Fertilizer for use on home lawns and high-cut turfgrass sites including sports fields and golf courses has traditionally been synthetic, and that may be providing excess levels of mineral nutrients. There are concerns over the impact of these fertilizers on water quality following applications to lawns, and the increasing cost of the materials recently used to produce them. Because of this, there is greater interest from homeowners for alternative mineral nutrient sources to apply to their home lawns, and by professional applicators to use in parks or sports fields. This project aims to evaluate the use of soy co–products as an alternative source of mineral nutrients, either in liquid or dry form for fertilization of home lawns and other high–cut turfgrass areas such as sports fields and parks.
This trial is ongoing at three sites – Wooster, OH Columbus, OH and West Lafayette IN. Treatments have been applied as liquid suspension currently with further work planned in 2025.
