"Most growers can hand weed their worst problems but these bogs were almost too far gone for that." While their weed problems are similar, the two growers do use different methods of appUcation. Roloff uses a Noble spreader mounted on a special bog buggy he built himself. Thissell uses an electric broad- cast spreader. The two growers state that weeds are more of a problem for growers in their area because the peninsula is so low and they use a water harvest. Much of the peninsula land is below sea level, which means their water table is high. This is good for cranberries but good for weeds, too, they explain. ROLOFF AND THISSELL like to re-sand every seven years, laying down about IVz inches of sand per application with a 4-inch hose. Vines will root in the muck that underlies the area but they dry out quickly unless sanded. The sand also enhances rooting and provides for better moisture uptake in the berries. They prune every year after. DAVE TfflSSELL harvest, which is done by water floating in October. About 100 lbs. per acre of sulfur coated urea (36 percent nitrogen) is applied annually with additional nitrogen supplied through the bog sprinklers. Sprinklers are used for supplemental irrigation during August and September when the area is dry. Once the berries are set, they try to keep the bogs below 80 degrees at the vines. Normally, they will apply about 1 inch of water per week, based on experiment station supplied evaporation-transpiration (ET) data. The sprinklers are also critical for frost control since cranberries can't tolerate temperatures below the 34 to 37 degree range without sustaining injury.
