We like to seed real early in the spring. In fact my father has trained us to ignore the calendar in the spring and simply rely on the environmental conditions. Couple that with few weeds or very young weeds and the high disturbance option makes sense. Seeding barley early is very important to us, it greatly improves our chances of getting into the higher value malt market and also improves our yields. We usually seed about half our farm high disturbance then switch over to the narrow shovels, take off the rod and start spraying in front of the drill.
Canola responds especially well to low disturbance seeding.
For spraying, we have just recently switched from a hooded sprayer to a Melroe Spray Coupe with the E.S.P. system. After 8000 acres of use we are quite pleased with the results. The Coupe is a proven well built machine. The E.S.P. system inot a new idea but Melroe found a way to induce a 40,000 volts charge onto the spray solution which enhances coverage. This first year we were able to test drift reduction and water and chemical rate reduction.
