Impact of turfgrass fertilization on nutrient losses through runoff and leaching

“This research project evaluates the use of different types of turfgrass fertilizers and their impacts on nutrient runoff and leaching. The project compares nutrient losses from turfgrass fertilized with natural, synthetic and compost fertilizer sources to unfertilized turfgrass, as well as measuring the impact of cultural practices like aeration, clipping recycling, and overseeding.
The project compared the effect of five different maintenance programs, based on real-life situations, on: turfgrass quality, nutrient losses through runoff and leaching, soil moisture and temperature, and soil fertility level.”

Evaluation of turf fertilization run-off impact and mitigation techniques

A comparison of the effect of four different maintenance programs on turfgrass quality, nutrient losses through runoff and leaching, and soil fertility level. Twelve plots evaluated five different maintenance regimes that included aerification, topdressing, weed control and fertilization. Results suggest that fertilized turf uses less water than unfertilized turf.

Alternative weed control methods and bioherbicides in turf and nursery production

Field trials were conducted on a number of alternative weed control products and it was found that there is significant variation between the claims of manufacturers and actual product performance. Over seeding with some grass species can lead to increased turf cover and is proving to be a favourable option in light of increasing restrictions on pesticide use. This research has delivered a set of clear recommendations for saving money and increasing the efficiency of controlling weeds in turf without conventional herbicides.
