Copy link Early season recovery #3
Harrogate 2016
Key Conclusions
Despite the cold spring conditions, all fertiliser treatments initiated a turf response; Cold Start, applied once, and Invigorator, applied twice, led to recovery within 9 days. Cold Start promoting significantly more growth than others, whereas the Potassium Nitrate formulation was the least effective.
Summary:
- The fertiliser treatments all initiated a turf response despite the cold spring conditions
- The amount of Nitrogen was equalised with different application rates and frequency (Cold Start was applied once whilst the others were applied twice)
- The Cold Start and Invigorator plots had recovered through the heavy early season top dressing within 9 days
- The Cold Start initiated significantly more growth than the other fertiliser treatments
- The Potassium Nitrate formulation was found to be the least effective of the fertilisers applied
Objective
A trial to determine the level of recovery through early season top dressing using various different spring fertilisers.
Trial Details
Trial station
Harrogate
Assessments
Height, quality and growth rate
Treatments
All treatments applied to supply 33 Kg of N during the course of the trial.
Heavy dressing
“Heavy” top dressing (2 kg/m2) was applied to each plot 6 days after fertiliser application.
9 days after Heavy top dressing “Heavy” top dressing disappeared in Cold Start and Invigorator plots but still affecting liquids and untreated.
