial function was evaluated by assaying for different enzyme activities that relate to carbon, nitrogen and phosphorous cycling. Fungal pathogens that cause dollar and leaf spots were inoculated to the grass and the progression of the diseases monitored to evaluate the impact of the products on its ability to suppress diseases. Turf quality was evaluated by calculating for normalized difference vegetation index from digital images of plots. The relationship between turf quality and soil biological health were determined using multivariate statistical analysis to identify soil biological health indicators that best predict turf quality." |
