Evaluation of Aquatrols experimental biostimulant formulations on fine turfgrass subjected to wear, nutrient and winter stress
Summary
Five experimental biostimulant formulations were applied biweekly to a USGA green that was sown with a blend of creeping bentgrass (Agrostis stolonifera) varieties. The treatments lasted from 3 June to 6 October and the experimental design was a complete randomised block with four replicates.
The green was fertilised biweekly with a complete balanced fertiliser. The seasonal nitrogen rate was 10 g/m2, which is about 60% of the normal rate for Scandinavian creeping bentgrass greens.
Observations throughout the season included visual assessments of turfgrass (overall impression, colour and density). Chlorophyll index, soil moisture content and root development were also measured. Winter injuries and turf performance were recorded from 20 February to 20 April 2016.
