Field Conditions
Currently, all soils are dry and trafficable with soil moisture deficits (SMDs) ranging from 16 to 60mm. Soils are driest in the east and south with restriction to growth in these areas. A decrease in SMDs is likely as conditions become more unsettled with soils in the west and southwest reaching close to saturation for well-drained soil, and waterlogged for poorly drained soil. Blight advisory: A blight advisory is in effect from Thursday afternoon (28th August) until Friday (29th August) evening. Weather conditions conductive to the spread of potato blight will mostly affect much of the country. There will be some limited opportunities for spraying on Tuesday.
