Frost Tactics: Trial 3 Nutrition moderate frost risk locations
Aims

To determine if the application of soil ameloration,  extra nutritional treatments or treatments that will disrupt ice nucleating bacteria will reduce frost damage in a high risk zone.

Sow date 18 May 2022
Harvest date Not specified
Plot size 1.5m x 10m
Plot replication 3
Psuedoreplication Not specified
Plot randomisation Randomised complete block design
Fertiliser

80kg/ha DAP, 90kg/ha SOA, 100kg/ha Urea + treatments 

Other trial notes

Soil ameloriation, nutritional defincincies such as copper and potassium and treatments that effect ice nucleating bacterica levels have been linked changes in frost damage. 

Used 16 different foliar applications around booting, mechanical defoliation at GS31 and nutritional applications at sowing.

Products will only be indentified by their proported benefit eg ice nuclating bacteria reduction, trace element application etc.  

Trial impacted by any unusual or adverse factors: Frost
