NW Washington | Here is a report on seed placed fertilizer that PAMI put out back in 1997 that might help.
The sulfur is going to cause germination problems like nitrogen. Phosphorus is usually not a problem. Row spacing is another factor, that is you can put on more fertilizer per acre (hectare?) with narrow rows because the concentration is less.
